Siegfried Hecker's Interview - Part 1

Richard Rhodes: So what I thought we might do since you just came back from – was this work related to the Russian collaboration?

Siegfried Hecker: Yes.

Rhodes: Then maybe we should debrief you about that first before we go back and do the earlier part of the story. Does that make sense to you?

Hecker: Well, I do not know how you do these things. I am completely in your hands. Whatever you think makes sense.

Robert Lamphere's Interview - Part 3

Richard Rhodes: I really am going to have to go through and revise the Perseus discussion, I think.

Robert Lamphere: It’s got Lona [Cohen] and the tissue thing. I think it became a story that she told. But who’s to know?

I just found that Greenglass’s information on implosion was the first news the Soviets had of it. I just found that fascinating because I learned something.

Rhodes: It’s probably the reason they were willing to cross the two nets.

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.

Ted Taylor's Interview - Part 2

Richard Rhodes: You said [Richard] Courant’s work added realism?

Ted Taylor: Yeah.

Rhodes: How so?

Taylor: By going over various tricks for dealing with the discontinuities, the singularities in the hydrodynamics. I had the impression that he was very helpful to people like Bob Richtmyer. I don’t know that Richard himself came up with anything all new and different, I don’t know. But he was very articulate and active.

Marshall Rosenbluth's Interview

Richard Rhodes: How did you get involved in the program?

Marshall Rosenbluth: Well, you can probably guess. I’ve already told you that I was a student of [Edward] Teller’s. I was in the Navy during the war and then went back to the University of Chicago where my parents were living, to graduate school, and became a student of Teller’s. I’m not quite sure exactly how. He was a professor in one of my courses.

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.
