The Manhattan Project


Lew Kowarski's Interview - Part 2

Stephane Groueff: One thing I don’t understand, and it’s a very ignorant question, but what was actually the difference between [Enrico] Fermi’s experiment in ’34 and [Otto] Hahn’s? Because, why do we say that Hahn was the first one, while Fermi also bombarded uranium?

Lew Kowarski: I don’t it’s true to say that Hahn was the first one.

Groueff: It’s not true.

Kowarski: I think it’s one of those simplifications—there are people who find them all right. I don’t.

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.

Steinle: What is today’s date?
