Joseph Katz's Interview

Joseph Katz: Now it was recognized that plutonium would have a chemistry that would be quite similar to that of uranium. And developing procedures for the separation of plutonium from irradiated uranium. The assumption that was most commonly made was that the chemistry of plutonium would be similar, if not identical to that of uranium and this, of course was an entirely reasonable assumption to make.

Ray Gallagher and Fred Olivi's Interview - Part 1

Announcer: Here is your host and moderator, Milton Rosenberg.

Milton Rosenberg: Our guests tonight all know a great deal about the bombing of Hiroshima and Nagasaki, but from different vantage points, two of them from the vantage point of being up in the air and helping to drop the bombs. They are Fred Olivi, who was the co-pilot of Bockscar. That was the plane that actually delivered the bomb to Nagasaki.

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.

Louis Rosen

Louis Rosen, a native New Yorker and the son of Polish immigrants, was personally selected to work on the Manhattan project in Los Alamos while a graduate student in physics. Once in Los Alamos, Rosen was assigned to Edwin McMillan’s group, where he worked on implosion technology. Rosen remained in Los Alamos after the war ended and was considered the father of the Los Alamos Meson Physics Facility.
