Lewis. 38 00:01:46,060 --> 00:01:48,610 If any of are familiar with the "Lewis Report" of the late 39 00:01:48,610 --> 00:01:52,340 1940s, that's the report that in effect that established the 40 00:01:52,340 --> 00:01:55,320 School of Humanities and Social Sciences. 41 00:01:55,320 --> 00:02:00,460 But here's a chemical engineer who is a very much involved 42 00:02:00,460 --> 00:02:05,250 and looking at all aspects of life at MIT and coming up with 43 00:02:05,250 --> 00:02:06,480 this report. 44 00:02:06,480 --> 00:02:09,340 And as they say, the rest is history. 45 00:02:09,340 --> 00:02:13,070 So Ros has a long lineage here, that your grandfather 46 00:02:13,070 --> 00:02:14,990 goes back to the early 1900s, I would say. 47 00:02:14,990 --> 00:02:16,280 Didn't he get here-- 48 00:02:16,280 --> 00:02:17,665 ROSALIND WILLIAMS: He was class of '05. 49 00:02:17,665 --> 00:02:17,970 PROFESSOR: Yeah. 50 00:02:17,970 --> 00:02:20,820 So she's going to talk about this area. 51 00:02:20,820 --> 00:02:23,380 And she's brought some very interesting materials I'm 52 00:02:23,380 --> 00:02:24,540 anxious to look at. 53 00:02:24,540 --> 00:02:26,680 ROSALIND WILLIAMS: So I wanted to do something new this time. 54 00:02:26,680 --> 00:02:29,380 And that's why in the last hour, I went 55 00:02:29,380 --> 00:02:31,790 though my Lewis box. 56 00:02:31,790 --> 00:02:34,800 Archives are just boxes of stuff. 57 00:02:34,800 --> 00:02:37,890 This is from my attic. 58 00:02:37,890 --> 00:02:40,160 And the library's is just not that different. 59 00:02:40,160 --> 00:02:43,680 And I pulled out some little treasures, at least I think 60 00:02:43,680 --> 00:02:46,750 they're treasures, that will give you a flavor of what 61 00:02:46,750 --> 00:02:50,590 archives are like and when you're doing history, what you 62 00:02:50,590 --> 00:02:54,380 learn from archives that you don't learn online, can't 63 00:02:54,380 --> 00:02:56,830 learn online. 64 00:02:56,830 --> 00:02:58,090 I may overstate that. 65 00:02:58,090 --> 00:02:59,200 I may take that back. 66 00:02:59,200 --> 00:03:02,750 But I'll stand by it for a talking point. 67 00:03:02,750 --> 00:03:07,960 So I'm going to start with giving you an overview of 68 00:03:07,960 --> 00:03:12,270 intertwined biography of Warren K. Lewis and of the 69 00:03:12,270 --> 00:03:18,770 world here in the Boston area, Cambridge, and MIT 70 00:03:18,770 --> 00:03:22,100 specifically, as they intertwined. 71 00:03:22,100 --> 00:03:26,430 And in discussing afterwards, we can talk about him, we can 72 00:03:26,430 --> 00:03:28,395 talk about chemical engineering. 73 00:03:28,395 --> 00:03:31,860 We can also talk about deanly things. 74 00:03:31,860 --> 00:03:35,920 If you're interested in student life history, I've 75 00:03:35,920 --> 00:03:41,030 done a little boning up on that for a documentary that 76 00:03:41,030 --> 00:03:42,890 was being shot last week about the evolution of 77 00:03:42,890 --> 00:03:44,650 student life at MIT. 78 00:03:44,650 --> 00:03:50,070 So I sort of refreshed my memory about some points on 79 00:03:50,070 --> 00:03:52,220 that topic. 80 00:03:52,220 --> 00:03:55,030 So we talk about anything you want to talk about. 81 00:03:55,030 --> 00:03:58,330 But first of all, let me give you some what my grandfather 82 00:03:58,330 --> 00:04:03,000 used to say, you want to put the fodder down where the 83 00:04:03,000 --> 00:04:05,170 calves can get at it. 84 00:04:05,170 --> 00:04:06,780 So I'm going to put out some fodder. 85 00:04:06,780 --> 00:04:09,920 Fodder is food, so cow food. 86 00:04:09,920 --> 00:04:12,600 They say you've got to put it down. 87 00:04:12,600 --> 00:04:14,020 So I'm putting it down. 88 00:04:14,020 --> 00:04:16,860 And we'll chew on this together and then see 89 00:04:16,860 --> 00:04:17,910 where it takes us. 90 00:04:17,910 --> 00:04:24,550 So this is this kind of biographical history of 91 00:04:24,550 --> 00:04:27,060 chemical engineering at MIT. 92 00:04:27,060 --> 00:04:33,320 I remember my grandfather sitting in the living room 93 00:04:33,320 --> 00:04:36,380 holding forth, as he was wont to do, in Newton, 94 00:04:36,380 --> 00:04:37,250 Massachusetts. 95 00:04:37,250 --> 00:04:42,070 This is where he lived with my grandmother and mother and 96 00:04:42,070 --> 00:04:44,430 three other siblings. 97 00:04:44,430 --> 00:04:47,490 He was a boarder in the household 98 00:04:47,490 --> 00:04:48,840 and married the daughter. 99 00:04:48,840 --> 00:04:51,700 And this is a little part history right there. 100 00:04:54,330 --> 00:04:57,040 Most MIT students, there weren't residences. 101 00:04:57,040 --> 00:05:01,100 So you boarded with families or you were in a fraternity. 102 00:05:01,100 --> 00:05:04,250 So boarding was very common. 103 00:05:04,250 --> 00:05:06,390 Let me just me just mention something about his family. 104 00:05:06,390 --> 00:05:07,990 You see his dates. 105 00:05:07,990 --> 00:05:23,300 His father was born in 1845, in Laurel, Delaware. 106 00:05:23,300 --> 00:05:28,940 And his father, my grandfather's grandfather, had 107 00:05:28,940 --> 00:05:35,010 been born in the kind of, well, mid to late 1700s. 108 00:05:35,010 --> 00:05:37,120 He had three wives. 109 00:05:37,120 --> 00:05:40,510 My grandfather's father was the last child 110 00:05:40,510 --> 00:05:41,880 of the third wife. 111 00:05:41,880 --> 00:05:46,303 So there's a huge gap in the half-brothers, between Henry 112 00:05:46,303 --> 00:05:50,180 Clay Lewis, Henry Clay Lewis, that's the name of my 113 00:05:50,180 --> 00:05:55,800 grandfather's father, and the first wife's, first child. 114 00:05:55,800 --> 00:05:56,790 Many of these children died. 115 00:05:56,790 --> 00:06:01,160 But this is just a part of history, the fact that if I go 116 00:06:01,160 --> 00:06:03,690 from my grandfather, to his father, to his father, I'm 117 00:06:03,690 --> 00:06:06,730 back to the Revolutionary War. 118 00:06:06,730 --> 00:06:11,580 Because his grandfather had a brother who died in a prison 119 00:06:11,580 --> 00:06:14,590 ship, moored in the Hudson River during the 120 00:06:14,590 --> 00:06:15,950 Revolutionary War. 121 00:06:15,950 --> 00:06:19,450 So it's just amazing to me that you just take a few steps 122 00:06:19,450 --> 00:06:22,230 and you're back in time, like that. 123 00:06:22,230 --> 00:06:23,270 This is Delaware. 124 00:06:23,270 --> 00:06:25,650 Delaware was a slave state. 125 00:06:25,650 --> 00:06:28,690 It was a slave-owning family. 126 00:06:28,690 --> 00:06:32,500 Also an abolitionist family, which is a strange 127 00:06:32,500 --> 00:06:34,090 combination. 128 00:06:34,090 --> 00:06:37,130 But it's one of those, it's a nice idea, but not until I die 129 00:06:37,130 --> 00:06:38,830 will I free my slaves, family. 130 00:06:38,830 --> 00:06:40,320 And that's what happened. 131 00:06:40,320 --> 00:06:45,320 But his father was one of the two votes for Abraham Lincoln 132 00:06:45,320 --> 00:06:48,360 in his county in Delaware in 1860. 133 00:06:48,360 --> 00:06:51,455 And his father-- 134 00:06:51,455 --> 00:06:53,350 God, these dates don't seem right. 135 00:06:53,350 --> 00:06:56,330 Because if his father is born in 18-- 136 00:06:56,330 --> 00:06:56,760 OK. 137 00:06:56,760 --> 00:07:02,890 It was his grandfather, his last vote was for Abe Lincoln, 138 00:07:02,890 --> 00:07:07,370 that's it, in Laurel, Delaware. 139 00:07:07,370 --> 00:07:10,350 If you look at the history of slavery in Laurel, what's 140 00:07:10,350 --> 00:07:14,810 fascinating is that next door was Maryland, where slaves 141 00:07:14,810 --> 00:07:16,680 could be traded, but not in Delaware, 142 00:07:16,680 --> 00:07:17,530 after a certain date. 143 00:07:17,530 --> 00:07:18,440 You may know that. 144 00:07:18,440 --> 00:07:20,460 But in Delaware, you could hold slaves, but you 145 00:07:20,460 --> 00:07:22,000 couldn't sell them. 146 00:07:22,000 --> 00:07:26,430 So there's a huge kidnapping ring, where people from 147 00:07:26,430 --> 00:07:29,490 Maryland would go just over the border to Laurel, kidnap 148 00:07:29,490 --> 00:07:34,010 either free blacks or slaves, take them back to Maryland, 149 00:07:34,010 --> 00:07:36,720 where they could be sold for a huge profit. 150 00:07:36,720 --> 00:07:39,270 Because at that time, they could still be sold to other 151 00:07:39,270 --> 00:07:40,900 parts of the United States. 152 00:07:40,900 --> 00:07:46,130 So Delaware, Laurel was the site of the Patty Cannon 153 00:07:46,130 --> 00:07:50,820 kidnapping ring, which is a fascinating story. 154 00:07:50,820 --> 00:07:53,010 But it's not the story I'm here to tell. 155 00:07:53,010 --> 00:07:55,830 But it does give context. 156 00:07:55,830 --> 00:07:57,160 This is a farm boy. 157 00:07:57,160 --> 00:08:02,090 Kenny was raised on the farm in Laurel, Delaware. 158 00:08:02,090 --> 00:08:07,090 Expecting to say on the farm, and his life, he got hijacked 159 00:08:07,090 --> 00:08:08,650 by the 20th century. 160 00:08:08,650 --> 00:08:13,130 These are just some more pictures holding forth. 161 00:08:13,130 --> 00:08:17,100 That's a very familiar pose, very familiar. 162 00:08:17,100 --> 00:08:17,320 PROFESSOR: You know it well. 163 00:08:17,320 --> 00:08:18,060 ROSALIND WILLIAMS: Yeah. 164 00:08:18,060 --> 00:08:23,540 I mean as a granddaughter, you knew this guy. 165 00:08:23,540 --> 00:08:26,300 Students were terrified of him because he'd get you up here. 166 00:08:26,300 --> 00:08:28,690 And you'd start doing something on the board. 167 00:08:28,690 --> 00:08:29,560 And you wouldn't know what you were doing 168 00:08:29,560 --> 00:08:31,170 and he would pounce. 169 00:08:31,170 --> 00:08:35,289 But as a granddaughter, it was just a very affectionate 170 00:08:35,289 --> 00:08:36,630 relationship. 171 00:08:36,630 --> 00:08:38,789 I was aware how much he terrified other people. 172 00:08:38,789 --> 00:08:41,460 But that was not my relationship with him. 173 00:08:41,460 --> 00:08:46,420 That's the farmhouse, still in a Laurel, Delaware. 174 00:08:46,420 --> 00:08:48,600 It used to be a bed and breakfast not that long ago. 175 00:08:48,600 --> 00:08:50,610 I don't think it's in business anymore. 176 00:08:50,610 --> 00:08:52,110 That's my brother. 177 00:08:52,110 --> 00:08:55,070 That's more Warren K. Lewis, Jr., my uncle, and my 178 00:08:55,070 --> 00:08:56,300 grandfather. 179 00:08:56,300 --> 00:08:58,560 This is in 1952. 180 00:08:58,560 --> 00:09:01,940 He has just sold the farm. 181 00:09:01,940 --> 00:09:05,570 Heart breaking, because it had been in the family back to the 182 00:09:05,570 --> 00:09:08,140 late 1700s. 183 00:09:08,140 --> 00:09:15,530 But a part of the farm was cut through by a road, the dual, 184 00:09:15,530 --> 00:09:17,420 they call it there, a dual highway. 185 00:09:17,420 --> 00:09:20,290 Route 14 cut through a corner of the farm and he realized it 186 00:09:20,290 --> 00:09:22,780 was never going to be a working farm again. 187 00:09:22,780 --> 00:09:25,600 And the irony is of course that part of the reason for 188 00:09:25,600 --> 00:09:29,890 putting in that highway is that DuPont had established 189 00:09:29,890 --> 00:09:32,250 big factories in northern Delaware. 190 00:09:32,250 --> 00:09:35,460 And there's more commuter traffic from south to north. 191 00:09:35,460 --> 00:09:38,400 So chemical engineering, in a sense, 192 00:09:38,400 --> 00:09:39,820 destroyed the family farm. 193 00:09:39,820 --> 00:09:41,540 And I say there's a sort of irony. 194 00:09:41,540 --> 00:09:43,240 There's quite a bit of irony there. 195 00:09:43,240 --> 00:09:47,130 Not to mention the fact that the whole automobile age was 196 00:09:47,130 --> 00:09:51,280 in part made possible through new methods of refining 197 00:09:51,280 --> 00:09:54,480 petroleum, using catalytic cracking, that my grandfather 198 00:09:54,480 --> 00:09:56,020 directly worked on. 199 00:09:56,020 --> 00:09:58,330 This is not the best-- but this is the Eastern Shore, 200 00:09:58,330 --> 00:09:59,310 this peninsula. 201 00:09:59,310 --> 00:10:01,280 The Chesapeake Bay is here. 202 00:10:01,280 --> 00:10:03,420 So Baltimore is up around here. 203 00:10:03,420 --> 00:10:05,790 Washington is kind of off the map, over here. 204 00:10:05,790 --> 00:10:08,140 And Philadelphia is to the north. 205 00:10:08,140 --> 00:10:10,080 But this is the Eastern Shore. 206 00:10:10,080 --> 00:10:14,280 And it's Virginia down here. 207 00:10:14,280 --> 00:10:15,550 You can't see the map-- 208 00:10:15,550 --> 00:10:16,800 the split division. 209 00:10:21,390 --> 00:10:25,530 So last time I went, I go to the airport in Baltimore, I 210 00:10:25,530 --> 00:10:29,390 drive over the Chesapeake Bay Bridge, I go down to roads, 211 00:10:29,390 --> 00:10:30,900 about right in the middle. 212 00:10:30,900 --> 00:10:33,950 And that takes me two hours. 213 00:10:33,950 --> 00:10:39,325 So you go from one end to the other in a couple hours. 214 00:10:39,325 --> 00:10:41,280 With the dual, you go fast, yeah. 215 00:10:41,280 --> 00:10:43,460 So there is a Maryland over here. 216 00:10:43,460 --> 00:10:45,510 Oh, you can see the dotted line, OK. 217 00:10:45,510 --> 00:10:46,700 So this is Maryland over here. 218 00:10:46,700 --> 00:10:50,680 This is where like Dick Cheney lives now, in Easton. 219 00:10:50,680 --> 00:10:52,915 It's very high, upper crust. 220 00:10:55,750 --> 00:10:57,300 And this is Delaware, which is much more 221 00:10:57,300 --> 00:10:58,620 farming, much more rural. 222 00:10:58,620 --> 00:11:00,000 And then Virginia down here. 223 00:11:00,000 --> 00:11:01,010 It's pretty rustic. 224 00:11:01,010 --> 00:11:03,410 The Chincoteague ponies, Chincoteague is one of these 225 00:11:03,410 --> 00:11:05,140 islands off of here. 226 00:11:05,140 --> 00:11:10,045 So this is a garden spot in the 18th and 19th centuries. 227 00:11:10,045 --> 00:11:14,570 It is the truck garden area for the Philadelphia and 228 00:11:14,570 --> 00:11:20,380 Baltimore markets, raising mainly corn, fruits, 229 00:11:20,380 --> 00:11:24,930 vegetables, peaches, tomatoes, live stock. 230 00:11:24,930 --> 00:11:26,210 It's mixed farming. 231 00:11:26,210 --> 00:11:29,460 And I'll tell you some more about that as we go on. 232 00:11:29,460 --> 00:11:33,230 But the reason I have this map-- this is from Bob Post-- 233 00:11:33,230 --> 00:11:38,510 the railroad comes to Laurel in 1859. 234 00:11:38,510 --> 00:11:43,650 And that opens up the whole area to commercial 235 00:11:43,650 --> 00:11:44,940 farming much more. 236 00:11:44,940 --> 00:11:49,080 I mean it had always been such, but even more. 237 00:11:49,080 --> 00:11:53,560 Now, my grandfather's grandfather was a sea captain. 238 00:11:53,560 --> 00:11:54,940 Farming was his-- 239 00:11:54,940 --> 00:11:57,150 that's where the wife and kids stayed. 240 00:11:57,150 --> 00:12:00,220 But he made his money in the trade, starting from the 241 00:12:00,220 --> 00:12:02,930 Chesapeake, doing a lot of trade of the Caribbean. 242 00:12:06,250 --> 00:12:09,490 So that's where his money came from. 243 00:12:09,490 --> 00:12:14,660 I mean he was a large, established farmer and the 244 00:12:14,660 --> 00:12:15,710 state legislator. 245 00:12:15,710 --> 00:12:20,400 So he was a politician. 246 00:12:20,400 --> 00:12:26,260 But he was a well-off person for Delaware, but still 247 00:12:26,260 --> 00:12:30,080 basically a sea captain and a farmer. 248 00:12:30,080 --> 00:12:33,860 So the railroad comes. 249 00:12:33,860 --> 00:12:37,530 And this is sort of getting ahead of the story. 250 00:12:37,530 --> 00:12:43,490 But my grandfather born in 1882, he goes through the 251 00:12:43,490 --> 00:12:47,370 three-year high school in Laurel, Delaware. 252 00:12:47,370 --> 00:12:49,130 And learns everything you learn there, because there's 253 00:12:49,130 --> 00:12:52,370 one teacher for all grades, in one classroom. 254 00:12:52,370 --> 00:12:55,290 And his parents want him to get a better education. 255 00:12:55,290 --> 00:12:56,640 He's an only child. 256 00:12:56,640 --> 00:12:58,590 He's obviously going to inherit the farm. 257 00:12:58,590 --> 00:13:03,550 So they want him to go to a better high school than the 258 00:13:03,550 --> 00:13:04,570 Laurel one. 259 00:13:04,570 --> 00:13:09,420 So his cousin, she's actually a cousin I guess. 260 00:13:09,420 --> 00:13:13,700 He had an older female cousin named Mary Witherby, who had 261 00:13:13,700 --> 00:13:17,410 left Laurel to teach school, like her father, and she was 262 00:13:17,410 --> 00:13:21,200 teaching school at the Lasell Female seminary, which still 263 00:13:21,200 --> 00:13:22,260 exists around here. 264 00:13:22,260 --> 00:13:23,540 Do any of you-- 265 00:13:23,540 --> 00:13:24,290 you know what I'm talking about. 266 00:13:24,290 --> 00:13:25,150 PROFESSOR: Oh, sure. 267 00:13:25,150 --> 00:13:27,430 ROSALIND WILLIAMS: It's now Lasell College. 268 00:13:27,430 --> 00:13:29,420 It used to be junior college, now college. 