Raemer Schreiber's Interview (1993)

Raemer Schreiber: Yes, there was at least one [bomb core], and people back here worked furiously taking the plutonium as it arrived and converting it into another core. I don’t know the answer to it. I have heard stories another core was on its way out at the time of the surrender.

Richard Rhodes: Groves decided not to ship it. I’ve seen the document.

Emilio Segrè's Interview

Richard Rhodes: This will be a tape of an interview with Doctor Segrè. That's E-m-i-l-i-o, S-e-g-r-e at his home in Lafayette, California on the 29th of June 1983. 

I have been, for example, through the Oppenheimer Papers, I’ve been through the [Leo] Szilard Papers in La Jolla. All of the books, most of the books have errors of one kind or the other.

Segrè: The Oppenheimer Papers, I have never gone through, but you have seen the letters of Oppenheimer?

George Cowan's Interview (1993)

George Cowan: What you’ve learned from the Russians, for example?

Richard Rhodes: The main thing I have learned is that their first bomb was a carbon copy of Fat Man.

Cowan Cowan: Well of course. I knew that in 1949, about the middle of September of ’49 because we analyzed the debris from that and it was clear that it was a carbon copy.

Hans Bethe's Interview (1993)

Richard Rhodes: Did David Holloway show you the documents that the Russians published?

Hans Bethe: Not the documents, but I got recent documents like [Yulii] Khariton.

Rhodes: Ah. They also published what [Klaus] Fuchs gave them. And, I have some of it here. I wanted to show you. You may not be able to comment. I think it is probably classified material in the United States.

Bethe: I do not know.

Harold Agnew's Interview (1994)

Rhodes: I am working on a book that would try to cover the years ’45 to ’55. I just finished the first 400 pages; it is all the Soviet bomb story, because so much has come available, including the espionage part of it. But, now I would like to get going and just simply try to deal with the development of the hydrogen bomb. And, most of all, I would like to describe the Mike shot, when you guys all came to put that together. But you also worked later, right, on Romeo? What was Romeo?

Nicholas Metropolis' Interview

Richard Rhodes: There are two particular themes that I am interested in that I know you were involved with very much. Anything else that you remember that you would want to talk about would be wonderful. One is the developing of computing. Los Alamos made a major contribution to the development of computing in the world. The other has to do with the period around the invention of the two-stage thermonuclear weapon. Could you talk about your experience with those things?

William Lanouette's Interview

Cindy Kelly: I’m Cindy Kelly from the Atomic Heritage Foundation. It is Friday, April 11, 2014, and I have with me William Lanouette who is going to be talking about Leo Szilard. Why don’t you start by actually saying your full name and spelling it? 

Bill Lanouette: I’m William Lanouette, L-A-N-O-U-E-T-T-E. 

Kelly: Tell us about Szilard. Who was he? What’s his background? 

Priscilla McMillan's Interview

Cindy Kelly: I am Cindy Kelly, Atomic Heritage Foundation, and today’s date is June 6, 2013. And we’re in Cambridge, Massachusetts with Priscilla McMillan. And I have a very easy question to begin with, which is, could you say your name, and spell it?

Priscilla McMillan: My name is Priscilla, P-R-I-S-C-I-L-L-A McMillan, M-C-M-I-L-L-A-N.

Jay Wechsler's Interview

Jay Wechsler: Well, my mother was visiting her folks in New York when she decided that it was time, and I was the first child, and I guess she was a little surprised. So I was born in New York even though we didn’t live there. And as soon as we were able we were back in New Jersey, where she and my father lived. My father was a chemist and even at a young age he was always taking me into the plant where he worked, showing me things. And I kind of had a mechanical bend or bent.
