Louis Hempelmann: He [J. Robert Oppenheimer] just told me what the situation was. He did not ask me, which is the same thing when he got sick because I was in the radiology department here and I knew something about it. He would call me up, tell me what he had done, and then say “What do you think of it?” By that time, the only thing I could say was, “That was fine.”
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—
Nate Weisenberg: My name is Nate Weisenberg. I am doing this interview for the Atomic Heritage Foundation with Kathleen Maxwell here in Wellesley, Massachusetts. It is Monday, April 25, 2016.
How did you get involved with the Manhattan Project?
Kathleen Maxwell: I had just finished my Master’s degree at Smith [College], and I was contemplating staying at Smith because the main men in our department there had gone to work for the Manhattan Project someplace else.
Jersey City was home to the headquarters of the M. W. Kellogg Company, which specialized in chemical engineering projects. In 1942, the S-1 Committee tasked Kellogg with conducting research into the feasibility of the gaseous diffusion process for separating uranium isotopes. As the Manhattan Project began, Kellogg's vice president of engineering, Percival "Dobie" Keith, took charge of a newly created subsidiary of Kellogg, the Kellex Corporation.
Martin Sherwin: This is an interview with Professor Joseph Rotblat, R-O-T-B-L-A-T, at his office in London. Well it really was quite a production. Seven hours!
Joseph Rotblat: Yes, oh yes, quite a production.
Sherwin: I thought Sam Waterston played a marvelous part.
Sherwin: The person who played [J. Robert] Oppenheimer.
Martin Sherwin: The work must have been sort of very frustrating for a while, before that [Stanislaus] Ulam-[Edward] Teller breakthrough [on the hydrogen bomb].
Ed Hammel: Well, sure. There was—
Sherwin: What were you doing at that time?
Hammel: At that point, I continued with having this group in charge of properties of plutonium. But one of the things that we were very interested in was the low temperature properties, the specific heat specifically, of plutonium.
Several sites in Iowa played an important role during and after the Manhattan Project, including the Ames Laboratory at the Iowa State University where uranium production methods were developed, and the Burlington Atomic Energy Commission Plant, where atomic weapons were first assembled by the AEC.