269 00:13:29,420 --> 00:13:33,100 Yeah, and it's in West Newton, just a stone's 270 00:13:33,100 --> 00:13:34,270 throw from your place. 271 00:13:34,270 --> 00:13:38,110 So my grandfather was sent up by his parents to live in 272 00:13:38,110 --> 00:13:40,190 Newton, go to high school. 273 00:13:40,190 --> 00:13:43,200 Newton High was famous even then as a good school. 274 00:13:43,200 --> 00:13:44,770 He would board with the family. 275 00:13:44,770 --> 00:13:47,180 But he had his cousin in town. 276 00:13:47,180 --> 00:13:49,280 And she would look after him and make sure he didn't get 277 00:13:49,280 --> 00:13:50,510 into too much trouble. 278 00:13:50,510 --> 00:13:56,300 This house is a block away from where I live now. 279 00:13:56,300 --> 00:13:58,380 I go there all the time. 280 00:13:58,380 --> 00:14:02,230 So that's still there, one of the older houses in the 281 00:14:02,230 --> 00:14:02,630 neighborhood. 282 00:14:02,630 --> 00:14:04,630 So this is where he boarded. 283 00:14:04,630 --> 00:14:13,130 Now, I happen to have his diary from his first full 284 00:14:13,130 --> 00:14:16,570 winter at Hunnewell Avenue in Newton. 285 00:14:16,570 --> 00:14:20,460 And it starts January 10, 1898 and it 286 00:14:20,460 --> 00:14:23,970 goes through the spring. 287 00:14:23,970 --> 00:14:30,000 So I'm a little mixed up about the timing, because I believe 288 00:14:30,000 --> 00:14:32,140 this is his second year I believe at Newton High. 289 00:14:32,140 --> 00:14:39,000 His first year he came up, he got an A in arithmetic, a D in 290 00:14:39,000 --> 00:14:41,350 drawing, and F's in everything else. 291 00:14:41,350 --> 00:14:43,650 So it was not a good high school he was coming from. 292 00:14:43,650 --> 00:14:45,200 And he really had to catch up. 293 00:14:45,200 --> 00:14:49,130 By this time, I think it's the second year, he's got his feet 294 00:14:49,130 --> 00:14:50,520 under him and he's doing better. 295 00:14:50,520 --> 00:14:53,790 So he's boarding in the winter of '98. 296 00:14:53,790 --> 00:14:57,030 And I just want to read a few little details that will give 297 00:14:57,030 --> 00:15:00,010 you a sense of what life was like, daily life was like for 298 00:15:00,010 --> 00:15:02,250 him at that time. 299 00:15:02,250 --> 00:15:05,040 This is the Second Industrial Revolution, is what we call it 300 00:15:05,040 --> 00:15:05,660 from up here. 301 00:15:05,660 --> 00:15:08,100 But down here, this is what it's like. 302 00:15:08,100 --> 00:15:10,310 After school, this is high school, he says, this is 303 00:15:10,310 --> 00:15:15,740 January 12, I went up to Lasell and read Cicero with 304 00:15:15,740 --> 00:15:17,432 cousin Mary. 305 00:15:17,432 --> 00:15:19,976 Who's Cicero? 306 00:15:19,976 --> 00:15:21,655 What does this tell you? 307 00:15:21,655 --> 00:15:23,830 You read Cicero in Latin. 308 00:15:23,830 --> 00:15:26,260 You start with doing Cicero. 309 00:15:26,260 --> 00:15:27,770 You wind up with Cicero and Virgil. 310 00:15:27,770 --> 00:15:31,490 So he's reading his Latin with his cousin. 311 00:15:31,490 --> 00:15:37,740 And then she gave me a supper of canned chicken, cocoa, 312 00:15:37,740 --> 00:15:40,400 bread, butter, crackers, and peanut butter. 313 00:15:40,400 --> 00:15:43,040 I had a fine time. 314 00:15:43,040 --> 00:15:44,770 OK, canned chicken? 315 00:15:44,770 --> 00:15:46,470 I mean I don't have to rub this in. 316 00:15:46,470 --> 00:15:47,360 You can figure this out. 317 00:15:47,360 --> 00:15:48,540 This is not off the farm. 318 00:15:48,540 --> 00:15:52,220 Canned chicken, cocoa, you know we're dealing with the 319 00:15:52,220 --> 00:15:54,970 Caribbean at least, if that's not the East Indies. 320 00:15:54,970 --> 00:15:58,450 Bread, butter, all right, crackers-- 321 00:15:58,450 --> 00:16:01,420 packaged food-- and peanut butter. 322 00:16:01,420 --> 00:16:02,090 OK. 323 00:16:02,090 --> 00:16:06,050 So he mentions that-- at home, he got a letter from home. 324 00:16:06,050 --> 00:16:08,810 And the letter from home says four factories were going up 325 00:16:08,810 --> 00:16:12,230 in Laurel and vicinity for canning. 326 00:16:12,230 --> 00:16:13,300 He, my father-- 327 00:16:13,300 --> 00:16:16,840 this is my grandfather's father, he is going to put out 328 00:16:16,840 --> 00:16:18,090 10 acres of tomatoes. 329 00:16:18,090 --> 00:16:21,620 He has only four cows now. 330 00:16:21,620 --> 00:16:24,390 So there's a lot of agricultural history there. 331 00:16:24,390 --> 00:16:30,470 There's a new canning factory, more tomatoes, fewer cows. 332 00:16:30,470 --> 00:16:35,310 So just to jump ahead, my grandfather would say that he 333 00:16:35,310 --> 00:16:40,580 paid for his MIT tuition when he got to MIT, with tomatoes, 334 00:16:40,580 --> 00:16:43,736 sold to a cannery at $4 a ton. 335 00:16:43,736 --> 00:16:46,260 PROFESSOR: Jesus, $4 a ton. 336 00:16:46,260 --> 00:16:47,430 ROSALIND WILLIAMS: $4 a ton. 337 00:16:47,430 --> 00:16:49,710 Now, he had the bright idea, during his 338 00:16:49,710 --> 00:16:52,760 college years, of recycling. 339 00:16:52,760 --> 00:16:55,540 That is, using the tomato skins, which are removed in 340 00:16:55,540 --> 00:16:58,320 the canning process, or they tried to remove them, using 341 00:16:58,320 --> 00:17:02,340 those skins to feed to the cows as fodder. 342 00:17:02,340 --> 00:17:03,390 And they tried it. 343 00:17:03,390 --> 00:17:04,200 The cows ate them. 344 00:17:04,200 --> 00:17:05,810 But then they gave pink milk. 345 00:17:05,810 --> 00:17:08,660 So it didn't work. 346 00:17:08,660 --> 00:17:11,880 OK, just a few more of these from his diary. 347 00:17:11,880 --> 00:17:14,430 We're still back in January 1898. 348 00:17:14,430 --> 00:17:17,170 Today, as I was walking home from school, cousin Mary in 349 00:17:17,170 --> 00:17:19,260 the electrics-- 350 00:17:19,260 --> 00:17:22,079 so what are the electrics? 351 00:17:22,079 --> 00:17:22,640 PROFESSOR: Trolleys. 352 00:17:22,640 --> 00:17:22,935 ROSALIND WILLIAMS: Trolleys. 353 00:17:22,935 --> 00:17:26,530 OK, the street car suburbs-- 354 00:17:26,530 --> 00:17:27,750 this is a little digression. 355 00:17:27,750 --> 00:17:32,875 But this is showing how the electric trolley system was 356 00:17:32,875 --> 00:17:34,070 being extended at the time. 357 00:17:34,070 --> 00:17:38,080 This is the Sam Best Warner's classic study. 358 00:17:38,080 --> 00:17:42,570 And the trolley, which I remember from my childhood, 359 00:17:42,570 --> 00:17:45,340 near Hunewell Avenue, where he lived, is just a block away. 360 00:17:45,340 --> 00:17:46,150 You can just walk. 361 00:17:46,150 --> 00:17:47,950 In fact, now it's a bus system. 362 00:17:47,950 --> 00:17:49,700 But it's the same route. 363 00:17:49,700 --> 00:17:51,940 And you can get on where we live and go to 364 00:17:51,940 --> 00:17:55,840 Fenway Park in one stop. 365 00:17:55,840 --> 00:17:57,211 PROFESSOR: No wonder you live in that neighborhood. 366 00:17:57,211 --> 00:17:59,460 ROSALIND WILLIAMS: Of course, you got it. 367 00:17:59,460 --> 00:18:01,650 Then we went into Boston. 368 00:18:01,650 --> 00:18:04,340 Cousin Mary in the electrics, saw me, got out and walked 369 00:18:04,340 --> 00:18:04,770 home with me. 370 00:18:04,770 --> 00:18:06,180 Then we went into Boston. 371 00:18:06,180 --> 00:18:08,050 Now, this would have been on the train track, which is the 372 00:18:08,050 --> 00:18:10,475 other side of the hill that he's looking on. 373 00:18:10,475 --> 00:18:11,610 Went into Boston. 374 00:18:11,610 --> 00:18:18,620 And she bought two tin basins, a pie pan, a strainer, and a 375 00:18:18,620 --> 00:18:20,270 dozen knives and forks. 376 00:18:20,270 --> 00:18:22,830 She carried it in a mug strainer belonging to the 377 00:18:22,830 --> 00:18:26,430 coffee pot, to fit the strainer she brought to it. 378 00:18:26,430 --> 00:18:30,400 So she's buying a piece for her coffee pot. 379 00:18:30,400 --> 00:18:31,912 She's buying all this stuff, taking the 380 00:18:31,912 --> 00:18:33,610 electrics into Boston. 381 00:18:33,610 --> 00:18:35,810 So this tells you a lot about technological 382 00:18:35,810 --> 00:18:37,900 systems of the day. 383 00:18:37,900 --> 00:18:43,230 But I think my favorite entry from this 384 00:18:43,230 --> 00:18:49,860 diary, this is in February. 385 00:18:49,860 --> 00:18:51,450 He says, I went downtown. 386 00:18:51,450 --> 00:18:52,500 This would be Newton Corner. 387 00:18:52,500 --> 00:18:56,920 I went downtown in the evening and rode, R-O-D-E, underlined. 388 00:18:56,920 --> 00:19:02,060 I asked a man passing, for a ride, and he consented. 389 00:19:02,060 --> 00:19:05,220 It was the first time, underlined, I've ridden, 390 00:19:05,220 --> 00:19:08,910 underlined, on or behind a horse since last September, 391 00:19:08,910 --> 00:19:12,740 and I a farmer's boy. 392 00:19:12,740 --> 00:19:16,200 So there's cars, there's trolleys, there's trains. 393 00:19:16,200 --> 00:19:18,860 But he wants to ride the horse, because that's what 394 00:19:18,860 --> 00:19:20,570 farmers; boys did. 395 00:19:20,570 --> 00:19:21,390 There's a lot. 396 00:19:21,390 --> 00:19:23,430 I could go on and on about what you find 397 00:19:23,430 --> 00:19:24,560 out from this diary. 398 00:19:24,560 --> 00:19:28,030 There's a lot of reading, Cicero, Shakespeare. 399 00:19:28,030 --> 00:19:29,260 There's a lot of magazines. 400 00:19:29,260 --> 00:19:31,270 He's reading magazines a lot. 401 00:19:31,270 --> 00:19:32,260 He's going to church. 402 00:19:32,260 --> 00:19:33,330 There are church plays. 403 00:19:33,330 --> 00:19:36,110 There are glee club performances at Lasell. 404 00:19:36,110 --> 00:19:39,170 He goes into Boston for lectures at the temple, 405 00:19:39,170 --> 00:19:40,340 Fremont Temple. 406 00:19:40,340 --> 00:19:44,360 He goes to the Museum of Fine Arts, still with us, discusses 407 00:19:44,360 --> 00:19:48,670 modern illustrators who are exhibited there. 408 00:19:48,670 --> 00:19:50,770 Then cousin Mary gives him some pictures. 409 00:19:50,770 --> 00:19:53,920 But I mean it is an information 410 00:19:53,920 --> 00:19:55,050 age, in its own way. 411 00:19:55,050 --> 00:20:00,670 It's just a different kind of media. 412 00:20:00,670 --> 00:20:02,510 But he's very connected. 413 00:20:02,510 --> 00:20:06,900 So, for example, on January 20, he says he goes into 414 00:20:06,900 --> 00:20:09,940 Boston to hear a lecture on imperialism 415 00:20:09,940 --> 00:20:11,580 by Dr. Lyman Abbott. 416 00:20:11,580 --> 00:20:16,140 Now why in 1898, is he going to a lecture on imperialism? 417 00:20:16,140 --> 00:20:17,440 What's going on? 418 00:20:17,440 --> 00:20:18,690 What's the news? 419 00:20:21,150 --> 00:20:21,760 Anybody know? 420 00:20:21,760 --> 00:20:23,110 AUDIENCE: Spanish-American War. 421 00:20:23,110 --> 00:20:24,270 ROSALIND WILLIAMS: OK? 422 00:20:24,270 --> 00:20:24,730 Which-- 423 00:20:24,730 --> 00:20:26,220 PROFESSOR: He said it. 424 00:20:26,220 --> 00:20:27,400 ROSALIND WILLIAMS: Spanish-American War, go to 425 00:20:27,400 --> 00:20:28,870 the head of the class, yeah. 426 00:20:28,870 --> 00:20:31,130 And it's interesting. 427 00:20:31,130 --> 00:20:34,660 He says the lecture was a fine one in favor of staying to 428 00:20:34,660 --> 00:20:37,940 help them, the Filipinos in this case, learn to govern 429 00:20:37,940 --> 00:20:38,730 themselves. 430 00:20:38,730 --> 00:20:41,670 And then he goes to another lecture the next week, same 431 00:20:41,670 --> 00:20:44,950 topic, another speaker, who also make good points. 432 00:20:44,950 --> 00:20:46,760 But cousin Mary said some bad ones. 433 00:20:46,760 --> 00:20:50,080 He attacked, the second speaker, Dr. Abbott, the first 434 00:20:50,080 --> 00:20:53,060 speaker, saying he had made some misstatements concerning 435 00:20:53,060 --> 00:20:56,530 the arguments on Californian annexation and made McKinley 436 00:20:56,530 --> 00:20:58,910 out as having imperial power. 437 00:20:58,910 --> 00:21:02,300 So there's debate going on. 438 00:21:02,300 --> 00:21:05,040 And then on February 7, we received our first news 439 00:21:05,040 --> 00:21:08,360 yesterday of the Battle of Manila. 440 00:21:08,360 --> 00:21:10,800 Reports of dead and wounded, the gunboats 441 00:21:10,800 --> 00:21:12,360 did a fearful execution. 442 00:21:12,360 --> 00:21:14,850 Then there's Washington's birthday soon after, the 443 00:21:14,850 --> 00:21:16,850 church bells ring all day. 444 00:21:16,850 --> 00:21:19,330 And my grandfather writes, these are signs to me that it 445 00:21:19,330 --> 00:21:21,600 is the anniversary of the birth of the greatest 446 00:21:21,600 --> 00:21:25,180 American, underlined, ever borne. 447 00:21:25,180 --> 00:21:26,470 OK, anyway. 448 00:21:26,470 --> 00:21:27,486 PROFESSOR: It wasn't Abe Lincoln. 449 00:21:27,486 --> 00:21:30,045 ROSALIND WILLIAMS: Um, true. 450 00:21:30,045 --> 00:21:30,820 PROFESSOR: It was GW. 451 00:21:30,820 --> 00:21:31,734 ROSALIND WILLIAMS: It was GW. 452 00:21:31,734 --> 00:21:32,191 How about that. 453 00:21:32,191 --> 00:21:32,648 AUDIENCE: [INAUDIBLE]. 454 00:21:32,648 --> 00:21:34,020 ROSALIND WILLIAMS: Yeah. 455 00:21:34,020 --> 00:21:34,910 PROFESSOR: Well, her-- 456 00:21:34,910 --> 00:21:36,410 yeah, but her-- 457 00:21:36,410 --> 00:21:38,070 it would be your great grandfather's-- 458 00:21:38,070 --> 00:21:40,840 whose name is Henry Clay. 459 00:21:40,840 --> 00:21:42,100 Now, Henry Clay-- 460 00:21:42,100 --> 00:21:42,860 ROSALIND WILLIAMS: That's another-- 461 00:21:42,860 --> 00:21:43,540 yeah. 462 00:21:43,540 --> 00:21:47,470 PROFESSOR: But Henry Clay was Abraham Lincoln's 463 00:21:47,470 --> 00:21:49,910 great idol in a way. 464 00:21:49,910 --> 00:21:53,180 ROSALIND WILLIAMS: I mean the story of this family and 465 00:21:53,180 --> 00:21:55,710 slavery is just fascinating. 466 00:21:55,710 --> 00:21:57,010 PROFESSOR: Yeah, it's very interesting, very interesting. 467 00:22:00,290 --> 00:22:02,850 ROSALIND WILLIAMS: Well, I just showed you this paper of 468 00:22:02,850 --> 00:22:05,470 my grandmother's, my grandfather's wife, on the 469 00:22:05,470 --> 00:22:08,150 Negro problem in 1921. 470 00:22:08,150 --> 00:22:11,475 Because my grandfather, he wanted to go back to the farm 471 00:22:11,475 --> 00:22:15,570 and improve race relations by starting that farm up again in 472 00:22:15,570 --> 00:22:16,600 the right way. 473 00:22:16,600 --> 00:22:18,250 And that never happened. 474 00:22:18,250 --> 00:22:19,230 But that was the idea. 475 00:22:19,230 --> 00:22:21,110 OK, instead what happens? 476 00:22:21,110 --> 00:22:24,180 In the spring, he asked two teachers at Newton High what 477 00:22:24,180 --> 00:22:27,400 they thought would be best for him to do about college? 478 00:22:27,400 --> 00:22:29,295 They will think it over, he writes. 479 00:22:29,295 --> 00:22:33,600 But the former advised either Amherst Agricultural-- 480 00:22:33,600 --> 00:22:34,160 what's that? 481 00:22:34,160 --> 00:22:35,330 PROFESSOR: New Mass. 482 00:22:35,330 --> 00:22:36,740 ROSALIND WILLIAMS: Yeah, it's the University of Amherst now, 483 00:22:36,740 --> 00:22:39,780 the Ag School-- other Amherst agriculture, or as even 484 00:22:39,780 --> 00:22:41,330 better, tech. 485 00:22:41,330 --> 00:22:44,520 One of them mentioned Cornell, but tech. 486 00:22:44,520 --> 00:22:45,850 Here we are. 487 00:22:45,850 --> 00:22:48,320 So he thinks about it. 488 00:22:48,320 --> 00:22:51,062 By the way, this is just a picture of downtown Boston, 489 00:22:51,062 --> 00:22:54,010 when they take the train in there. 490 00:22:54,010 --> 00:22:58,950 I was there Friday, meeting my son and his girlfriend. 491 00:22:58,950 --> 00:22:59,680 It's not-- 492 00:22:59,680 --> 00:23:03,280 they're not people like I know. 493 00:23:03,280 --> 00:23:05,840 And I was saying to my son, oh gee, my grandparent's would be 494 00:23:05,840 --> 00:23:07,100 so distressed to see this. 495 00:23:07,100 --> 00:23:09,700 And he said-- he has a place in Fort Point, he said. 496 00:23:09,700 --> 00:23:10,750 But that's up and coming. 497 00:23:10,750 --> 00:23:12,736 That needs to be [INAUDIBLE]. 498 00:23:12,736 --> 00:23:15,950 And now, it's happening. 499 00:23:15,950 --> 00:23:20,620 But let me just mention, I mean these are quick reminders 500 00:23:20,620 --> 00:23:24,270 that the occupation of engineering was growing very 501 00:23:24,270 --> 00:23:27,040 quickly at the time. 502 00:23:27,040 --> 00:23:30,910 And that the people who went into engineering-- 503 00:23:30,910 --> 00:23:35,210 my grandfather is very typical, in being off the farm 504 00:23:35,210 --> 00:23:36,755 and not particularly well educated. 505 00:23:40,570 --> 00:23:45,200 This is the way for young men, almost always young men, to 506 00:23:45,200 --> 00:23:48,310 have a professional or quasi-professional career, 507 00:23:48,310 --> 00:23:51,270 without having to consider postgraduate study, like law 508 00:23:51,270 --> 00:23:56,400 or divinity or medicine required. 