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.

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.

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.
