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. 

Ralph Gates's Interview

Wendy Steinle: Good morning, Ralph. I’m Wendy Steinle, as you know, and I am really pleased to be your friend and to have the opportunity to interview you this morning. Just for the record, will you start by stating and spelling your name, and then tell us the date?

Murray Peshkin's Interview

Murray Peshkin:  Well, how did I get involved in the Manhattan Project? I was an undergraduate student at Cornell University. A group of about ten, who were studying physics. It was clear that we could not be kept out of the Army very long. They were looking for programs in which we could serve usefully. I really believed that there was something else behind it.

Murray Peshkin

Murray Peshkin is a Manhattan Project veteran and a physicist. He was recruited by the Army to assist the Manhattan Project at Los Alamos when he was an undergraduate student studying physics at Cornell.
