Bernard Waldman (1913-1986) was an American physicist who became the Associate Director of the National Superconducting Cyclotron Laboratory at Michigan State University (NSCL.)
Waldman worked on the Manhattan Project in multiple capacities. Arriving at Los Alamos in 1943 after a five year stretch on the physics faculty at the University of Notre Dame, he became an instrumental part of the development of the atomic bomb. He served at the Los Alamos main project site and was present for the 1945 Trinity test before being appointed to Project Alberta.
In August 1945 he flew on the observational aircraft Necessary Evil during the Hiroshima bombing mission as a camera operator and chief observer. However he forgot to open the camera's shutter before the mission began, and he was unable to record any footage of the bombing.
After the war, Waldman became an advocate of civilian control of atomic weapons. He declared in 1946 that "We are actively in an armaments race right now and will be as long as the military has control [of atomic weapons.]" He would remain active in the physics community, teaching at Notre Dame for several years before leading the NSCL at the end of his career.
