Edwin McMillan: Ladies and gentlemen, I would like to start with two remarks. First, this is going to be a personal story, so if I use the first person singular, this is not pure egotism, it is simply the fact that that’s the part that I know best. Second remark is, the difficulty of establishing facts at such a late date, even of important things. During the Manhattan Project, of course, there was security impressed upon everyone, so very few people kept any notes.
Cynthia Kelly: I’m Cindy Kelly, Atomic Heritage Foundation, and it is Wednesday, August 24th, 2016. I am in Cleveland Heights, Ohio, and with me is Dr. Baldwin Sawyer. My first question for him is to say his name and spell it.
Baldwin Sawyer: Baldwin Sawyer, B-a-l-d-w-i-n S-a-w-y-e-r. My initials are B.S, and in case anybody is wondering, that stands for Boy Scout.
Kelly: Well, that’s interesting. [Laughs] Can you tell us when and where you were born?
Cindy Kelly: Okay, I am Cindy Kelly. This is Tuesday, August 9, 2016 in Berkeley, California. I have with me Dr. Geoffrey Chew. My first question to him is to say and spell his name.
Geoffrey Chew: Geoffrey Chew, G-E-O-F-F-R-E-Y C-H-E-W.
Kelly: Very good, so now we will move on to some harder stuff. If you could tell us when you were born and where, and a little bit about your own childhood.
Robert Bacher: I presented this [the discovery of the neutron] in the seminar and there were a good many questions. Some people were skeptical. I convinced Ed Condon almost immediately. In fact, within the week we had written a note together on the spin of the neutron because you could work it out. This part of it fit into the things of nuclear spins, hyperfine structure, nuclear moments, and so on. A good many other people came around to it. I think more than half the people were convinced at that time.
[Many thanks to Thomas Scanlan for recording and donating this interview to the Atomic Heritage Foundation.]
Thomas Scanlan: —Is part of an interview, which I held with Professor Marvin Wilkening at his home on Socorro, New Mexico on July 15, 1995.
Now, I was reading that you had worked at four different places associated with the Manhattan Project.
Marvin Wilkening: That’s right.
Scanlan: Was your first work with [Enrico] Fermi at Chicago?
Martin Sherwin: Okay, this is the middle of an interview with Norris Bradbury.
Norris Bradbury: The fact that I wasn’t particularly involved in these discussions, of the type which the Federation of Atomic Scientists started—they started here, of course. I suppose I was committed to running a laboratory and trying to get people to stay here, while I was not uncommitted to international control of nuclear weapons, for heaven’s sakes. No one could be.
Martin Sherwin: This is Martin Sherwin. Today is March 29, 1983. I am going to interview Professor Robert F. Bacher – B-a-c-h-e-r – in his office on the Caltech campus in Pasadena.
Martin Sherwin: I’m interviewing Robert Serber at his home in New York City. Date is January 9th, 1982.
Let me just begin at the beginning and ask you, how did you get to Berkeley? Why did you go there?
Serber: I got my degree at Wisconsin with [John] Van Vleck, and that was ’34. You didn’t have very many choices of what you can do. But I got a National Research Fellowship, which, if I recall, there were only five of them available that year. That was a year when the new membership of the American Physical Society was thirteen.
Martin Sherwin: This is Martin Sherwin, I’m on my way to interview William Fowler at Caltech in Pasadena. Today is March 29, 1983.
Stanislaus Ulam: You know, after forty-five years in this country, my accent is still very hard.
Martin Sherwin: That’s all right. I still have a Brooklyn accent.
Ulam: Oh, you do?
Sherwin: I left Brooklyn twenty years ago. I think even though I do know a lot of the answers to some of the questions I’m going to ask you from your book—
