Stanislaus Ulam's Interview (1979)

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—

Ulam:  Yes.

Kathleen Maxwell's Interview

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.

Lee DuBridge's Interview - Part 2

Lee DuBridge: So, yeah, we thought it was an exciting time to have the AEC [Atomic Energy Commission]. We knew, of course, that they were going ahead with the weapon development, but also they were going to support Brookhaven and other research centers around the country. So, no, I think those of us who were not imminently in the Manhattan District, but aware of it, were quite excited about getting in and finding out more about really what was going on and what the new possibilities were, both in physics and in weapon technology.

Norris Bradbury's Interview - Part 2

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.

Louis Hempelmann's Interview - Part 2

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.”

Jersey City, NJ

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.

Joseph Rotblat's Interview

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.

Rotblat: Who?

Sherwin: The person who played [J. Robert] Oppenheimer.