509 00:23:56,400 --> 00:23:59,030 So here's Boston Tech. 510 00:23:59,030 --> 00:24:00,890 You must have seen this picture 511 00:24:00,890 --> 00:24:02,470 somewhat, in this class. 512 00:24:02,470 --> 00:24:06,170 Here's Trinity Church in Copley Square. 513 00:24:06,170 --> 00:24:07,770 This is Boston Tech? 514 00:24:07,770 --> 00:24:08,860 PROFESSOR: It's Boston Tech. 515 00:24:08,860 --> 00:24:09,520 ROSALIND WILLIAMS: Yeah. 516 00:24:09,520 --> 00:24:13,440 And I've seen other photos where I can't really place it. 517 00:24:13,440 --> 00:24:16,920 So I would love to see somebody do a sort of up to 518 00:24:16,920 --> 00:24:18,500 date GPS showing exactly-- 519 00:24:21,330 --> 00:24:23,100 AUDIENCE: So that's still there. 520 00:24:23,100 --> 00:24:25,690 ROSALIND WILLIAMS: That's there, yeah. 521 00:24:25,690 --> 00:24:28,252 AUDIENCE: And then across the street from that building is 522 00:24:28,252 --> 00:24:30,741 Brooks Brothers, on Berkeley Street, across from 523 00:24:30,741 --> 00:24:30,970 [INAUDIBLE]. 524 00:24:30,970 --> 00:24:32,586 ROSALIND WILLIAMS: This is all one big building there. 525 00:24:32,586 --> 00:24:33,980 AUDIENCE: Yeah, that's the [INAUDIBLE]. 526 00:24:33,980 --> 00:24:35,690 PROFESSOR: There's actually a plaque on the front of that 527 00:24:35,690 --> 00:24:36,285 office building 528 00:24:36,285 --> 00:24:38,720 ROSALIND WILLIAMS: But there was another building, not the 529 00:24:38,720 --> 00:24:40,210 Rogers Building, but another building, 530 00:24:40,210 --> 00:24:41,430 like off to the side. 531 00:24:41,430 --> 00:24:43,244 PROFESSOR: Yeah. 532 00:24:43,244 --> 00:24:44,160 It would be in that direction. 533 00:24:44,160 --> 00:24:45,670 AUDIENCE: There's a bunch of stuff. 534 00:24:45,670 --> 00:24:49,993 Mark Jarzombek showed us a map, and sort of to the right 535 00:24:49,993 --> 00:24:51,125 of where the photograph is. 536 00:24:51,125 --> 00:24:54,940 There's train tracks and stuff there. 537 00:24:54,940 --> 00:24:57,930 ROSALIND WILLIAMS: Now, the steep steps, was that on this 538 00:24:57,930 --> 00:25:01,560 building, on the Rogers Building, or the second one? 539 00:25:01,560 --> 00:25:03,460 PROFESSOR: I think it's right there. 540 00:25:03,460 --> 00:25:04,340 ROSALIND WILLIAMS: Oh, there. 541 00:25:04,340 --> 00:25:05,050 PROFESSOR: Right there. 542 00:25:05,050 --> 00:25:05,670 ROSALIND WILLIAMS: Oh, OK. 543 00:25:05,670 --> 00:25:06,520 OK. 544 00:25:06,520 --> 00:25:08,930 Because again, my grandfather had a story about a kind of a 545 00:25:08,930 --> 00:25:13,630 riot involving Harvard and MIT students and a fire and he was 546 00:25:13,630 --> 00:25:14,720 on the witness stand. 547 00:25:14,720 --> 00:25:17,280 And it had to do with the steps. 548 00:25:17,280 --> 00:25:19,850 Some things don't change. 549 00:25:19,850 --> 00:25:21,300 AUDIENCE: Mark talked about the difference 550 00:25:21,300 --> 00:25:21,450 between those two-- 551 00:25:21,450 --> 00:25:22,840 ROSALIND WILLIAMS: These two buildings. 552 00:25:22,840 --> 00:25:23,180 AUDIENCE: --buildings. 553 00:25:23,180 --> 00:25:25,764 But they're separated by a couple of decades. 554 00:25:25,764 --> 00:25:29,748 But closer is a custom-built laboratory, where you can see 555 00:25:29,748 --> 00:25:31,242 the fumes of the vents coming at the top there. 556 00:25:31,242 --> 00:25:32,736 ROSALIND WILLIAMS: Oh, that has happened here. 557 00:25:32,736 --> 00:25:34,230 That's fascinating. 558 00:25:34,230 --> 00:25:37,880 So in the subway spot at Kimball, it says the second 559 00:25:37,880 --> 00:25:41,036 building MIT build was a gym, a gymnasium? 560 00:25:41,036 --> 00:25:42,720 Does anybody-- 561 00:25:42,720 --> 00:25:44,830 I just read it there the other day, thinking 562 00:25:44,830 --> 00:25:48,010 that's the first I knew. 563 00:25:48,010 --> 00:25:55,270 So Warren K. Lewis enters MIT in 1901, planning to study 564 00:25:55,270 --> 00:25:58,520 chemical engineer-- excuse me, mechanical engineering, still 565 00:25:58,520 --> 00:26:02,680 the dominant engineering, kind of the default mode. 566 00:26:02,680 --> 00:26:08,310 But he had a friend, this friend that he was boarding 567 00:26:08,310 --> 00:26:13,470 with in Newton, whose sister he eventually married, urged 568 00:26:13,470 --> 00:26:15,110 him to try chemical engineering. 569 00:26:15,110 --> 00:26:19,300 It seemed more interesting and so on and so forth. 570 00:26:19,300 --> 00:26:24,940 So as you know from your reading, something like 571 00:26:24,940 --> 00:26:27,350 industrial chemistry had begun. 572 00:26:27,350 --> 00:26:31,480 Actually, it was 1888, I think was the first offerings in 573 00:26:31,480 --> 00:26:33,020 industrial chemistry. 574 00:26:33,020 --> 00:26:35,090 And by 1893, there was a lab. 575 00:26:35,090 --> 00:26:38,060 This is sort of like the first start of chemical 576 00:26:38,060 --> 00:26:39,290 engineering at MIT. 577 00:26:39,290 --> 00:26:41,110 But then because of deaths and 578 00:26:41,110 --> 00:26:43,400 departures, it sort of declined. 579 00:26:43,400 --> 00:26:47,480 But just when my grandfather's was entering, actually in 580 00:26:47,480 --> 00:26:49,980 1903, this is when Walker comes back. 581 00:26:49,980 --> 00:26:52,110 And Noyes had been there for a couple years. 582 00:26:52,110 --> 00:26:54,770 So it's sort of like a false start early on. 583 00:26:54,770 --> 00:26:57,740 And then it kind of restarted around 584 00:26:57,740 --> 00:26:59,260 the turn of the century. 585 00:26:59,260 --> 00:27:04,710 And this is something that he wrote many years later, that I 586 00:27:04,710 --> 00:27:08,800 think captures the overall feeling of the time. 587 00:27:08,800 --> 00:27:12,070 Lewis wrote, the stimulus of these concepts, and he's 588 00:27:12,070 --> 00:27:15,650 referring to unit operations and these related concepts, 589 00:27:15,650 --> 00:27:18,610 the stimulus of these concepts made work in chemical 590 00:27:18,610 --> 00:27:21,730 engineering at the Institute from 1902 to the outbreak of 591 00:27:21,730 --> 00:27:26,580 World War I an inspiration for both staff and student, which 592 00:27:26,580 --> 00:27:29,400 it is impossible to describe. 593 00:27:29,400 --> 00:27:30,960 So these are happening years. 594 00:27:30,960 --> 00:27:35,870 I mean the tension between Noyes and Walker is a 595 00:27:35,870 --> 00:27:37,120 productive tension. 596 00:27:40,060 --> 00:27:43,290 They had each other to play off of. 597 00:27:43,290 --> 00:27:44,710 And they certainly did. 598 00:27:44,710 --> 00:27:46,830 By the way, you know Walker, that's not 599 00:27:46,830 --> 00:27:49,050 Walker, Memorial Walker. 600 00:27:49,050 --> 00:27:52,660 Walker Memorial is named after Francis Amasa Walker, one of 601 00:27:52,660 --> 00:27:53,950 the early presidents. 602 00:27:53,950 --> 00:27:54,780 Have I got it right? 603 00:27:54,780 --> 00:27:55,610 PROFESSOR: Yup. 604 00:27:55,610 --> 00:27:57,825 ROSALIND WILLIAMS: And we're talking about William Walker. 605 00:28:00,704 --> 00:28:02,290 It's no relation. 606 00:28:02,290 --> 00:28:04,790 So it's important to those straight. 607 00:28:04,790 --> 00:28:09,330 So you have these two very strong personalities. 608 00:28:09,330 --> 00:28:13,960 This is Noyes, trained in Germany, a physical chemist. 609 00:28:13,960 --> 00:28:19,400 And really brought in serious chemistry to the program, 610 00:28:19,400 --> 00:28:21,710 beginning in 1902. 611 00:28:21,710 --> 00:28:26,450 And then you have William H. Walker, who had also been 612 00:28:26,450 --> 00:28:30,280 educated in Germany, Penn State and Gottingen, both. 613 00:28:30,280 --> 00:28:33,960 And was teaching analytical chemistry, the partner of A.D. 614 00:28:33,960 --> 00:28:37,190 Little, which was originally Little and Walker. 615 00:28:37,190 --> 00:28:41,840 So he was entrusted with Course 10 in 1903. 616 00:28:41,840 --> 00:28:45,570 And was entrusted with building it up into a chemical 617 00:28:45,570 --> 00:28:47,330 engineering curriculum. 618 00:28:47,330 --> 00:28:49,750 Now this, you can't read. 619 00:28:49,750 --> 00:28:53,650 But I will read to you, because this is Walker's 620 00:28:53,650 --> 00:28:55,440 statement written years later. 621 00:28:55,440 --> 00:28:56,930 This was after he had left MIT. 622 00:28:56,930 --> 00:29:00,870 This is either from the late '20s or early '30s-- 623 00:29:00,870 --> 00:29:02,840 well, he died in the '30s. 624 00:29:02,840 --> 00:29:05,210 So this is his statement of what he was trying to do. 625 00:29:05,210 --> 00:29:07,200 It's a fascinating statement. 626 00:29:07,200 --> 00:29:10,800 So I'm going to read you what Walker wrote. 627 00:29:10,800 --> 00:29:15,940 What an industry needed was not a man who had been taught 628 00:29:15,940 --> 00:29:19,010 what the industry already knew, but rather a man who was 629 00:29:19,010 --> 00:29:20,880 trained to do what the industry had not 630 00:29:20,880 --> 00:29:23,080 been able to do. 631 00:29:23,080 --> 00:29:25,900 The ideal man for the industries was one who had 632 00:29:25,900 --> 00:29:28,420 been given a sound knowledge of chemistry and physics. 633 00:29:28,420 --> 00:29:31,030 And then as a part of the curriculum, had been given 634 00:29:31,030 --> 00:29:34,560 systematic experience in the application of this knowledge 635 00:29:34,560 --> 00:29:36,980 to the solution of industrial problems. 636 00:29:36,980 --> 00:29:39,800 That he should not be a specialist, but a solver of 637 00:29:39,800 --> 00:29:43,740 problems, any kind of problem that industry might present. 638 00:29:43,740 --> 00:29:46,580 And then he goes on to say, this idea met opposition, both 639 00:29:46,580 --> 00:29:48,320 from established courses of chemical 640 00:29:48,320 --> 00:29:50,525 instruction and from industry. 641 00:29:50,525 --> 00:29:53,620 And the industry thought it was too theoretical. 642 00:29:53,620 --> 00:29:57,200 But the scientists thought it was too industry oriented. 643 00:29:57,200 --> 00:30:02,350 So Walker is on this very nice edge between not trying to 644 00:30:02,350 --> 00:30:03,870 give into one or the other. 645 00:30:03,870 --> 00:30:05,380 And then he goes on and says-- 646 00:30:05,380 --> 00:30:07,790 this at the top of the second paragraph, I love this-- 647 00:30:07,790 --> 00:30:09,560 to prove the soundness of this idea, I 648 00:30:09,560 --> 00:30:11,760 returned to MIT in 1903. 649 00:30:11,760 --> 00:30:14,810 And after a hot fight with both the chemical and the 650 00:30:14,810 --> 00:30:17,960 engineering faculties, I reconstructed Course X as a 651 00:30:17,960 --> 00:30:21,050 general educational course without options. 652 00:30:21,050 --> 00:30:23,480 And without options, that turns out to be important. 653 00:30:23,480 --> 00:30:25,560 So this is a feisty guy. 654 00:30:25,560 --> 00:30:27,990 And I'm sure that's one reason he and my grandfather got 655 00:30:27,990 --> 00:30:29,070 along very well. 656 00:30:29,070 --> 00:30:34,270 They were both feisty people, very self assured. 657 00:30:34,270 --> 00:30:37,440 But my grandfather always would say, it is Walker who 658 00:30:37,440 --> 00:30:40,090 invented chemical engineering in this country. 659 00:30:40,090 --> 00:30:43,310 He did not claim that for himself at all. 660 00:30:43,310 --> 00:30:45,410 But again, my grandfather studied. 661 00:30:45,410 --> 00:30:47,520 With Noyes. 662 00:30:47,520 --> 00:30:49,750 You know, I was just reminding you, this is particularly in 663 00:30:49,750 --> 00:30:51,630 Servos's article. 664 00:30:51,630 --> 00:30:55,510 My grandfather studied with Noyes, took P-Chem from him, 665 00:30:55,510 --> 00:31:02,290 and graduating in the class of '05. 666 00:31:02,290 --> 00:31:04,416 My grandfather's is this kind of this grim-- he looks-- kind 667 00:31:04,416 --> 00:31:07,690 of a grim looking guy. 668 00:31:07,690 --> 00:31:08,700 And you'll see another picture. 669 00:31:08,700 --> 00:31:10,370 I'll pass it around. 670 00:31:10,370 --> 00:31:13,440 In the spring of his senior year, he expected to go back 671 00:31:13,440 --> 00:31:16,510 to the farm, as much as you and I expect the Sun to come 672 00:31:16,510 --> 00:31:17,190 up tomorrow. 673 00:31:17,190 --> 00:31:24,920 However, he got a job in the lab, I think with Noyes. 674 00:31:24,920 --> 00:31:29,320 And then that led to somebody, I don't know whether it was 675 00:31:29,320 --> 00:31:32,350 Noyes or Walker, one of them suggested that he apply for a 676 00:31:32,350 --> 00:31:34,770 traveling fellowship which was being offered. 677 00:31:34,770 --> 00:31:38,280 And it was $1,000 stipend, which is that day and age was 678 00:31:38,280 --> 00:31:40,140 a lot of money. 679 00:31:40,140 --> 00:31:42,330 A traveling fellowship, he could go 680 00:31:42,330 --> 00:31:44,070 anywhere for a doctorate. 681 00:31:44,070 --> 00:31:46,510 And so he really was not interested. 682 00:31:46,510 --> 00:31:50,840 But one of them basically appealed to his competitive 683 00:31:50,840 --> 00:31:54,010 spirit and kind of said well, if you don't get it, somebody 684 00:31:54,010 --> 00:31:54,880 else is going to get it. 685 00:31:54,880 --> 00:31:56,970 And $1,000 sounded very nice. 686 00:31:56,970 --> 00:32:02,545 He applied, got it and was on his way to Breslau, in what is 687 00:32:02,545 --> 00:32:05,310 now Germany, it's kind of on the Polish-German border, for 688 00:32:05,310 --> 00:32:07,640 graduate school the next year. 689 00:32:07,640 --> 00:32:12,715 Later, he found he was in fact the only applicant that year. 690 00:32:12,715 --> 00:32:14,200 PROFESSOR: Well, it's interesting. 691 00:32:14,200 --> 00:32:17,170 Think about what the Harvard class of 1905, where they 692 00:32:17,170 --> 00:32:19,650 might have chosen to have their picture taken. 693 00:32:19,650 --> 00:32:19,955 ROSALIND WILLIAMS: Aah. 694 00:32:19,955 --> 00:32:22,962 AUDIENCE: I'm sure it was not in the laboratory. 695 00:32:22,962 --> 00:32:23,950 ROSALIND WILLIAMS: Yeah, yeah. 696 00:32:23,950 --> 00:32:28,938 I mean this is a good example, where it tells you so much. 697 00:32:28,938 --> 00:32:30,930 It does. 698 00:32:30,930 --> 00:32:33,072 Began with the names and faces. 699 00:32:33,072 --> 00:32:34,458 AUDIENCE: Books piled up in the front of them. 700 00:32:34,458 --> 00:32:35,382 ROSALIND WILLIAMS: Yeah. 701 00:32:35,382 --> 00:32:37,700 So-- 702 00:32:37,700 --> 00:32:39,550 AUDIENCE: What's in the books on the front? 703 00:32:39,550 --> 00:32:40,390 ROSALIND WILLIAMS: Yeah. 704 00:32:40,390 --> 00:32:42,390 Oh yeah, that's great. 705 00:32:45,180 --> 00:32:52,200 So this is his dissertation in German, from Breslau, three 706 00:32:52,200 --> 00:32:53,910 years later. 707 00:32:53,910 --> 00:32:59,040 He wrote it in Florence, because he thought Florence 708 00:32:59,040 --> 00:33:01,040 was the most beautiful city in the world, and why not write 709 00:33:01,040 --> 00:33:02,070 your dissertation there? 710 00:33:02,070 --> 00:33:04,870 I recommend that highly, if any of you write 711 00:33:04,870 --> 00:33:07,320 dissertations. 712 00:33:07,320 --> 00:33:08,680 But this is Germany. 713 00:33:08,680 --> 00:33:11,400 And just keep that in mind when we get to World War II. 714 00:33:11,400 --> 00:33:12,314 PROFESSOR: Yeah, yeah. 715 00:33:12,314 --> 00:33:13,230 AUDIENCE: World War I. 716 00:33:13,230 --> 00:33:15,820 PROFESSOR: And he was sufficiently literate in 717 00:33:15,820 --> 00:33:17,000 German to be able to write a dissertation. 718 00:33:17,000 --> 00:33:17,440 ROSALIND WILLIAMS: Yeah. 719 00:33:17,440 --> 00:33:17,740 Yeah. 720 00:33:17,740 --> 00:33:20,730 Well, he never felt his German was that great. 721 00:33:20,730 --> 00:33:24,710 And in fact, back to Latin, a story he tells us taking the 722 00:33:24,710 --> 00:33:27,570 train to Italy, or maybe back from Italy. 723 00:33:27,570 --> 00:33:30,830 But in any case, he was seated next to somebody-- maybe they 724 00:33:30,830 --> 00:33:32,220 were like Polish or something. 725 00:33:32,220 --> 00:33:34,040 But German didn't work. 726 00:33:34,040 --> 00:33:35,290 The other person didn't know English. 727 00:33:35,290 --> 00:33:37,600 So they conversed in Latin. 728 00:33:37,600 --> 00:33:38,110 PROFESSOR: Is that right? 729 00:33:38,110 --> 00:33:39,250 ROSALIND WILLIAMS: You never know. 730 00:33:39,250 --> 00:33:39,460 PROFESSOR: It's fascinating. 731 00:33:39,460 --> 00:33:41,970 ROSALIND WILLIAMS: It may come in handy. 732 00:33:41,970 --> 00:33:44,560 So then he comes back to-- 733 00:33:44,560 --> 00:33:47,810 well, he has a year working at a tannery in 734 00:33:47,810 --> 00:33:50,190 Manchester, New Hampshire. 735 00:33:50,190 --> 00:33:52,640 And as a result of that experience, he always said 736 00:33:52,640 --> 00:33:54,750 tanneries do not have to pollute. 737 00:33:54,750 --> 00:33:57,350 It's not necessary, if you run them right. 738 00:33:57,350 --> 00:33:59,560 And they don't have to smell either, that's the other thing 739 00:33:59,560 --> 00:34:01,720 you associate was a tannery. 