The Purdue University Physics Department operated a cyclotron during the early part of the war, conducting important nuclear research. Many of the scientists working on the project were transferred to Los Alamos to continue work on the Manhattan Project. For more information, see A History of Physics at Purdue: The War Period (1941-1945).

Martin Sherwin: This is Martin Sherwin. I’ll be interviewing Sir Rudolf Peierls at the State University of New York at Stony Brook. Today’s date is June 6th, 1979.  You first met [J.Robert] Oppenheimer in Zurich in 1929? Rudolf Peierls: Right, yes.
