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.

Ed Hammel's Interview

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.

Louis Hempelmann Interview - Part 1

Martin Sherwin: Martin Sherwin, I am about to interview Dr. Hempelmann at Strong Memorial Hospital.

You know, simply from all of the Los Alamos records, but who told me you were at Strong? That was, I think, Dorothy McKibbin.

Louis Hempelmann:  Oh yeah.

Sherwin: No, she confirmed it. She said you were coming out to Santa Fe.

Hempelmann: Yeah.

Ted Taylor's Interview - Part 4

Rhodes: Well, I had started to ask you about the Korean War. Was that a shock? Did that worry everyone and accelerate your sense of pressure?

Taylor: I don’t think so. I don’t remember any feeling of pressure, that we had to do something by a certain time or else all hell would break lose. All I remember was excitement and anticipation and eagerness to know the result of something I had worked on.

Ted Taylor's Interview - Part 3

Richard Rhodes: Although again, I was struck in Russia with how different a world that was.

Ted Taylor: Oh, yeah.

Rhodes: How much more closely they were—

Taylor: That is why I am so thankful because in many other places people get shot.

Rhodes: Yeah. We could not even get directions on the street. Nobody wanted to talk to foreigners. Even now, partly, I am sure.

Taylor: Some of that is habit, I think.

Alice Kimball Smith's Interview

Martin Sherwin: I am in Cambridge, Massachusetts on April 26, 1982. Were you married when you were in Los Alamos?

Alice Kimball Smith: Yes. We had been married for twelve years.

Sherwin: I see. So you and your husband, Cyril Smith, went to Los Alamos and you were promptly put to work as a schoolteacher. Is that correct?

Kimball Smith: That is right, yes.

Hans Bethe's Interview (1982) - Part 2

Hans Bethe: The other was M - A - D, MAD [Mutually Assured Destruction], which essentially says that nuclear weapons make sense only as a safeguard against nuclear weapons. As [Wolfgang] Panofsky has said recently, and there is actually an article by him, "It is not a doctrine. It is a fact of life. Nothing else is possible, whatever you might wish.” So I think you should not present it as something really unavoidable, without any movements in the opposite direction.  

Robert Lamphere's Interview - Part 2

Robert Lamphere: They said that he [Klaus Fuchs] annoyed some of the people because he wanted to keep certain [inaudible]. That’s a little point of irony. 

Richard Rhodes: Although, again, there was one guy who later thought, “Well, maybe he was pushing to find out what was the most valuable information.” Which I hadn’t thought of until I saw that comment.

Lamphere: I did not remember that at all. Don’t remember covering it in my interview.