740 00:34:01,720 --> 00:34:06,480 So he comes back. 741 00:34:06,480 --> 00:34:12,300 And you can see how chemical engineering around 1910, 742 00:34:12,300 --> 00:34:16,489 there's this kind of reversal of who was majoring in what. 743 00:34:16,489 --> 00:34:19,840 And this is before the war. 744 00:34:19,840 --> 00:34:25,060 Because when World War I comes, even before the US 745 00:34:25,060 --> 00:34:29,570 enters World War I, the Great War, in 1917, there's a 746 00:34:29,570 --> 00:34:34,330 tremendous demand for military equipment. 747 00:34:34,330 --> 00:34:39,219 And chemical engineering is connected with gas warfare, 748 00:34:39,219 --> 00:34:42,909 which was used right near the beginning of the war. 749 00:34:42,909 --> 00:34:47,560 It was in the spring of 1915 that chlorine was first used 750 00:34:47,560 --> 00:34:51,440 on the battlefield as a poison gas. 751 00:34:51,440 --> 00:34:53,922 Chlorine is not the most effective, by any means. 752 00:34:53,922 --> 00:34:55,679 It dissipates pretty quickly. 753 00:34:55,679 --> 00:34:59,880 But the surprise factor was such that it really did work 754 00:34:59,880 --> 00:35:01,310 in the initial use. 755 00:35:01,310 --> 00:35:05,650 And it had a tremendous psychological effect in 756 00:35:05,650 --> 00:35:10,340 scaring people on both sides. 757 00:35:10,340 --> 00:35:14,170 So Walker, William Walker, was put in charge of the Edgewood 758 00:35:14,170 --> 00:35:17,710 Arsenal, once the US entered the war, to 759 00:35:17,710 --> 00:35:19,780 manufacture toxic gases. 760 00:35:19,780 --> 00:35:24,790 And my grandfather was put in charge of gas defense. 761 00:35:24,790 --> 00:35:27,160 So he worked on the masks. 762 00:35:27,160 --> 00:35:28,460 And there's all sorts of-- 763 00:35:28,460 --> 00:35:32,860 I mean this is very specialized equipment. 764 00:35:32,860 --> 00:35:36,240 And to try to design equipment that made it possible to keep 765 00:35:36,240 --> 00:35:39,770 fighting and yet would protect the soldier from poison gas, 766 00:35:39,770 --> 00:35:42,276 not just the soldier but-- 767 00:35:42,276 --> 00:35:45,720 do I have some of the-- the animals too. 768 00:35:45,720 --> 00:35:49,030 In fact, there's a whole long story about the horses being 769 00:35:49,030 --> 00:35:51,520 affected by mustard gas, which is a vesicant. 770 00:35:51,520 --> 00:35:53,620 And it's a much nastier gas. 771 00:35:53,620 --> 00:35:55,680 And it would affect the animals too. 772 00:35:55,680 --> 00:35:58,730 So the one story that I need to tell you about my 773 00:35:58,730 --> 00:36:05,490 grandfather and gas defense, this made such an 774 00:36:05,490 --> 00:36:08,370 impression on me. 775 00:36:08,370 --> 00:36:09,935 We had this conversation was I was a teenager. 776 00:36:14,990 --> 00:36:19,090 Let's see, he said there was not a single Allied soldier-- 777 00:36:19,090 --> 00:36:20,423 am I taking too much? 778 00:36:20,423 --> 00:36:20,525 PROFESSOR: No, no. 779 00:36:20,525 --> 00:36:22,360 ROSALIND WILLIAMS: It won't take much longer. 780 00:36:22,360 --> 00:36:27,570 There's not a single Allied soldier is World War I who 781 00:36:27,570 --> 00:36:32,530 died from poison gas when they had the gas mask and other 782 00:36:32,530 --> 00:36:34,060 equipment on. 783 00:36:34,060 --> 00:36:37,960 And I grandpa, you must been so proud because you designed 784 00:36:37,960 --> 00:36:41,840 something that was fail-safe. 785 00:36:41,840 --> 00:36:43,330 It worked every time. 786 00:36:43,330 --> 00:36:48,020 And he said no, it means I over designed. 787 00:36:48,020 --> 00:36:54,140 And what he meant was the cost of putting on a 788 00:36:54,140 --> 00:36:55,360 mask is quite high. 789 00:36:55,360 --> 00:36:57,820 It's makes it hard to breathe. 790 00:36:57,820 --> 00:36:59,310 And it does encumber you. 791 00:36:59,310 --> 00:37:04,020 So in designing the gas mask, you have to make 792 00:37:04,020 --> 00:37:07,110 it just on the edge. 793 00:37:07,110 --> 00:37:10,210 Because then, soldiers are more likely to put it on in 794 00:37:10,210 --> 00:37:11,660 the first place. 795 00:37:11,660 --> 00:37:15,000 So by over designing it, it meant that he was surmising 796 00:37:15,000 --> 00:37:16,650 that more people had died but not putting 797 00:37:16,650 --> 00:37:17,890 on the mask at all. 798 00:37:17,890 --> 00:37:21,050 Because it was such a pain to put on. 799 00:37:21,050 --> 00:37:25,910 And for an engineer to think that way about human life, it 800 00:37:25,910 --> 00:37:29,182 just really took me aback. 801 00:37:29,182 --> 00:37:33,850 And I thought, boy, that's responsibility. 802 00:37:33,850 --> 00:37:38,230 After he died in 1975, you clean out the house of the 803 00:37:38,230 --> 00:37:40,370 person who has passed on. 804 00:37:40,370 --> 00:37:47,510 And down in the cellar, big basement, in the furnace room 805 00:37:47,510 --> 00:37:48,790 there are these shelves. 806 00:37:48,790 --> 00:37:53,340 And there were all these gas masks lined up on the shelves. 807 00:37:53,340 --> 00:37:58,450 And it turned out at the end of the war, the Allied troops 808 00:37:58,450 --> 00:38:01,860 have given him a model of each of the gas masks that had been 809 00:38:01,860 --> 00:38:03,760 used by the Allies in the war. 810 00:38:03,760 --> 00:38:07,590 So he had this collection of gas masks that were just 811 00:38:07,590 --> 00:38:08,770 sitting down there. 812 00:38:08,770 --> 00:38:12,325 And I called the Smithsonian and I called the MIT Museum, 813 00:38:12,325 --> 00:38:14,410 and I said I think this is really interesting. 814 00:38:14,410 --> 00:38:16,705 But nobody took the gas masks. 815 00:38:16,705 --> 00:38:20,606 So they have thrown out, because I tried. 816 00:38:20,606 --> 00:38:22,550 I tried. 817 00:38:22,550 --> 00:38:24,206 AUDIENCE: You weren't tempted to just mount them on wall in 818 00:38:24,206 --> 00:38:26,420 your living room? 819 00:38:26,420 --> 00:38:28,180 ROSALIND WILLIAMS: Well, they're odd. 820 00:38:28,180 --> 00:38:31,090 Well, I mean we'd been looking at pictures from Japan, 821 00:38:31,090 --> 00:38:32,170 testing children. 822 00:38:32,170 --> 00:38:36,380 And when you get in a haz suit, it's really scary. 823 00:38:36,380 --> 00:38:37,710 It's just very curious, period. 824 00:38:37,710 --> 00:38:39,343 So no, I was not inclined to keep them around. 825 00:38:39,343 --> 00:38:41,510 I was just surprised somebody didn't want them. 826 00:38:44,260 --> 00:38:45,570 Well, actually now I can go back to 827 00:38:45,570 --> 00:38:47,302 gas masks for a minute. 828 00:38:51,120 --> 00:38:54,950 You've read about the tension between Noyes and Walker, 829 00:38:54,950 --> 00:38:56,410 Walker finally leaving. 830 00:38:56,410 --> 00:38:59,410 My grandfather finally becoming head of the chemical 831 00:38:59,410 --> 00:39:01,300 engineering department in 1920, 832 00:39:01,300 --> 00:39:03,630 known as Walker's protege. 833 00:39:03,630 --> 00:39:08,360 But also the real appreciation for the science-based 834 00:39:08,360 --> 00:39:09,060 engineering. 835 00:39:09,060 --> 00:39:12,920 And the more I read Servos's article, the more I would love 836 00:39:12,920 --> 00:39:17,670 to look at his headship of Course 10 in that period. 837 00:39:17,670 --> 00:39:20,240 I think it's a really interesting story. 838 00:39:20,240 --> 00:39:20,750 I don't know it. 839 00:39:20,750 --> 00:39:24,176 But I'm almost sure it's there. 840 00:39:24,176 --> 00:39:29,000 OK, he it comes back. 841 00:39:29,000 --> 00:39:31,810 Heads the department for 10 years, but that isn't what he 842 00:39:31,810 --> 00:39:32,400 wants to do. 843 00:39:32,400 --> 00:39:34,590 He's not an administrative type. 844 00:39:34,590 --> 00:39:36,030 He doesn't like it. 845 00:39:36,030 --> 00:39:39,550 He loves teaching and he's famous for his teaching. 846 00:39:39,550 --> 00:39:42,770 And that's where he really made his mark. 847 00:39:42,770 --> 00:39:45,490 But he did a lot of consulting for what was what was then 848 00:39:45,490 --> 00:39:49,640 Standard Oil in New Jersey, Esso, Exxon. 849 00:39:49,640 --> 00:39:53,500 And one thing your articles didn't mention I think is the 850 00:39:53,500 --> 00:39:58,160 relationship between the university and industry 851 00:39:58,160 --> 00:40:00,930 through consulting work and how that 852 00:40:00,930 --> 00:40:02,880 fits into the picture. 853 00:40:02,880 --> 00:40:05,850 And he was a great believer in the value of consulting. 854 00:40:05,850 --> 00:40:09,890 That's how you find out what's happening in the world and it 855 00:40:09,890 --> 00:40:10,880 keeps you on your toes. 856 00:40:10,880 --> 00:40:12,820 And it's also useful for industry. 857 00:40:12,820 --> 00:40:19,330 So he, to his death, he got a check every month from Exxon. 858 00:40:19,330 --> 00:40:22,170 I mean it wasn't a lot, but it was a retainer. 859 00:40:22,170 --> 00:40:23,540 And he died at what, 94. 860 00:40:23,540 --> 00:40:27,740 So they were very loyal to him and vice versa. 861 00:40:27,740 --> 00:40:35,480 So this is a drawing of the catalytic cracking process. 862 00:40:35,480 --> 00:40:37,405 Let's see, have you been to the MIT Museum exhibit? 863 00:40:37,405 --> 00:40:38,120 You must have been. 864 00:40:38,120 --> 00:40:38,500 AUDIENCE: I have. 865 00:40:38,500 --> 00:40:39,990 ROSALIND WILLIAMS: OK. 866 00:40:39,990 --> 00:40:40,985 And you go through the whole thing. 867 00:40:40,985 --> 00:40:43,660 And just when you're going to leave when to go out of the 868 00:40:43,660 --> 00:40:50,820 exhibit in that back room, on the left, is a picture of my 869 00:40:50,820 --> 00:40:54,410 grandfather and a couple other gentlemen at a refinery in 870 00:40:54,410 --> 00:41:00,080 Venezuela where catalytic cracking has been put into 871 00:41:00,080 --> 00:41:02,000 production in 1939. 872 00:41:02,000 --> 00:41:05,030 And there's a barrel above there, an 873 00:41:05,030 --> 00:41:06,070 empty barrel I trust. 874 00:41:06,070 --> 00:41:08,120 But anyway, just to make the exhibit 875 00:41:08,120 --> 00:41:10,090 about catalytic cracking. 876 00:41:10,090 --> 00:41:14,720 But the timing, 1939, means that once the war broke out in 877 00:41:14,720 --> 00:41:19,200 1940, the demand for aviation fuel was huge. 878 00:41:19,200 --> 00:41:22,740 I mean catalytic cracking began as a way to get higher 879 00:41:22,740 --> 00:41:24,365 octane for automobiles. 880 00:41:24,365 --> 00:41:27,440 And it was the automobile race that instigated it. 881 00:41:27,440 --> 00:41:30,730 AUDIENCE: Does everybody know what catalytic cracking is? 882 00:41:30,730 --> 00:41:34,130 ROSALIND WILLIAMS: So let me give my brief, nontechnical-- 883 00:41:34,130 --> 00:41:35,670 actually this is very interesting. 884 00:41:35,670 --> 00:41:39,330 He did the work in the basement of Building 12. 885 00:41:39,330 --> 00:41:46,120 And you need some kind of a catalytic agent 886 00:41:46,120 --> 00:41:48,560 to promote the cracking. 887 00:41:48,560 --> 00:41:54,690 It's usually a powder and its mixed in with the petroleum to 888 00:41:54,690 --> 00:41:58,730 get more higher octane fractions or lighter weight 889 00:41:58,730 --> 00:42:01,440 fractions out of a certain amount of petroleum. 890 00:42:01,440 --> 00:42:04,420 So if you have the same amount of petroleum and the cracking 891 00:42:04,420 --> 00:42:07,430 works efficiently, you get more usable high octane fuel 892 00:42:07,430 --> 00:42:08,560 than you do without it. 893 00:42:08,560 --> 00:42:10,000 So you have this-- 894 00:42:10,000 --> 00:42:12,588 AUDIENCE: You take crude oil, basically, and separating out 895 00:42:12,588 --> 00:42:13,381 all the parts. 896 00:42:13,381 --> 00:42:16,330 ROSALIND WILLIAMS: It's part of the distillation process. 897 00:42:16,330 --> 00:42:19,870 And a higher octane means you can run engines faster and get 898 00:42:19,870 --> 00:42:23,112 more power out of them, without knocking and so forth. 899 00:42:23,112 --> 00:42:25,880 You know when you need higher octane, if you fill up your 900 00:42:25,880 --> 00:42:28,320 car and your car starts knocking. 901 00:42:28,320 --> 00:42:30,000 That's a sign that things are not going well. 902 00:42:30,000 --> 00:42:31,090 It's true in cars. 903 00:42:31,090 --> 00:42:32,410 It's true in airplanes. 904 00:42:32,410 --> 00:42:38,850 So they were trying to blow the catalyst through the 905 00:42:38,850 --> 00:42:41,170 petroleum stream. 906 00:42:41,170 --> 00:42:44,070 But as a pattern, it kept settling out. 907 00:42:44,070 --> 00:42:47,340 It didn't stay mixed in with the stream. 908 00:42:47,340 --> 00:42:50,110 So after months and months of work, on trying to get it to 909 00:42:50,110 --> 00:42:53,640 hold into the stream, my grandfather, who was famously 910 00:42:53,640 --> 00:42:58,000 profane, said damn it, let it settle out. 911 00:42:58,000 --> 00:43:01,060 And in other words, if you let it settle out, then you get a 912 00:43:01,060 --> 00:43:04,480 fluid bed at kind of the bottom of the reactor. 913 00:43:04,480 --> 00:43:09,360 And it mixes the fumes, the petroleum fumes with, or 914 00:43:09,360 --> 00:43:13,165 gases, with the catalyst, better than if you try to blow 915 00:43:13,165 --> 00:43:15,360 it along with the stream. 916 00:43:15,360 --> 00:43:20,320 So it's fluid-bed catalytic cracking that he and his 917 00:43:20,320 --> 00:43:25,330 students are known for and brought a huge fortune to 918 00:43:25,330 --> 00:43:28,300 Exxon, which is one of the early adopters. 919 00:43:28,300 --> 00:43:31,050 What he never imagined was that-- 920 00:43:31,050 --> 00:43:33,150 again, it comes on line in 1939. 921 00:43:33,150 --> 00:43:38,030 Within a year, the tankers are going to Venezuela to fill up 922 00:43:38,030 --> 00:43:41,500 with a high octane aviation fuel, going to the docks of 923 00:43:41,500 --> 00:43:44,050 Liverpool, and pumping the fuel into 924 00:43:44,050 --> 00:43:46,080 the tanks of Spitfires. 925 00:43:46,080 --> 00:43:48,740 They don't even put it in the holding tank. 926 00:43:48,740 --> 00:43:52,670 They put it right in the tanks of the airplanes. 927 00:43:52,670 --> 00:43:54,830 And the Spitfires go up to do battle in 928 00:43:54,830 --> 00:43:56,760 the Battle of Britain. 929 00:43:56,760 --> 00:44:04,040 So it's a dramatic example of what you do and then how 930 00:44:04,040 --> 00:44:08,240 things happen to change the implications of what you do, 931 00:44:08,240 --> 00:44:10,290 that are entirely out of your control. 932 00:44:10,290 --> 00:44:12,580 That of course is also the story of 933 00:44:12,580 --> 00:44:13,830 the Manhattan Project. 934 00:44:17,050 --> 00:44:20,060 When the Manhattan Project got under way-- 935 00:44:20,060 --> 00:44:22,030 do I have any slides about this? 936 00:44:22,030 --> 00:44:23,540 Oh, this goes back, OK-- 937 00:44:28,290 --> 00:44:33,710 basically my grandfather is asked to head up the series of 938 00:44:33,710 --> 00:44:38,530 committees making recommendations about the 939 00:44:38,530 --> 00:44:42,950 extraction and refinement of fissionable material. 940 00:44:42,950 --> 00:44:46,660 In other words, the chemical engineering problems of the 941 00:44:46,660 --> 00:44:52,590 atomic weapons, they require high grade ore, high grade 942 00:44:52,590 --> 00:44:54,220 uranium or plutonium. 943 00:44:54,220 --> 00:44:55,220 And how do you get it? 944 00:44:55,220 --> 00:44:56,690 That's an engineering problem. 945 00:44:56,690 --> 00:44:58,450 That's a chemical engineering problem. 946 00:44:58,450 --> 00:45:03,446 So if you go to the MIT archives and ask for Warren K. 947 00:45:03,446 --> 00:45:07,376 Lewis material, a lot of it is still classified from World 948 00:45:07,376 --> 00:45:10,460 War II, but there is a notebook that he kept when he 949 00:45:10,460 --> 00:45:13,760 was going around to, trying to figure out-- 950 00:45:13,760 --> 00:45:16,100 I think this is 1941. 951 00:45:16,100 --> 00:45:20,110 When was the chain reaction started? '42, right, in Stagg 952 00:45:20,110 --> 00:45:21,070 Field, Chicago? 953 00:45:21,070 --> 00:45:22,010 AUDIENCE: Chicago? 954 00:45:22,010 --> 00:45:22,370 ROSALIND WILLIAMS: Chicago. 955 00:45:22,370 --> 00:45:23,040 Was that earlier? 956 00:45:23,040 --> 00:45:23,540 AUDIENCE: Earlier. 957 00:45:23,540 --> 00:45:24,075 ROSALIND WILLIAMS: It was earlier. 958 00:45:24,075 --> 00:45:26,340 AUDIENCE: Before the war I think. 959 00:45:26,340 --> 00:45:27,820 ROSALIND WILLIAMS: In the middle of this notebook, 960 00:45:27,820 --> 00:45:29,420 appears that event. 961 00:45:29,420 --> 00:45:32,030 And he's going around to DuPont, to Oak Ridge. 962 00:45:32,030 --> 00:45:35,500 He's going out to Berkeley, Lawrence Lab, talking to all 963 00:45:35,500 --> 00:45:40,600 these people, trying to figure out how to do the refining to 964 00:45:40,600 --> 00:45:44,400 get the material that they would need for these weapons. 