The citation on his Los Alamos award called him “the driving force in the early radiochemical evaluations of nuclear weapons.”
Dr. Cowan began thinking about the possibility of a bomb in 1938, when he brought a clipping about nuclear fission to his physics professor and asked him to talk about the possibility of a weapon based on splitting the atom.
