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.

John Arnold's Interview

Stephane Groueff: Now if you can give me briefly your background and where you came from and how you got connected with Kellex. Were you a Kellogg man?

John Arnold: Yes, I was a Kellogg man, and at the time I was working on an ammonia plant at Sterlington.

Arnold: In Louisiana.

Groueff: Louisiana?

Robert E. Hayes's Interview

Hans Bethe's Interview

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?

Jimmy Vale

Stephane Groueff: This is Jimmy Vale, the cyclotron of Berkeley, about Dr. Lawrence.

Jimmy Vale: I told these stories to Mr. Herbert Childs, who is writing a biography of Lawrence.

Groueff: Oh, yeah. I have heard about it, but my book will just have a paragraph on Lawrence.