965 00:45:44,400 --> 00:45:46,650 And he served on a series of committees. 966 00:45:46,650 --> 00:45:53,550 Was gone all during the war, kind of overseeing the 967 00:45:53,550 --> 00:45:56,790 construction and the development of these vast 968 00:45:56,790 --> 00:46:00,872 facilities, especially at Oak Ridge, also out in Hanford. 969 00:46:00,872 --> 00:46:04,560 AUDIENCE: If you look at the Manhattan Project, which my 970 00:46:04,560 --> 00:46:07,194 favorite statistics would be the size of the US auto 971 00:46:07,194 --> 00:46:11,200 industry at the time, a huge project, less that 10% of it 972 00:46:11,200 --> 00:46:14,960 is concentrated at Los Alamos or [INAUDIBLE]. 973 00:46:14,960 --> 00:46:16,468 Brilliant physicists are-- 974 00:46:16,468 --> 00:46:19,610 and most of it were chemical engineering plants in 975 00:46:19,610 --> 00:46:24,362 Tennessee and in Washington state, huge plants making the 976 00:46:24,362 --> 00:46:27,050 actual material. 977 00:46:27,050 --> 00:46:32,390 ROSALIND WILLIAMS: So he told his wife, my grandmother, just 978 00:46:32,390 --> 00:46:33,410 don't ask where I am. 979 00:46:33,410 --> 00:46:37,410 But if you need me in an emergency, you call General 980 00:46:37,410 --> 00:46:41,220 Groves in Washington, and gave her the phone number. 981 00:46:41,220 --> 00:46:45,350 And again, I presume the students have already heard 982 00:46:45,350 --> 00:46:48,850 this, but my mother was married in 1940 and 983 00:46:48,850 --> 00:46:50,210 I was born in 1944. 984 00:46:50,210 --> 00:46:51,570 So this was kind of like the next 985 00:46:51,570 --> 00:46:53,390 generation was coming along. 986 00:46:53,390 --> 00:46:56,807 And my mother tells me that when she heard the Lowell 987 00:46:56,807 --> 00:46:59,620 Thomas announcement of the bomb being dropped on 988 00:46:59,620 --> 00:47:03,780 Hiroshima, on the radio, she said now I know where pop's 989 00:47:03,780 --> 00:47:06,490 been, all the war. 990 00:47:06,490 --> 00:47:09,380 And I'm a baby. 991 00:47:09,380 --> 00:47:15,650 And we're back to Japan these days. 992 00:47:15,650 --> 00:47:22,335 OK, I have to think he was deeply troubled by his role in 993 00:47:22,335 --> 00:47:24,730 the Manhattan Project because he didn't talk about it. 994 00:47:24,730 --> 00:47:27,340 He talked a lot about World War I and gas masks. 995 00:47:27,340 --> 00:47:30,360 But World War II, he just-- 996 00:47:30,360 --> 00:47:34,400 I mean I wish I had pressed him more, but I didn't. 997 00:47:34,400 --> 00:47:36,850 My mother said that after the war-- 998 00:47:36,850 --> 00:47:40,630 for example, at those days if you got a watch, a wrist 999 00:47:40,630 --> 00:47:42,820 watch, and you wanted it to glow in the dark, they put a 1000 00:47:42,820 --> 00:47:46,460 little radium on the dial just to make it glow in the dark. 1001 00:47:46,460 --> 00:47:48,320 And he would scrape it off. 1002 00:47:48,320 --> 00:47:51,980 He didn't want any of that stuff near him. 1003 00:47:51,980 --> 00:47:54,480 Anyway, so I'm surmising. 1004 00:47:54,480 --> 00:47:58,830 But he chaired the Lewis committee, and you'll hear a 1005 00:47:58,830 --> 00:48:01,460 lot more about that, kept teaching at MIT. 1006 00:48:01,460 --> 00:48:05,830 My husband had him as a kind of senior thesis adviser in 1007 00:48:05,830 --> 00:48:09,000 the early 1960s. 1008 00:48:09,000 --> 00:48:14,450 And there's a lot of letters that he wrote about the role 1009 00:48:14,450 --> 00:48:17,040 of the engineer and civilization, the profession 1010 00:48:17,040 --> 00:48:19,360 of engineering. 1011 00:48:19,360 --> 00:48:22,090 And this quote from the Lewis Report I 1012 00:48:22,090 --> 00:48:23,700 think really captures-- 1013 00:48:23,700 --> 00:48:26,285 I mean we don't know who actually wrote it. 1014 00:48:26,285 --> 00:48:28,640 Maybe it Morrison or somebody. 1015 00:48:28,640 --> 00:48:30,850 But he really believes that. 1016 00:48:30,850 --> 00:48:37,930 He said, if I could come back, it would be as a social 1017 00:48:37,930 --> 00:48:41,470 scientist, because that's where the big problems are, 1018 00:48:41,470 --> 00:48:43,050 the really intractable ones. 1019 00:48:43,050 --> 00:48:45,790 I can see after World War II why you would say that. 1020 00:48:45,790 --> 00:48:49,280 So that's the-- 1021 00:48:49,280 --> 00:48:51,680 yeah, the Spring Garden farm again. 1022 00:48:51,680 --> 00:48:52,910 OK, so back to the farm. 1023 00:48:52,910 --> 00:49:01,610 So what I did in about 15 minutes before class was just 1024 00:49:01,610 --> 00:49:03,240 go through my box of stuff. 1025 00:49:03,240 --> 00:49:05,800 And I'm just going to pass this around. 1026 00:49:05,800 --> 00:49:08,850 Obviously, just collect it back there, when it 1027 00:49:08,850 --> 00:49:10,920 gets back to you. 1028 00:49:10,920 --> 00:49:13,240 The point is what you learn from archives that you don't 1029 00:49:13,240 --> 00:49:17,300 learn from reading articles or so forth. 1030 00:49:17,300 --> 00:49:20,380 Monthly Report, Laurel City Schools, Laurel, Delaware, 1031 00:49:20,380 --> 00:49:23,560 Report of Warren Lewis, 1895. 1032 00:49:23,560 --> 00:49:26,740 This tells you sort of, not only what his grades are, but 1033 00:49:26,740 --> 00:49:27,350 what they're teaching. 1034 00:49:27,350 --> 00:49:28,570 PROFESSOR: Is that the original document? 1035 00:49:28,570 --> 00:49:29,740 ROSALIND WILLIAMS: That's the document. 1036 00:49:29,740 --> 00:49:31,200 Why do I have this stuff? 1037 00:49:31,200 --> 00:49:33,488 I have no idea. 1038 00:49:33,488 --> 00:49:37,130 I gave a lot of it to the archives. 1039 00:49:37,130 --> 00:49:38,610 And they have copies of this. 1040 00:49:38,610 --> 00:49:40,850 And I kept a few original documents. 1041 00:49:40,850 --> 00:49:42,060 There's a lot more. 1042 00:49:42,060 --> 00:49:44,840 I mean I am from a very literate family. 1043 00:49:44,840 --> 00:49:46,620 I don't know how else to put it. 1044 00:49:46,620 --> 00:49:50,080 Now Ross Basset told you about going through MIT yearbooks 1045 00:49:50,080 --> 00:49:52,863 and looking at where people are from? 1046 00:49:52,863 --> 00:49:54,760 PROFESSOR: A little bit. 1047 00:49:54,760 --> 00:49:57,230 ROSALIND WILLIAMS: This is my grandfather on the left. 1048 00:49:57,230 --> 00:50:03,320 So this is what Ross was looking at, hometown and list. 1049 00:50:03,320 --> 00:50:05,660 My grandfather's list is very brief. 1050 00:50:05,660 --> 00:50:09,430 But again, I just thought you'd like to see. 1051 00:50:09,430 --> 00:50:14,780 And Breslau, here are photographs of Breslau, where 1052 00:50:14,780 --> 00:50:19,690 he studied, got his Ph.D. I mean it got bombed to 1053 00:50:19,690 --> 00:50:20,670 smithereens in the war. 1054 00:50:20,670 --> 00:50:22,370 None of this is here anymore. 1055 00:50:22,370 --> 00:50:26,870 But this is old Germany. 1056 00:50:26,870 --> 00:50:29,730 PROFESSOR: Did you ever go back to try to visit there? 1057 00:50:29,730 --> 00:50:33,330 ROSALIND WILLIAMS: Not Breslau, no. 1058 00:50:33,330 --> 00:50:35,100 I think it blew all to smithereens. 1059 00:50:35,100 --> 00:50:36,360 PROFESSOR: Probably nothing to see. 1060 00:50:36,360 --> 00:50:38,040 ROSALIND WILLIAMS: And I had a couple of bigger photos, that 1061 00:50:38,040 --> 00:50:40,800 are really beauties, that I have framed it at home. 1062 00:50:40,800 --> 00:50:42,255 And here's his dissertation. 1063 00:50:42,255 --> 00:50:47,210 I'm not sure, my German not being workable. 1064 00:50:47,210 --> 00:50:52,080 But it's signed Rosalind D. Kenway, from Warren, July '05, 1065 00:50:52,080 --> 00:50:53,330 that's my grandmother. 1066 00:50:58,740 --> 00:51:02,410 The Tech, special chemistry and chemical engineering 1067 00:51:02,410 --> 00:51:05,030 issue, 1910. 1068 00:51:05,030 --> 00:51:08,720 So remember that chart showing chemistry is going down and 1069 00:51:08,720 --> 00:51:10,650 chemical-- so this is published at that time. 1070 00:51:10,650 --> 00:51:15,070 I have no idea why I have this, but I do. 1071 00:51:15,070 --> 00:51:18,580 And it's so interesting. 1072 00:51:18,580 --> 00:51:21,470 Few industries not founded on chemistry, it says. 1073 00:51:24,610 --> 00:51:25,880 Now, this is a Xerox. 1074 00:51:25,880 --> 00:51:30,840 This is his father basically selling off the stock of the 1075 00:51:30,840 --> 00:51:34,220 farm, public sale of valuable cows. 1076 00:51:34,220 --> 00:51:37,830 And this is what his father writes in 1917, back in 1077 00:51:37,830 --> 00:51:38,930 Laurel, Delaware. 1078 00:51:38,930 --> 00:51:42,870 I have sailed life's storm-swept sea for 74 years 1079 00:51:42,870 --> 00:51:44,880 and I am now nearing port. 1080 00:51:44,880 --> 00:51:46,430 I smell the land. 1081 00:51:46,430 --> 00:51:49,430 It is wise that I should take in-- and I can't read it. 1082 00:51:49,430 --> 00:51:51,710 But it must be take in the sails-- 1083 00:51:51,710 --> 00:51:53,250 Therefore on-- 1084 00:51:53,250 --> 00:51:55,790 He's going to sell his milk cows. 1085 00:51:55,790 --> 00:51:58,610 This is the start of the decline of agriculture in the 1086 00:51:58,610 --> 00:52:03,350 United States right here, the family farm. 1087 00:52:03,350 --> 00:52:07,760 This is the high school, now Newton North, Newton high 1088 00:52:07,760 --> 00:52:13,360 school kind of review magazine. 1089 00:52:13,360 --> 00:52:14,490 This is 1918. 1090 00:52:14,490 --> 00:52:17,730 A lot of young men are going over to Europe. 1091 00:52:17,730 --> 00:52:22,490 But it talks about a Newton high school scientist. 1092 00:52:22,490 --> 00:52:25,320 Of the many capable men on the defense side of chemical 1093 00:52:25,320 --> 00:52:28,450 warfare service, perhaps none has contributed more practical 1094 00:52:28,450 --> 00:52:30,050 ideas that Dr. Lewis. 1095 00:52:30,050 --> 00:52:33,510 This is his high school, hall of fame, kind of. 1096 00:52:33,510 --> 00:52:34,760 This is page 10. 1097 00:52:37,870 --> 00:52:40,150 My kids went to the same school. 1098 00:52:40,150 --> 00:52:41,306 PROFESSOR: Newton North? 1099 00:52:41,306 --> 00:52:43,170 ROSALIND WILLIAMS: Yeah, of course. 1100 00:52:43,170 --> 00:52:44,465 OK, this is March 5, 1920. 1101 00:52:44,465 --> 00:52:45,715 PROFESSOR: Of course. 1102 00:52:49,010 --> 00:52:50,060 ROSALIND WILLIAMS: You got to show spirit. 1103 00:52:50,060 --> 00:52:51,660 PROFESSOR: Of course. 1104 00:52:51,660 --> 00:52:53,527 Boy if live in Newton, there's a difference. 1105 00:52:53,527 --> 00:52:53,880 I know that. 1106 00:52:53,880 --> 00:52:54,050 ROSALIND WILLIAMS: A different Newton. 1107 00:52:54,050 --> 00:52:56,410 It matters whether it's north or south. 1108 00:52:56,410 --> 00:53:02,170 OK, Debbie K.

Do you remember that article, 1264 01:00:31,840 --> 01:00:35,070 about the importance of artifacts in the study of 1265 01:00:35,070 --> 01:00:37,830 technology particularly? 1266 01:00:37,830 --> 01:00:40,330 ROSALIND WILLIAMS: The story is that they had four 1267 01:00:40,330 --> 01:00:42,570 children, two daughters, two sons. 1268 01:00:42,570 --> 01:00:49,280 The other daughter, besides my mother, Mary, married a guy 1269 01:00:49,280 --> 01:00:52,140 named Cherry Emerson, who went into plastics 1270 01:00:52,140 --> 01:00:54,390 after World War II. 1271 01:00:54,390 --> 01:00:57,150 Plastics, and to quote Chambers, made quite a bit of 1272 01:00:57,150 --> 01:01:00,220 money in chemical engineering. 1273 01:01:00,220 --> 01:01:02,630 And he studied with Doc during the war. 1274 01:01:02,630 --> 01:01:07,940 So he gave the money to renovate the library, naming 1275 01:01:07,940 --> 01:01:12,780 it in honor of my grandmother, Warren K Lewis' wife. 1276 01:01:12,780 --> 01:01:15,780 And he always claimed it was because she 1277 01:01:15,780 --> 01:01:17,180 loved music so much. 1278 01:01:17,180 --> 01:01:20,345 And I must say I never heard her listen 1279 01:01:20,345 --> 01:01:22,320 or talk about music. 1280 01:01:22,320 --> 01:01:24,830 So I think it was more Cherry's love 1281 01:01:24,830 --> 01:01:26,110 of music, than her's. 1282 01:01:26,110 --> 01:01:27,010 But that doesn't matter. 1283 01:01:27,010 --> 01:01:30,770 I think it's a great library. 1284 01:01:30,770 --> 01:01:35,610 And I think my grandmother would particularly be happy 1285 01:01:35,610 --> 01:01:37,780 that students can sleep on the couches there. 1286 01:01:37,780 --> 01:01:40,420 She's a very gentle soul. 1287 01:01:46,290 --> 01:01:50,031 AUDIENCE: Does anybody

01:02:00,180 this long has this kind of family connection. 1291 01:02:00,180 --> 01:02:03,429 Universities are sort of famous for keeping track of 1292 01:02:03,429 --> 01:02:04,679 that sort of thig. 1293 01:02:10,180 --> 01:02:12,170 And that's true among faculty, as well. 1294 01:02:12,170 --> 01:02:17,560 And there's the genealogies of our blood families. 1295 01:02:17,560 --> 01:02:20,110 And then we'll talk a bit about this, but not to much 1296 01:02:20,110 --> 01:02:20,950 explicitly yet. 1297 01:02:20,950 --> 01:02:23,795 We'll talk about it in the second half, the academic 1298

student. 1301 01:02:29,564 --> 01:02:34,530 And then our colleague, Leo Marx, who was my teacher, Who 1302 01:02:34,530 --> 01:02:36,910 said that, how does it go? 1303 01:02:36,910 --> 01:02:39,801 His adviser from Harvard in the '40s-- it's only two steps 1304 01:02:39,801 --> 01:02:42,687 back to Ralph Waldo Emerson. 1305 01:02:42,687 --> 01:02:45,332 You can trace four academic generations today from Leo 1306 01:02:45,332 --> 01:02:47,016 Marx to Ralph Waldo Emerson. 1307 01:02:51,950 --> 01:02:55,060 I'm sure there are people here, some of the senior 1308 01:02:55,060 --> 01:02:57,960 faculty who were students of your grandfather's. 1309 01:02:57,960 --> 01:02:59,320 ROSALIND WILLIAMS: If I go to Chemical 1310 01:02:59,320 --> 01:03:00,810 Engineering, they just-- 1311 01:03:00,810 --> 01:03:02,060 oh, Warren K-- 1312 01:03:05,210 --> 01:03:07,910 AUDIENCE: And that's a person who started here in 1896. 1313 01:03:07,910 --> 01:03:11,347 And more than 100 years later, there are still that person's 1314 01:03:11,347 --> 01:03:12,820 students around. 1315 01:03:12,820 --> 01:03:14,680 ROSALIND WILLIAMS: That's been a great been pleasure of 1316 01:03:14,680 --> 01:03:15,410 university life. 1317 01:03:15,410 --> 01:03:16,245 It's a sense of continuity. 1318 01:03:16,245 --> 01:03:17,950 I mean it would drive me crazy too. 1319 01:03:22,710 --> 01:03:27,870 PROFESSOR: Ros, your grandfather was born in 1320 01:03:27,870 --> 01:03:31,920 Delaware and pretty much raised there. 1321 01:03:31,920 --> 01:03:35,500 He obviously was a religious person. 1322 01:03:35,500 --> 01:03:36,750 What persuasion? 1323 01:03:39,230 --> 01:03:41,750 ROSALIND WILLIAMS: I think in Delaware, he was Methodist. 1324 01:03:41,750 --> 01:03:42,080 PROFESSOR: Methodist. 1325 01:03:42,080 --> 01:03:42,910 Yeah, that makes sense. 1326 01:03:42,910 --> 01:03:45,560 ROSALIND WILLIAMS: And one of the most fascinating books I 1327 01:03:45,560 --> 01:03:49,130 have is of an uncle of his who was a Methodist circuit rider 1328 01:03:49,130 --> 01:03:54,800 in Delaware, in the 1850s, setting up black churches. 1329 01:03:54,800 --> 01:03:55,490 They were separate,-- 1330 01:03:55,490 --> 01:03:55,690 PROFESSOR: Really. 1331 01:03:55,690 --> 01:03:56,400 ROSALIND WILLIAMS: --but setting them up. 1332 01:03:56,400 --> 01:03:58,670 Oh, it's fascinating. 1333 01:03:58,670 --> 01:04:02,810 And my grandfather then joined the Congregational church up 1334 01:04:02,810 --> 01:04:07,620 here, Elliott church in Newton. 1335 01:04:07,620 --> 01:04:10,650 Because Methodism up here is a little different from what it 1336 01:04:10,650 --> 01:04:12,100 was in the South. 1337 01:04:12,100 --> 01:04:13,820 But you get the point. 1338 01:04:13,820 --> 01:04:14,650 It's a low church. 1339 01:04:14,650 --> 01:04:15,900 It's not Episcopalian. 1340 01:04:18,181 --> 01:04:22,560 And he taught Sunday school every Sunday, 1341 01:04:22,560 --> 01:04:24,380 as long as he could. 1342 01:04:24,380 --> 01:04:28,910 And his religious faith meant a lot to him. 1343 01:04:28,910 --> 01:04:31,820 He was not a fundamentalist, at all. 1344 01:04:31,820 --> 01:04:36,910 He said, I take the Bible seriously, but not literally. 1345 01:04:36,910 --> 01:04:41,450 But I mean he knew his Bible up one side 1346 01:04:41,450 --> 01:04:43,270 and down the other. 1347 01:04:43,270 --> 01:04:45,890 And it was really fundamental to him. 1348 01:04:45,890 --> 01:04:52,075 In his old age, he became good friends with John Crocker, who 1349 01:04:52,075 --> 01:04:57,080 was the Episcopal chaplain here at MIT. 1350 01:04:57,080 --> 01:04:58,410 And they had a lot of talks. 