Robert Lamphere's Interview - Part 1

Robert Lamphere: One of the British newspapers speculated about allowing the FBI into see this guy [Klaus Fuchs], because we might actually use the third degree against him – which we thought was funny as hell. But right off the bat, he wasn’t sure he wanted to tell me anything, because of what we filed against ‒ particularly his sister, Kristel Heineman, and her husband, and others. So he and I fenced a little bit back and forth before we ever showed him the pictures or anything else. As to whether he was going to talk at all‒

Charles Critchfield's Interview

Charles Critchfield: Is that your book, by the way?

Richard Rhodes: Yes.

CritchfieldMaking of the Atomic Bomb?

Rhodes: Yes.

Critchfield: I’ve always heard it, Making of the Bomb. No, I didn’t know it was your book. Rubby Sherr sent me that, and he also sent me excerpts from two or three other books on the bomb. Rubby was my main man in my group for making the Initiator.

J. Carson Mark's Interview

Carson Mark: We shouldn’t have been making this damn bomb without trying to keep it secret from [Joseph] Stalin. We should’ve been talking to him like [Niels] Bohr said. [Klaus] Fuchs believed and took it into his own hands to make sure that the conversation went on. Of course, he didn’t need to because Stalin knew anyway. Not the technical details, but the general facts.

Louis Rosen's Interview

Rosen: Well, my name is Louis Rosen. I was born in New York City, not the best part of the city. I’m now almost eighty-five years old. My parents were immigrants from Poland.  They were escaping from the pogroms, which were taking place with the Russian Cossacks coming in and raiding villages, especially where Jews where plentiful. My father came over here in about 1909. My mother—they were girl and boyfriends in the old country—came over two years later.

Robert Serber's Interview (1994)

Robert Serber: Ernest [Lawrence] got overexcited about the Russian bomb. I imagine that [Edward] Teller called him and got him worked up. I warned him about Edward’s Super, that it wasn't a practical idea at the moment. I told him if he wanted to really find out he should talk to [Hans] Bethe, but he never did. He was all gung ho for the Super and he immediately went with more or less the action before he thought of what he could do, and the thing to do was to build these reactors to make tritium.

Stanislaus Ulam's Interview (1983)

Richard Rhodes: An interview with Dr. Stanislaw Ulam in Santa Fe, New Mexico, July 6, 1983.

Rhodes: Well I have some questions for you.

Ulam: Yes, of course. How long are you staying?

Rhodes: I am going to be in the area for until Saturday morning. It would be pleasant to see more of you. I thought I would go out to Los Alamos today and stay up there.

Ulam: There is a hotel.

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.
