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.

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.

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.