1351 01:04:58,410 --> 01:05:00,780 And I mean again, I think maybe whether it was guilt 1352 01:05:00,780 --> 01:05:08,640 about the Manhattan Project or just trying to kind of talk 1353 01:05:08,640 --> 01:05:11,280 about matters of faith and other matters too. 1354 01:05:11,280 --> 01:05:18,490 So Crocker led his funeral service, which I was glad that 1355 01:05:18,490 --> 01:05:19,330 he was able to do. 1356 01:05:19,330 --> 01:05:22,110 So I think religion is one of the great untapped kind of 1357 01:05:22,110 --> 01:05:27,750 untapped, unappreciated sources of motivation at MIT. 1358 01:05:27,750 --> 01:05:30,470 And I don't think my grandfather's unusual. 1359 01:05:30,470 --> 01:05:33,480 And it's not necessarily any particular religion. 1360 01:05:33,480 --> 01:05:37,950 But people from outside MIT are always amazed to find how 1361 01:05:37,950 --> 01:05:42,150 strong the religious groups are here and how many there 1362 01:05:42,150 --> 01:05:44,250 are and how active they are. 1363 01:05:44,250 --> 01:05:48,410 It's not their vision of MIT, but it's very true. 1364 01:05:53,450 --> 01:05:53,820 OK. 1365 01:05:53,820 --> 01:05:55,410 ROSALIND WILLIAMS: Well, thank you very much. 1366 01:05:55,410 --> 01:05:57,630 PROFESSOR: Thank you very much. 1367 01:05:57,630 --> 01:06:03,060 PROFESSOR: OK, I want to just talk today a little bit more 1368 01:06:03,060 --> 01:06:06,520 about the '30s, the '20s and the '30s. 1369 01:06:06,520 --> 01:06:12,830 And again, kind of like Ros's talk, use a specific case of a 1370 01:06:12,830 --> 01:06:16,190 particular faculty member and a particular machine to 1371 01:06:16,190 --> 01:06:20,890 illustrate some of the general ideas about where MIT moved 1372 01:06:20,890 --> 01:06:26,790 between about 1925 and 1935 and why that's interesting. 1373 01:06:26,790 --> 01:06:31,850 And you of course know from the readings, and the more you 1374 01:06:31,850 --> 01:06:34,340 look at this, everybody says it and the more I read about 1375 01:06:34,340 --> 01:06:37,460 it, the more you really feel like Karl Compton coming here 1376 01:06:37,460 --> 01:06:40,420 in 1930 was a major turning point. 1377 01:06:40,420 --> 01:06:44,310 There was this kind of internal warfare. 1378 01:06:44,310 --> 01:06:49,140 What was the word that Lewis used, hot fights about the 1379 01:06:49,140 --> 01:06:51,120 relation of science and engineering. 1380 01:06:51,120 --> 01:06:54,930 And the Corporation definitely has an opinion about it. 1381 01:06:54,930 --> 01:06:56,290 And one thing they do-- 1382 01:06:56,290 --> 01:06:58,150 they don't have a lot of control over the faculty, but 1383 01:06:58,150 --> 01:07:00,130 they do decide who the president is. 1384 01:07:00,130 --> 01:07:02,510 And so they bring in Karl Compton. 1385 01:07:02,510 --> 01:07:04,110 He's 42 years old-- 1386 01:07:04,110 --> 01:07:07,100 and it probably sounds old to you. 1387 01:07:07,100 --> 01:07:10,030 It sounds young to me-- 1388 01:07:10,030 --> 01:07:11,230 in 1930. 1389 01:07:11,230 --> 01:07:15,530 And one of the young people who was already here was this 1390 01:07:15,530 --> 01:07:17,420 guy then Vannevar Bush, who we've also heard about, and 1391 01:07:17,420 --> 01:07:20,110 we'll hear about a bunch more, who was a young electrical 1392 01:07:20,110 --> 01:07:22,740 engineering professor. 1393 01:07:22,740 --> 01:07:25,370 And he was building this device called a 1394 01:07:25,370 --> 01:07:26,920 differential analyzer. 1395 01:07:26,920 --> 01:07:32,080 And what I want to do today-- this is again, a sort of 1396 01:07:32,080 --> 01:07:35,150 prototype for what a paper topic might be, is to look at 1397 01:07:35,150 --> 01:07:39,160 this instrument and how this instrument was handled and how 1398 01:07:39,160 --> 01:07:42,230 the instrument itself changed as the goals of the 1399 01:07:42,230 --> 01:07:45,870 Institution changed, from the '20s through the '30s. 1400 01:07:45,870 --> 01:07:48,690 So here's Bush and there's the analyzer. 1401 01:07:48,690 --> 01:07:54,960 And when we go to the MIT Museum, one of the 150 objects 1402 01:07:54,960 --> 01:07:56,960 is that part of the analyzer that's in 1403 01:07:56,960 --> 01:07:57,800 the wooden box there. 1404 01:07:57,800 --> 01:07:59,180 I'll tell you more about what that is. 1405 01:07:59,180 --> 01:08:01,405 But it's sitting right there on the front of the floor. 1406 01:08:01,405 --> 01:08:05,380 And when I was first doing this research, I asked them if 1407 01:08:05,380 --> 01:08:07,260 they had a piece of it and they didn't really know. 1408 01:08:07,260 --> 01:08:09,620 And Debbie Douglas and I went back in the storerooms and we 1409 01:08:09,620 --> 01:08:12,535 found that the original integrator was there. 1410 01:08:15,490 --> 01:08:19,050 So if you go into the 1920s, Bush is here. 1411 01:08:19,050 --> 01:08:20,300 He's a young professor. 1412 01:08:20,300 --> 01:08:22,670 He had gotten his Ph.D. here. 1413 01:08:22,670 --> 01:08:24,569 And he was a student of Kennelly, who I mentioned 1414 01:08:24,569 --> 01:08:26,990 before, who was Edison's assistant. 1415 01:08:26,990 --> 01:08:31,720 And they were very much in the kind of technology plan world 1416 01:08:31,720 --> 01:08:36,210 of MIT, solving problems for big industrial partners. 1417 01:08:36,210 --> 01:08:39,100 And what is the problem that the big industrial partners 1418 01:08:39,100 --> 01:08:39,670 are having? 1419 01:08:39,670 --> 01:08:43,040 Well, in the electrical world, and you've got to remember 1420 01:08:43,040 --> 01:08:45,060 electrical engineering for a-- 1421 01:08:45,060 --> 01:08:48,500 how people here are Core 6, in one way or another? 1422 01:08:48,500 --> 01:08:49,859 OK, so about a third. 1423 01:08:49,859 --> 01:08:52,590 Electrical engineering, for its first 100 years, really 1424 01:08:52,590 --> 01:08:56,250 was electrical, without a lot of electronics or any of that 1425 01:08:56,250 --> 01:08:57,899 solid state physics or certainly no 1426 01:08:57,899 --> 01:08:58,779 computers and stuff. 1427 01:08:58,779 --> 01:09:05,410 It was building big machines to make big generators, and 1428 01:09:05,410 --> 01:09:13,399 big generators, transmission lines, large electric motors, 1429 01:09:13,399 --> 01:09:15,520 to drive factories and other kinds of things. 1430 01:09:15,520 --> 01:09:21,450 And anybody ever hear of the IEEE, Institute of Electrical 1431 01:09:21,450 --> 01:09:25,090 and Electronic Engineers? 1432 01:09:25,090 --> 01:09:26,600 This is a little bit of trivia. 1433 01:09:26,600 --> 01:09:29,359 But there was the AIEE, American Institute of 1434 01:09:29,359 --> 01:09:30,240 Electrical Engineers. 1435 01:09:30,240 --> 01:09:32,470 Those are the big electric power people. 1436 01:09:32,470 --> 01:09:35,790 In fact, in German universities they still divide 1437 01:09:35,790 --> 01:09:38,779 the curriculum into big signals and a little signals. 1438 01:09:38,779 --> 01:09:41,819 And so big signals was the AIEE. 1439 01:09:41,819 --> 01:09:44,479 Little signals was the IRE, Institute of Radio 1440 01:09:44,479 --> 01:09:47,710 Engineering, lots of little tiny, little small signals. 1441 01:09:47,710 --> 01:09:50,330 And in 1964, they merged in the IEEE. 1442 01:09:50,330 --> 01:09:52,470 It's to electrical and electronic engineers. 1443 01:09:52,470 --> 01:09:55,520 Even though it's probably one of the two major professional 1444 01:09:55,520 --> 01:09:58,240 societies for computation, but the word "computer" doesn't 1445 01:09:58,240 --> 01:10:01,110 appear in the title at all. 1446 01:10:01,110 --> 01:10:03,970 And so, this is back in the days of electric power. 1447 01:10:03,970 --> 01:10:09,710 And the problem with the electric power industry is the 1448 01:10:09,710 --> 01:10:15,030 electric generators start out as basically local phenomena. 1449 01:10:15,030 --> 01:10:17,840 A local entrepreneur will build a generator, either a 1450 01:10:17,840 --> 01:10:20,000 hydro plant or steam powered, in one way or 1451 01:10:20,000 --> 01:10:22,040 another, in a town. 1452 01:10:22,040 --> 01:10:26,940 And they'll create lighting in the town and maybe run some 1453 01:10:26,940 --> 01:10:28,650 motors in factories. 1454 01:10:28,650 --> 01:10:31,990 And it's all centralized and it was all nonuniform. 1455 01:10:31,990 --> 01:10:34,080 Every town had a different 1456 01:10:34,080 --> 01:10:36,010 voltage, a different frequency. 1457 01:10:36,010 --> 01:10:38,510 Some of them were running on direct current versus 1458 01:10:38,510 --> 01:10:39,390 alternating current. 1459 01:10:39,390 --> 01:10:43,520 These are all big battles they were having at the time. 1460 01:10:43,520 --> 01:10:47,070 But over the course of the teens and the '20s, those 1461 01:10:47,070 --> 01:10:48,750 systems are becoming standardized and they're 1462 01:10:48,750 --> 01:10:51,420 becoming connected into what today we would call grids. 1463 01:10:51,420 --> 01:10:53,590 So they have a big electric power grid. 1464 01:10:53,590 --> 01:10:57,410 And they're not quite national yet, but 1465 01:10:57,410 --> 01:10:59,020 they're very much regional. 1466 01:10:59,020 --> 01:11:03,040 And so in the '20s, General Electric starts to build a big 1467 01:11:03,040 --> 01:11:10,170 grid that brings hydroelectric power from in Canada and also 1468 01:11:10,170 --> 01:11:13,330 from Niagara Falls, through very, very long transmission 1469 01:11:13,330 --> 01:11:16,130 lines, hundreds and hundreds of miles, down into the New 1470 01:11:16,130 --> 01:11:19,250 York City area, which is where most of the population and 1471 01:11:19,250 --> 01:11:21,780 most of the energy usage is from. 1472 01:11:21,780 --> 01:11:24,660 And those lines begin to have problems. 1473 01:11:24,660 --> 01:11:28,420 And the problems are, if you've got either a lightning 1474 01:11:28,420 --> 01:11:31,740 strike at one part of the line, you had a bad electrical 1475 01:11:31,740 --> 01:11:36,090 storm, or even if you had a short circuit and part of the 1476 01:11:36,090 --> 01:11:41,180 grid tripped off and had just to sort of save itself, you'd 1477 01:11:41,180 --> 01:11:43,300 get these transients on the line. 1478 01:11:43,300 --> 01:11:45,530 And the transients would travel great distances. 1479 01:11:45,530 --> 01:11:49,570 They were just like big wave power spikes on the line and 1480 01:11:49,570 --> 01:11:51,250 create blackouts all over the place. 1481 01:11:51,250 --> 01:11:53,790 And there a couple of famous blackouts that happened in the 1482 01:11:53,790 --> 01:11:55,850 early '20s that really caused a big problem. 1483 01:11:55,850 --> 01:12:02,040 So this was like a critical issue about how do you figure 1484 01:12:02,040 --> 01:12:05,410 out, how do you model the performance of these systems 1485 01:12:05,410 --> 01:12:06,990 under this kind of stress? 1486 01:12:06,990 --> 01:12:10,170 And General Electric, and this has come up in the readings in 1487 01:12:10,170 --> 01:12:12,820 places, had a very close relationship with MIT. 1488 01:12:12,820 --> 01:12:15,840 There were a lot of young engineers who would go there, 1489 01:12:15,840 --> 01:12:17,985 what they called on-test, to Schenectady. 1490 01:12:17,985 --> 01:12:20,960 In fact, that's where Ros's father worked. 1491 01:12:20,960 --> 01:12:24,930 I don't if she mention that, Doc Lewis's son went to 1492 01:12:24,930 --> 01:12:27,750 Schenectady and worked for General Electric. 1493 01:12:27,750 --> 01:12:30,660 And then they would come back to MIT sometimes, to get a 1494 01:12:30,660 --> 01:12:32,010 master's degree. 1495 01:12:32,010 --> 01:12:34,920 And they began looking at this problem of how do you 1496 01:12:34,920 --> 01:12:36,420 understand these systems. 1497 01:12:36,420 --> 01:12:40,120 Now, Bush had done earlier work in his career, which was 1498 01:12:40,120 --> 01:12:42,010 also based on this whole idea of modeling. 1499 01:12:42,010 --> 01:12:44,260 I may have mentioned this before where-- 1500 01:12:44,260 --> 01:12:47,010 how many of you have taken an engineering class where you 1501 01:12:47,010 --> 01:12:53,200 use a spring mass damper system and model a RLC 1502 01:12:53,200 --> 01:12:55,200 circuit with it? 1503 01:12:55,200 --> 01:12:56,790 Ring a bell for anybody? 1504 01:12:56,790 --> 01:12:59,660 OK, maybe a few too many times. 1505 01:12:59,660 --> 01:13:01,530 Or, there are other analogies, different kinds 1506 01:13:01,530 --> 01:13:03,510 of hydraulic analogies. 1507 01:13:03,510 --> 01:13:06,170 Well, that whole idea basically comes from the first 1508 01:13:06,170 --> 01:13:08,470 book that Vannevar Bush wrote, which is called Operational 1509 01:13:08,470 --> 01:13:14,680 Circuit Analysis, where first of all he applies a thing 1510 01:13:14,680 --> 01:13:18,860 called Oliver Heaviside's operational calculus. 1511 01:13:18,860 --> 01:13:21,170 Anybody ever heard of the Heaviside step function? 1512 01:13:24,438 --> 01:13:29,360 And Heaviside was a sort of somewhat outlandish English 1513 01:13:29,360 --> 01:13:31,580 engineer around the turn of the century, who came up with 1514 01:13:31,580 --> 01:13:32,710 these ideas. 1515 01:13:32,710 --> 01:13:34,890 Mathematicians didn't like them because they couldn't 1516 01:13:34,890 --> 01:13:36,510 prove they were valid. 1517 01:13:36,510 --> 01:13:38,685 Heaviside just didn't care about it at all because he 1518 01:13:38,685 --> 01:13:40,390 could show that they were useful. 1519 01:13:40,390 --> 01:13:43,760 And they told you a lot about how transients go down lines. 1520 01:13:43,760 --> 01:13:46,390 And Bush really took the Heaviside work and he put it 1521 01:13:46,390 --> 01:13:48,740 on a rigorous mathematical foundation. 1522 01:13:48,740 --> 01:13:51,840 And said among other things, you can use these analogies 1523 01:13:51,840 --> 01:13:57,570 and you can model a second order system in any of these 1524 01:13:57,570 --> 01:14:00,120 different fields with a set of equations. 1525 01:14:00,120 --> 01:14:03,460 And that can be either RLC circuit or a spring mass 1526 01:14:03,460 --> 01:14:07,080 damper or there are also hydraulic versions of it, I'm 1527 01:14:07,080 --> 01:14:09,320 sure any number of other ones. 1528 01:14:09,320 --> 01:14:13,300 And what that basic idea allows you to do is to make 1529 01:14:13,300 --> 01:14:15,270 models of different kinds of circuits. 1530 01:14:15,270 --> 01:14:17,990 And so what they said is here's this 1531 01:14:17,990 --> 01:14:19,060 electric power problem. 1532 01:14:19,060 --> 01:14:23,120 Let's look at this problem and let's build a model of it. 1533 01:14:23,120 --> 01:14:27,300 And what this thing is, is called a network analyzer. 1534 01:14:27,300 --> 01:14:30,630 And this picture is probably about 1927. 1535 01:14:30,630 --> 01:14:34,240 And all it is, is-- well, first thing they make a model 1536 01:14:34,240 --> 01:14:38,630 of just the electric power line between 1537 01:14:38,630 --> 01:14:41,100 Niagara Falls and Boston. 1538 01:14:41,100 --> 01:14:47,770 So there might be a couple of generators on the line in 1539 01:14:47,770 --> 01:14:50,670 Niagara Falls, then there's a long transmission line, then 1540 01:14:50,670 --> 01:14:57,080 there's a whole bunch of different users, and maybe you 1541 01:14:57,080 --> 01:15:00,280 make one circuit that's 50,000 times 1542 01:15:00,280 --> 01:15:02,780 smaller than the original. 1543 01:15:02,780 --> 01:15:06,500 And you use that as a model. 1544 01:15:06,500 --> 01:15:08,250 And anybody know what the big problem 1545 01:15:08,250 --> 01:15:09,500 with that was actually? 1546 01:15:12,850 --> 01:15:16,720 The hardest thing about making these small models was 1547 01:15:16,720 --> 01:15:19,880 measuring the output. 1548 01:15:19,880 --> 01:15:23,250 If you go to the actual electric power system and you 1549 01:15:23,250 --> 01:15:26,240 put a voltmeter on the line, that voltmeter is going to 1550 01:15:26,240 --> 01:15:27,300 load the line by some amount. 1551 01:15:27,300 --> 01:15:29,690 But it's negligible, it really has no impact. 1552 01:15:29,690 --> 01:15:32,130 If you make it 50,000 times smaller, you've still got the 1553 01:15:32,130 --> 01:15:33,280 same voltmeter. 1554 01:15:33,280 --> 01:15:35,380 And you put it on the line and it's the equivalent of like 1555 01:15:35,380 --> 01:15:36,900 putting a whole factory on the line. 1556 01:15:36,900 --> 01:15:39,060 And it affects the performance of it in ways 1557 01:15:39,060 --> 01:15:42,210 that it wouldn't otherwise. 1558 01:15:42,210 --> 01:15:44,750 So it's one thing to make this model. 1559 01:15:44,750 --> 01:15:46,940 And they did that rather successfully and it helped 1560 01:15:46,940 --> 01:15:47,690 them describe. 1561 01:15:47,690 --> 01:15:50,460 And they then reported the results to GE, this is how the 1562 01:15:50,460 --> 01:15:52,420 thing would behave under a lightning strike. 1563 01:15:52,420 --> 01:15:55,080 And these are some strategies you can take to make it a 1564 01:15:55,080 --> 01:15:56,630 little more robust. 1565 01:15:56,630 --> 01:15:58,980 Well, once the word out about that, all these different 1566 01:15:58,980 --> 01:16:00,760 power companies came and said, we would like you 1567 01:16:00,760 --> 01:16:02,340 to model our system. 1568 01:16:02,340 --> 01:16:03,780 And so what did they do? 1569 01:16:03,780 --> 01:16:05,500 Did they constantly build a new one for 1570 01:16:05,500 --> 01:16:06,670 everybody's power system? 1571 01:16:06,670 --> 01:16:07,380 No. 1572 01:16:07,380 --> 01:16:08,690 They built a little set up. 1573 01:16:08,690 --> 01:16:10,680 Actually, I don't even have to draw it, because it's here. 1574 01:16:10,680 --> 01:16:12,610 Where they said OK, we're going to put a bunch of models 1575 01:16:12,610 --> 01:16:15,580 of transmission lines and a bunch of models of generators 1576 01:16:15,580 --> 01:16:17,190 and a bunch of models of other things. 1577 01:16:17,190 --> 01:16:18,930 And they're actually connected together by 1578 01:16:18,930 --> 01:16:20,770 telephone plug boards. 1579 01:16:20,770 --> 01:16:25,130 And you bring your system here and we'll plug it together in 1580 01:16:25,130 --> 01:16:27,710 a certain way, much like a telephone 1581 01:16:27,710 --> 01:16:29,100 operator connects circuits. 1582 01:16:29,100 --> 01:16:30,790 At that time, it was done manually. 1583 01:16:30,790 --> 01:16:32,870 And we'll create this thing. 1584 01:16:32,870 --> 01:16:37,130 And this thing, they actually called it a network computer, 1585 01:16:37,130 --> 01:16:40,400 which is a nice word for it, that comes up later in MIT 1586 01:16:40,400 --> 01:16:42,080 culture, about 50 years later. 1587 01:16:42,080 --> 01:16:44,420 And electric power companies would come here. 1588 01:16:44,420 --> 01:16:48,270 And students would write their theses by designing this 1589 01:16:48,270 --> 01:16:53,560 system and describing it for a particular power company. 1590 01:16:53,560 --> 01:16:55,140 And saying here, I modeled your circuit. 1591 01:16:55,140 --> 01:16:57,520 And this thing actually was around until the 1592 01:16:57,520 --> 01:16:59,490 '50s, it turns out. 1593 01:16:59,490 --> 01:17:02,000 We'll talk about it getting shut down when Gordon Brown 1594 01:17:02,000 --> 01:17:03,120 shut it down. 1595 01:17:03,120 --> 01:17:07,640 But it was again this kind of classic MIT in the 1920s, 1596 01:17:07,640 --> 01:17:12,020 early '30s, model of close relationships with industry, 1597 01:17:12,020 --> 01:17:15,490 solving very particular problems, almost in a literal 1598 01:17:15,490 --> 01:17:16,750 consulting role. 1599 01:17:16,750 --> 01:17:17,910 Tell us what your issue is? 1600 01:17:17,910 --> 01:17:20,560 We'll model it and we'll help you solve the problem. 1601 01:17:20,560 --> 01:17:23,110 So we read a lot about that. 1602 01:17:27,210 --> 01:17:29,750 Then there was another approach, which was to 1603 01:17:29,750 --> 01:17:35,290 calculate the progress of these transients directly. 1604 01:17:35,290 --> 01:17:37,250 And how did they do that? 1605 01:17:37,250 --> 01:17:43,240 Well, they could do it analytically with algebra. 1606 01:17:43,240 --> 01:17:45,430 It was extremely difficult because it was not easy to 1607 01:17:45,430 --> 01:17:46,250 write the equations. 1608 01:17:46,250 --> 01:17:48,430 But it was much easier to build an analog 1609 01:17:48,430 --> 01:17:50,000 computer to model it. 1610 01:17:50,000 --> 01:17:58,580 And it turned out, and you probably recognize this, that 1611 01:17:58,580 --> 01:18:03,960 the integral of the product of two functions 1612 01:18:03,960 --> 01:18:05,380 is a critical piece. 1613 01:18:05,380 --> 01:18:07,850 Today, you find it in all kinds of signals processing 1614 01:18:07,850 --> 01:18:10,500 and convolution algorithms. 1615 01:18:10,500 --> 01:18:14,830 And they said we'll build basically these machines that 1616 01:18:14,830 --> 01:18:17,330 will model the key function of it. 1617 01:18:17,330 --> 01:18:19,930 And this is an early version of it, which is also a 1618 01:18:19,930 --> 01:18:22,590 specific machine modeled to evaluate 1619 01:18:22,590 --> 01:18:23,660 the specific integral. 1620 01:18:23,660 --> 01:18:25,970 They called it a product intergraph. 1621 01:18:25,970 --> 01:18:27,530 And it didn't use equations at all. 1622 01:18:27,530 --> 01:18:30,030 It just took curves in and drew curves out. 1623 01:18:30,030 --> 01:18:32,980 There you can see Bush. 1624 01:18:32,980 --> 01:18:35,560 This is actually the output device, which 1625 01:18:35,560 --> 01:18:37,250 is a watt/hour meter. 1626 01:18:37,250 --> 01:18:38,760 Why would they use a watt/hour meter 1627 01:18:38,760 --> 01:18:40,170 from an electric utility? 1628 01:18:45,290 --> 01:18:47,380 Because a watt/hour meter does the same thing, right. 1629 01:18:47,380 --> 01:18:50,150 It evaluates the integral of the product of the current. 1630 01:18:50,150 --> 01:18:51,910 And the voltage is the amount of power that 1631 01:18:51,910 --> 01:18:53,890 you get billed for. 1632 01:18:53,890 --> 01:18:57,930 So they take this thing and they just stick there. 1633 01:18:57,930 --> 01:19:00,400 And then there's these kind of funky mechanical linkages. 1634 01:19:00,400 --> 01:19:02,210 And there's all these people involved. 1635 01:19:02,210 --> 01:19:03,980 And actually they have big high-power 1636 01:19:03,980 --> 01:19:06,110 resistors, so they use a-- 1637 01:19:06,110 --> 01:19:07,520 anybody want to guess what that thing hanging 1638 01:19:07,520 --> 01:19:10,450 up on the top is? 1639 01:19:10,450 --> 01:19:11,620 AUDIENCE: Radiator. 1640 01:19:11,620 --> 01:19:13,020 PROFESSOR: Close. 1641 01:19:13,020 --> 01:19:13,460 AUDIENCE: Radiator. 1642 01:19:13,460 --> 01:19:16,120 PROFESSOR: It's a radiator, from? 1643 01:19:16,120 --> 01:19:17,020 AUDIENCE: Model T. 1644 01:19:17,020 --> 01:19:19,840 PROFESSOR: It's a radiator from a Model T Ford, that 1645 01:19:19,840 --> 01:19:23,130 they're using to provide cooling water to this machine, 1646 01:19:23,130 --> 01:19:25,540 which evaluates this particular integral for this 1647 01:19:25,540 --> 01:19:27,510 particular electric power problem. 1648 01:19:27,510 --> 01:19:30,930 In fact, some of these are Bush's students. 1649 01:19:30,930 --> 01:19:33,310 This one particularly is a guy named Harold Hazen, who we 1650 01:19:33,310 --> 01:19:34,900 will talk about later. 1651 01:19:34,900 --> 01:19:39,380 In fact, he's also the guy sitting in the middle there, 1652 01:19:39,380 --> 01:19:40,630 in that picture. 1653 01:19:43,670 --> 01:19:44,620 Here's another picture of it. 1654 01:19:44,620 --> 01:19:48,320 You can see the watt/hour meter, just taken right out of 1655 01:19:48,320 --> 01:19:53,080 an electric power measurement facility. 1656 01:19:53,080 --> 01:19:54,700 Again, you sort of work with what you have. 1657 01:19:54,700 --> 01:19:56,140 They were working with electric companies. 1658 01:19:56,140 --> 01:19:58,180 They had these electrical things, a whole bunch of 1659 01:19:58,180 --> 01:20:00,110 different motor and gears and interconnections. 1660 01:20:00,110 --> 01:20:03,770 And this was probably in Building-- 1661 01:20:03,770 --> 01:20:05,050 somewhere in the main group. 1662 01:20:05,050 --> 01:20:06,010 I'm forgetting exactly. 1663 01:20:06,010 --> 01:20:10,210 Building 10, I believe was this lab. 1664 01:20:10,210 --> 01:20:12,460 I liked, you still have the pencil sharpener there. 1665 01:20:12,460 --> 01:20:14,585 This is probably the one part of what was in the lab that 1666 01:20:14,585 --> 01:20:16,590 you might still find in a laboratory today. 1667 01:20:21,030 --> 01:20:22,360 There's a picture of Bush with it. 1668 01:20:22,360 --> 01:20:23,670 You can see he looks pretty young. 1669 01:20:26,780 --> 01:20:31,710 And so there's the first product 1670 01:20:31,710 --> 01:20:33,490 intergraph, is this device. 1671 01:20:33,490 --> 01:20:37,530 And what it does is all those little graph chart holders 1672 01:20:37,530 --> 01:20:41,170 basically, move under these three independent needles. 1673 01:20:41,170 --> 01:20:47,680 And the operators just follow the first two curves and then 1674 01:20:47,680 --> 01:20:51,410 the output plots the integral of those two curves. 1675 01:20:51,410 --> 01:20:53,700 So it's literally a graphical user interface 1676 01:20:53,700 --> 01:20:56,320 for an analog computer. 1677 01:20:56,320 --> 01:20:59,940 And then, they actually bring it up to one more level of 1678 01:20:59,940 --> 01:21:00,690 complication. 1679 01:21:00,690 --> 01:21:03,560 And there's a way that you can make it solve a differential 1680 01:21:03,560 --> 01:21:06,320 equation, as well as just evaluating an integral. 1681 01:21:06,320 --> 01:21:09,070 And so this thing is called the second product intergraph, 1682 01:21:09,070 --> 01:21:10,060 where it's the same kind of thing. 1683 01:21:10,060 --> 01:21:14,340 There's two different pieces and then you can sort of tie 1684 01:21:14,340 --> 01:21:16,420 the output back to the input. 1685 01:21:16,420 --> 01:21:20,510 And this is about where things stood when Karl Compton 1686 01:21:20,510 --> 01:21:22,395 becomes president of MIT. 1687 01:21:22,395 --> 01:21:25,390 And Compton basically says, we're not going to do that 1688 01:21:25,390 --> 01:21:26,380 kind of stuff anymore. 1689 01:21:26,380 --> 01:21:28,410 It's too focused on just one problem. 1690 01:21:28,410 --> 01:21:30,060 It's too simple. 1691 01:21:30,060 --> 01:21:36,760 And Bush responds in a very energetic way. 1692 01:21:36,760 --> 01:21:39,840 And he builds this machine about 1931. 1693 01:21:39,840 --> 01:21:41,530 And this is called the differential analyzer. 1694 01:21:41,530 --> 01:21:45,380 Anybody ever heard of that term before? 1695 01:21:45,380 --> 01:21:51,280 And really it's kind of nothing more than this, but 1696 01:21:51,280 --> 01:21:53,640 made in a fully general purpose way. 1697 01:21:53,640 --> 01:21:57,250 Or like I mentioned before, they did with the simulator, 1698 01:21:57,250 --> 01:22:00,630 they first started building a custom one and then they built 1699 01:22:00,630 --> 01:22:01,790 a general one. 1700 01:22:01,790 --> 01:22:06,430 And what you see here is, these guys here are called 1701 01:22:06,430 --> 01:22:07,140 integrators. 1702 01:22:07,140 --> 01:22:10,540 That's the core of the problem. 1703 01:22:10,540 --> 01:22:12,520 Again, it's primarily an integral thing you're trying 1704 01:22:12,520 --> 01:22:13,900 to evaluate. 1705 01:22:13,900 --> 01:22:16,450 An integrator is nothing more than, they call it a wheel and 1706 01:22:16,450 --> 01:22:18,030 disk integrator. 1707 01:22:18,030 --> 01:22:19,590 There's a disk that spins around. 1708 01:22:19,590 --> 01:22:22,530 In a mechanical sense, that's just a transmission, but a 1709 01:22:22,530 --> 01:22:24,200 continuously variable one. 1710 01:22:24,200 --> 01:22:26,520 Then there's a wheel that sits on the transmission. 1711 01:22:26,520 --> 01:22:32,830 And if the disk is spinning at a fixed rate and the wheel 1712 01:22:32,830 --> 01:22:35,210 goes in and out, the number of turns on the upper end of 1713 01:22:35,210 --> 01:22:39,680 wheel is the integral of the curve of the position of the 1714 01:22:39,680 --> 01:22:40,890 wheel that pulls it off. 1715 01:22:40,890 --> 01:22:44,170 But it's a very simple idea mechanically, very hard to do 1716 01:22:44,170 --> 01:22:46,440 that in a way that is mechanically 1717 01:22:46,440 --> 01:22:48,230 robust and very accurate. 1718 01:22:48,230 --> 01:22:51,550 And that's the piece-- 1719 01:22:51,550 --> 01:22:53,910 actually it was so critical to make it accurate, they covered 1720 01:22:53,910 --> 01:22:55,350 these with those wooden boxes. 1721 01:22:55,350 --> 01:23:01,360 That's the piece that's in the MIT Museum. 1722 01:23:01,360 --> 01:23:03,890 And then there's all these other elements. 1723 01:23:03,890 --> 01:23:05,140 I may have a picture of it. 1724 01:23:11,570 --> 01:23:13,620 So there are all these other elements. 1725 01:23:13,620 --> 01:23:15,790 You can take these integrators and then you have a 1726 01:23:15,790 --> 01:23:19,790 multiplier, which is nothing but a gear that connects one 1727 01:23:19,790 --> 01:23:21,590 rod to another in a ratio. 1728 01:23:21,590 --> 01:23:23,500 And you have these rods that go through the middle. 1729 01:23:23,500 --> 01:23:25,760 They're almost like the bus on a computer. 1730 01:23:25,760 --> 01:23:28,950 And you can connect these things in all different ways 1731 01:23:28,950 --> 01:23:31,880 to evaluate a particular equation. 1732 01:23:31,880 --> 01:23:34,810 In this case, this is just a second order equation for a 1733 01:23:34,810 --> 01:23:36,980 falling body problem. 1734 01:23:36,980 --> 01:23:40,390 But you can mix and match this thing and essentially program 1735 01:23:40,390 --> 01:23:43,860 it by rebuilding it around these connecting rods. 1736 01:23:43,860 --> 01:23:47,690 And so, I'll show you a couple of pictures of the-- 1737 01:23:47,690 --> 01:23:48,940 oops. 1738 01:23:52,890 --> 01:23:55,450 Here is another view of the integrator. 1739 01:23:55,450 --> 01:23:59,370 Here you can see the disk and the little 1740 01:23:59,370 --> 01:24:00,250 wheel that takes off. 1741 01:24:00,250 --> 01:24:02,200 It actually has a real knife edge on it, to 1742 01:24:02,200 --> 01:24:04,310 try to make it accurate. 1743 01:24:04,310 --> 01:24:07,340 One of the real problems with those integrators is that they 1744 01:24:07,340 --> 01:24:09,150 can't drive much of a load. 1745 01:24:09,150 --> 01:24:11,820 If they slip at all, they lose a lot of accuracy. 1746 01:24:11,820 --> 01:24:13,870 So here they have put these things called torque 1747 01:24:13,870 --> 01:24:17,050 amplifiers, which are these very clunky, exotic, kind of 1748 01:24:17,050 --> 01:24:20,000 cached in like devices that amplify the torque. 1749 01:24:20,000 --> 01:24:22,220 And then they connect them in. 1750 01:24:22,220 --> 01:24:26,640 And where you might have in an electrical analog computer, 1751 01:24:26,640 --> 01:24:30,530 there's a voltage that gets pushed around, in a mechanical 1752 01:24:30,530 --> 01:24:34,330 analogue computer it's just the rotation of these shafts 1753 01:24:34,330 --> 01:24:37,070 that carry the data from one place to another. 1754 01:24:37,070 --> 01:24:43,060 And they do that by going into this matrix of mechanical rods 1755 01:24:43,060 --> 01:24:44,410 that you see over there on the left. 1756 01:24:44,410 --> 01:24:47,450 And each time they wanted, they could kind of reprogram 1757 01:24:47,450 --> 01:24:48,600 the whole thing. 1758 01:24:48,600 --> 01:24:50,710 And here's another shot. 1759 01:24:50,710 --> 01:24:53,150 So here's a gear ratio that would perform the 1760 01:24:53,150 --> 01:24:54,400 multiplication. 1761 01:24:54,400 --> 01:24:57,070 You can see that this stuff is beautifully machined, very 1762 01:24:57,070 --> 01:24:59,092 interesting and carefully done. 1763 01:24:59,092 --> 01:24:59,494 Yeah? 1764 01:24:59,494 --> 01:25:00,620 AUDIENCE: And they were doing this in the electrical 1765 01:25:00,620 --> 01:25:00,940 department. 1766 01:25:00,940 --> 01:25:02,200 PROFESSOR: This is in electrical engineering 1767 01:25:02,200 --> 01:25:03,050 department, right. 1768 01:25:03,050 --> 01:25:04,421 AUDIENCE: It seems very much like a mechanical project. 1769 01:25:04,421 --> 01:25:05,655 PROFESSOR: It does seem like a mechanical project. 1770 01:25:05,655 --> 01:25:07,330 That's a very good point. 1771 01:25:07,330 --> 01:25:11,820 And Bush actually said, he was very clear, he said, I want my 1772 01:25:11,820 --> 01:25:15,680 engineers to be able to design mathematical equations the way 1773 01:25:15,680 --> 01:25:17,110 they design circuits. 1774 01:25:17,110 --> 01:25:20,310 And he tried to make a circuit design-type 1775 01:25:20,310 --> 01:25:22,210 language, visual language-- 1776 01:25:22,210 --> 01:25:23,220 I redrew this picture. 1777 01:25:23,220 --> 01:25:24,710 But I redrew it from one of their papers. 1778 01:25:24,710 --> 01:25:28,180 It's the same terminology-- 1779 01:25:28,180 --> 01:25:31,410 that you could actually design these equations and make these 1780 01:25:31,410 --> 01:25:32,570 big kind of systems. 1781 01:25:32,570 --> 01:25:35,360 And already you're beginning to see a move toward 1782 01:25:35,360 --> 01:25:36,530 generality. 1783 01:25:36,530 --> 01:25:40,670 So he says, this is not a device to evaluate integrals 1784 01:25:40,670 --> 01:25:43,450 for studying transience in the electric power industry. 1785 01:25:43,450 --> 01:25:45,650 This is a research device for a general 1786 01:25:45,650 --> 01:25:47,480 purpose calculating machine. 1787 01:25:47,480 --> 01:25:49,570 And it's interesting, he goes to the Rockefeller-- 1788 01:25:49,570 --> 01:25:52,860 well, I'll cover that in a minute. 1789 01:25:52,860 --> 01:25:55,370 So already you're beginning to see this guy beginning to 1790 01:25:55,370 --> 01:25:58,960 think in a more general, kind of fundamental terms, as 1791 01:25:58,960 --> 01:26:01,180 opposed to in these specific terms. 1792 01:26:01,180 --> 01:26:03,870 And this is within just a couple of years of Compton 1793 01:26:03,870 --> 01:26:06,550 coming here to MIT. 1794 01:26:06,550 --> 01:26:09,160 Here's the output of the device. 1795 01:26:09,160 --> 01:26:12,280 You can see it's basically creating a family of curves. 1796 01:26:12,280 --> 01:26:15,350 And they were very into the fact that they 1797 01:26:15,350 --> 01:26:16,570 didn't need any algebra. 1798 01:26:16,570 --> 01:26:18,320 They didn't need any equations. 1799 01:26:18,320 --> 01:26:20,250 They said the world is basically analog. 1800 01:26:20,250 --> 01:26:21,190 They didn't use that term. 1801 01:26:21,190 --> 01:26:23,170 And said, the world is continuous. 1802 01:26:23,170 --> 01:26:25,850 Our integrator is continuous and 1803 01:26:25,850 --> 01:26:28,530 produces continuous outputs. 1804 01:26:28,530 --> 01:26:32,330 And again, you can see this kind of 1805 01:26:32,330 --> 01:26:33,660 graphical user interface. 1806 01:26:33,660 --> 01:26:35,850 There's a little magnifying glass there. 1807 01:26:35,850 --> 01:26:38,700 And he's kind of following these curves, which was a kind 1808 01:26:38,700 --> 01:26:40,800 of manual input. 1809 01:26:40,800 --> 01:26:43,410 Bush is kind of looking over the shoulder there. 1810 01:26:43,410 --> 01:26:44,920 And they would evaluate all these 1811 01:26:44,920 --> 01:26:46,170 different kinds of curves. 1812 01:26:50,950 --> 01:26:53,260 Here's another view, where they're all connected by an 1813 01:26:53,260 --> 01:26:54,930 electrical audio system. 1814 01:26:54,930 --> 01:26:57,080 And there's one guy in the center, telling everybody OK, 1815 01:26:57,080 --> 01:26:58,610 follow your curves now. 1816 01:26:58,610 --> 01:27:01,100 And here, he's not doing it by hand so much anymore. 1817 01:27:01,100 --> 01:27:03,790 He's turning a little crank to trace all the curves. 1818 01:27:03,790 --> 01:27:07,370 And you can begin to see by the curves, they can do some 1819 01:27:07,370 --> 01:27:08,470 pretty complicated things. 1820 01:27:08,470 --> 01:27:11,620 And there's a whole kind of science of analog computing 1821 01:27:11,620 --> 01:27:15,420 that comes up in the '30s around these machines, where 1822 01:27:15,420 --> 01:27:17,730 they measure the number of integrators the way you would 1823 01:27:17,730 --> 01:27:21,120 measure the number of megahertz of processor that 1824 01:27:21,120 --> 01:27:22,900 you have in your computer. 1825 01:27:22,900 --> 01:27:25,920 Because the integrator was the expensive thing that kind of 1826 01:27:25,920 --> 01:27:29,060 described what order equation you could possibly model with 1827 01:27:29,060 --> 01:27:30,000 these things. 1828 01:27:30,000 --> 01:27:34,330 And people start to use them to model electron orbits in 1829 01:27:34,330 --> 01:27:35,420 atomic physics. 1830 01:27:35,420 --> 01:27:38,190 They used them particularly for ballistics. 1831 01:27:38,190 --> 01:27:39,690 The Army gets really interested. 1832 01:27:39,690 --> 01:27:42,630 And they have to calculate ballistic equations for all 1833 01:27:42,630 --> 01:27:44,470 different kinds of guns and shells. 1834 01:27:44,470 --> 01:27:47,120 And this makes it a lot more convenient. 1835 01:27:47,120 --> 01:27:52,830 And so you begin to see the move away from, even with the 1836 01:27:52,830 --> 01:27:56,080 same research group, the same people literally, from this 1837 01:27:56,080 --> 01:27:58,840 kind of specific industry oriented work toward more 1838 01:27:58,840 --> 01:28:01,230 general work in what they think of as a 1839 01:28:01,230 --> 01:28:04,140 general purpose computing. 1840 01:28:04,140 --> 01:28:07,760 This is kind of the most famous picture of the device. 1841 01:28:07,760 --> 01:28:10,200 And you can see there three integrators 1842 01:28:10,200 --> 01:28:11,450 inside their glass cases. 1843 01:28:11,450 --> 01:28:15,200 Those integrated became so precise that you had to have 1844 01:28:15,200 --> 01:28:17,720 them covered, free of dust, and 1845 01:28:17,720 --> 01:28:20,300 really very well protected. 1846 01:28:20,300 --> 01:28:22,580 And it turns out there was a integrator that was developed 1847 01:28:22,580 --> 01:28:25,190 secretly by the Navy for controlling the big guns on 1848 01:28:25,190 --> 01:28:27,500 battleships, that was better than this one, that they 1849 01:28:27,500 --> 01:28:30,550 weren't really aware yet. 1850 01:28:30,550 --> 01:28:34,590 And has nobody ever see a tubal integrator? 1851 01:28:34,590 --> 01:28:36,915 It's a whole other kind of mechanism that you can use to 1852 01:28:36,915 --> 01:28:38,910 do mechanical integration. 1853 01:28:38,910 --> 01:28:42,250 So then this project spurs a whole bunch of different other 1854 01:28:42,250 --> 01:28:44,830 kinds of projects. 1855 01:28:44,830 --> 01:28:50,820 One is called the cinema intergraph, where the idea is 1856 01:28:50,820 --> 01:28:53,460 instead of integrating with these kind of problematic 1857 01:28:53,460 --> 01:28:56,690 mechanical integrators, you integrate using this exotic 1858 01:28:56,690 --> 01:28:57,710 new technology. 1859 01:28:57,710 --> 01:29:00,330 Anybody want to guess what that is over on the left? 1860 01:29:00,330 --> 01:29:02,440 It's a photo cell. 1861 01:29:02,440 --> 01:29:07,720 And they would actually plot the mathematical curves as 1862 01:29:07,720 --> 01:29:10,780 images on this 35 millimeter film. 1863 01:29:10,780 --> 01:29:13,600 And then shine a light through it and plot the area under the 1864 01:29:13,600 --> 01:29:18,460 curves by integrating the charge that came through the 1865 01:29:18,460 --> 01:29:20,030 photo cell. 1866 01:29:20,030 --> 01:29:23,730 And this is the guy who made it. 1867 01:29:23,730 --> 01:29:26,730 As he said, it was mostly a machine for producing 1868 01:29:26,730 --> 01:29:27,155 dissertations. 1869 01:29:27,155 --> 01:29:30,100 It had essentially no practical output. 1870 01:29:30,100 --> 01:29:33,310 But it was important in that, this guy is named Gordon 1871 01:29:33,310 --> 01:29:37,550 Brown, who is a student of Harold Hazen, and becomes the 1872 01:29:37,550 --> 01:29:40,330 dean of engineering right at the end of the 1873 01:29:40,330 --> 01:29:41,480 Second World War. 1874 01:29:41,480 --> 01:29:44,090 And is the guy who closes down all that old-fashioned 1875 01:29:44,090 --> 01:29:45,030 electrical machinery. 1876 01:29:45,030 --> 01:29:46,640 We read about him a little bit. 1877 01:29:46,640 --> 01:29:47,870 I think it was in the [? Laquier ?] 1878 01:29:47,870 --> 01:29:49,420 article. 1879 01:29:49,420 --> 01:29:53,090 And kind of is the dean of engineering when they kind of 1880 01:29:53,090 --> 01:29:55,580 formalized a lot of things after the Second World War. 1881 01:29:58,600 --> 01:30:00,490 And there's another picture of the cinema intergraph. 1882 01:30:00,490 --> 01:30:03,450 Also one of his advisers on there was Norbert Wiener, who 1883 01:30:03,450 --> 01:30:05,630 was also very closely related to Bush's work. 1884 01:30:05,630 --> 01:30:08,930 And a lot of his earlier ideas of cybernetics also came out 1885 01:30:08,930 --> 01:30:11,220 of this work. 1886 01:30:11,220 --> 01:30:13,460 This is Harold Hazen again. 1887 01:30:13,460 --> 01:30:15,840 It's called an automatic curve follower. 1888 01:30:15,840 --> 01:30:19,260 And his idea is, gee, maybe I could make these photo cells 1889 01:30:19,260 --> 01:30:22,230 just follow these curves automatically. 1890 01:30:22,230 --> 01:30:26,030 And today, you can go to the Science Museum and buy a 1891 01:30:26,030 --> 01:30:28,180 little robot kit with a robot that follows a 1892 01:30:28,180 --> 01:30:29,370 line across the floor. 1893 01:30:29,370 --> 01:30:31,720 This is the first one of those. 1894 01:30:31,720 --> 01:30:34,300 But what's much more interesting and important than 1895 01:30:34,300 --> 01:30:38,440 that about this, was that in order to do this and order to 1896 01:30:38,440 --> 01:30:41,120 make the differential analyzer work, it's the amount of 1897 01:30:41,120 --> 01:30:43,090 friction that builds up in the mechanisms. 1898 01:30:43,090 --> 01:30:46,260 And it gets to a point where you basically just can't turn 1899 01:30:46,260 --> 01:30:47,040 the crank anymore. 1900 01:30:47,040 --> 01:30:49,190 And you start to lose a lot of accuracy. 1901 01:30:49,190 --> 01:30:50,870 You don't lose it in the gears. 1902 01:30:50,870 --> 01:30:52,500 Eventually you would, because they would break. 1903 01:30:52,500 --> 01:30:55,090 But you lose it in all these other systems, particularly 1904 01:30:55,090 --> 01:30:55,930 the integrator. 1905 01:30:55,930 --> 01:30:59,770 So what they do is they put what they call followers or 1906 01:30:59,770 --> 01:31:03,510 servomechanisms between the stages, where they can kind of 1907 01:31:03,510 --> 01:31:08,300 renew the signal and add energy to the system. 1908 01:31:08,300 --> 01:31:11,250 Because with a mechanical system, if you don't have any 1909 01:31:11,250 --> 01:31:13,590 energy, it's just going to eventually-- 1910 01:31:13,590 --> 01:31:14,870 the energy is all dissipated. 1911 01:31:14,870 --> 01:31:18,510 But if you can carry the data from one point to another and 1912 01:31:18,510 --> 01:31:21,050 just add energy and make it constantly stronger, you can 1913 01:31:21,050 --> 01:31:22,700 build them as big as you want. 1914 01:31:22,700 --> 01:31:25,830 And it's between that problem and this problem that Hazen 1915 01:31:25,830 --> 01:31:28,760 actually writes the first paper ever on what he calls 1916 01:31:28,760 --> 01:31:31,900 the theory of servomechanisms, which you now what know as 1917 01:31:31,900 --> 01:31:33,040 feedback control theory. 1918 01:31:33,040 --> 01:31:36,310 And anybody take a course on that, or probably in every 1919 01:31:36,310 --> 01:31:38,890 engineering course you're taking something in feedback 1920 01:31:38,890 --> 01:31:40,260 control theory. 1921 01:31:40,260 --> 01:31:42,690 And he became interested in these basic problems. 1922 01:31:42,690 --> 01:31:46,210 Until that point, people had governors on steam engines. 1923 01:31:46,210 --> 01:31:48,520 They had different kinds of regulators in this electric 1924 01:31:48,520 --> 01:31:50,120 power network they were working on. 1925 01:31:50,120 --> 01:31:53,030 But nobody had thought of, let's write about the theory 1926 01:31:53,030 --> 01:31:56,110 of how this feedback mechanism works overall. 1927 01:31:56,110 --> 01:31:58,070 And there again, there's another one of these, a little 1928 01:31:58,070 --> 01:32:00,640 more detailed example of an intellectual way that 1929 01:32:00,640 --> 01:32:03,410 Compton's move was not just administrative, he didn't just 1930 01:32:03,410 --> 01:32:05,090 say let's stop working with industry 1931 01:32:05,090 --> 01:32:06,210 and think about science. 1932 01:32:06,210 --> 01:32:08,600 He actually influenced these people in their labs very 1933 01:32:08,600 --> 01:32:11,430 quickly, within a couple years, to start thinking about 1934 01:32:11,430 --> 01:32:13,930 fundamental problems as opposed to just these kind of 1935 01:32:13,930 --> 01:32:14,990 immediate problems. 1936 01:32:14,990 --> 01:32:17,623 Hazen also becomes dean of engineering at MIT during the 1937 01:32:17,623 --> 01:32:20,401 Second World War and head of the electrical engineering 1938 01:32:20,401 --> 01:32:21,790 department. 1939 01:32:21,790 --> 01:32:25,630 Here's his model of servomechanisms. 1940 01:32:25,630 --> 01:32:29,210 Also in that group, looking at again this electric power 1941 01:32:29,210 --> 01:32:33,230 problem, and saw something literally in the electrical 1942 01:32:33,230 --> 01:32:36,700 power problem that was bigger than simply 1943 01:32:36,700 --> 01:32:37,600 the immediate problem. 1944 01:32:37,600 --> 01:32:39,070 Anybody want to get who this is? 1945 01:32:42,060 --> 01:32:43,345 Let me describe what he's doing and 1946 01:32:43,345 --> 01:32:44,190 maybe then you'll guess? 1947 01:32:44,190 --> 01:32:46,670 So you can actually see in this picture, he says, I'm 1948 01:32:46,670 --> 01:32:47,870 going to look at these generators. 1949 01:32:47,870 --> 01:32:49,470 And the problem is when they have these 1950 01:32:49,470 --> 01:32:50,680 transients of these-- 1951 01:32:50,680 --> 01:32:54,980 they fall out of step, so that in an A/C system, everything 1952 01:32:54,980 --> 01:32:56,720 has to be running in perfect synchrony. 1953 01:32:56,720 --> 01:32:58,840 And if it's not running synchronized, you get all 1954 01:32:58,840 --> 01:32:59,630 kinds of issues. 1955 01:32:59,630 --> 01:33:06,430 And he says, I'm going to tape cardboard N and S. So that I'm 1956 01:33:06,430 --> 01:33:09,570 going to tape them to each of the poles on the generator and 1957 01:33:09,570 --> 01:33:11,950 then let the generator spin really fast. 1958 01:33:11,950 --> 01:33:14,220 And then I'm going to shine a light on it and I'm going to 1959 01:33:14,220 --> 01:33:17,840 pulse the light at exactly the same frequency as the 1960 01:33:17,840 --> 01:33:19,830 generator is supposed to be spinning. 1961 01:33:19,830 --> 01:33:22,060 And that will freeze the N and S in your eye 1962 01:33:22,060 --> 01:33:23,240 when you look at it. 1963 01:33:23,240 --> 01:33:25,720 And then if there's a phasing problem, you'll see the N and 1964 01:33:25,720 --> 01:33:27,810 the S moving back and forth. 1965 01:33:27,810 --> 01:33:29,195 Now, anybody want to guess who this is? 1966 01:33:29,195 --> 01:33:29,510 AUDIENCE: Edgerton. 1967 01:33:29,510 --> 01:33:30,580 PROFESSOR: This is Edgerton, right? 1968 01:33:30,580 --> 01:33:34,320 And this is the first application he have of this 1969 01:33:34,320 --> 01:33:35,230 stroboscope. 1970 01:33:35,230 --> 01:33:37,340 And very soon, he says hey, you know what, this 1971 01:33:37,340 --> 01:33:38,900 stroboscope thing is really interesting. 1972 01:33:38,900 --> 01:33:40,950 I can make some innovations there. 1973 01:33:40,950 --> 01:33:42,610 Forget about electric power stuff. 1974 01:33:42,610 --> 01:33:46,620 I'm interested in high-speed photography and generally 1975 01:33:46,620 --> 01:33:49,300 high-speed electrical discharge. 1976 01:33:49,300 --> 01:33:51,020 AUDIENCE: It's like the first timing light for a car. 1977 01:33:51,020 --> 01:33:51,390 PROFESSOR: Yeah. 1978 01:33:51,390 --> 01:33:53,790 It's exactly the same as the timing light for a car. 1979 01:33:53,790 --> 01:33:55,560 Most of which are made by EG&G, which 1980 01:33:55,560 --> 01:33:56,980 was Edgerton's company. 1981 01:33:56,980 --> 01:34:01,410 And so there again, he gets interested in a bunch of 1982 01:34:01,410 --> 01:34:02,140 different things. 1983 01:34:02,140 --> 01:34:06,700 But all of them have in common this idea of like how even 1984 01:34:06,700 --> 01:34:07,730 most of the flashes-- 1985 01:34:07,730 --> 01:34:10,190 you don't see it so much in your digital camera, with the 1986 01:34:10,190 --> 01:34:11,060 little teeny ones. 1987 01:34:11,060 --> 01:34:16,510 But if you ever have a big flash, it fires and then you 1988 01:34:16,510 --> 01:34:18,020 hear it charging up. 1989 01:34:18,020 --> 01:34:19,000 And then it fires all again. 1990 01:34:19,000 --> 01:34:26,340 And Edgerton really became an expert at very rapid discharge 1991 01:34:26,340 --> 01:34:28,080 of electrical energy. 1992 01:34:28,080 --> 01:34:30,180 I work a lot at the Undersea World, where Edgerton did a 1993 01:34:30,180 --> 01:34:31,480 lot of work with sonar. 1994 01:34:31,480 --> 01:34:34,570 But the particular kind of sonar he built was very much 1995 01:34:34,570 --> 01:34:37,350 like the flash bulb, in that it was a sonar 1996 01:34:37,350 --> 01:34:39,070 that flashed the sound. 1997 01:34:39,070 --> 01:34:42,690 It's called side-scan sonar, rather than continuous wave 1998 01:34:42,690 --> 01:34:45,300 sonar, would just gave it all the time. 1999 01:34:45,300 --> 01:34:49,950 So for the plutonium bomb in particular, the one during 2000 01:34:49,950 --> 01:34:52,710 World War II, and I think they still are spherical, and you 2001 01:34:52,710 --> 01:34:54,730 had to implode this device. 2002 01:34:54,730 --> 01:34:57,470 And a guy at Harvard, Kistiakowsky, made these 2003 01:34:57,470 --> 01:34:59,190 explosive lenses. 2004 01:34:59,190 --> 01:35:01,970 And you had to trigger them all around this sphere at 2005 01:35:01,970 --> 01:35:03,830 exactly the same moment. 2006 01:35:03,830 --> 01:35:06,530 Otherwise, you were going to get a lopsided shock wave and 2007 01:35:06,530 --> 01:35:08,590 you weren't going to implode the thing perfectly. 2008 01:35:08,590 --> 01:35:11,230 And it was Edgerton's company that designed the triggering 2009 01:35:11,230 --> 01:35:13,280 mechanisms for that atomic bomb. 2010 01:35:13,280 --> 01:35:16,080 They also did high-speed photography of the actual 2011 01:35:16,080 --> 01:35:16,830 mushroom clouds. 2012 01:35:16,830 --> 01:35:19,230 And it's amazing, sort of frightening imagery that 2013 01:35:19,230 --> 01:35:22,970 they've collected all through the Cold War about that. 2014 01:35:22,970 --> 01:35:25,090 And that was EG&G.
