ABSTRACT
In 1964 Oppenheimer returned to Los Alamos to give a public address on "Niels Bohr and the Atomic Bomb"-an explicit acknowledgment of the great physicist's magisterial place among the scientific authorities of this century. Niels Bohr was the first person not only to advocate nuclear arms control, but also to formulate its fundamental principles and work to have them adopted by Western governments. In ways not generally recognized, he set the intellectual agenda, both theoretically and politically, for the postwar nuclear arms control movement. At the heart of his proposal were a scientist's distrust of secrecy and the recognition that the existence of nuclear weapons demanded an environment in which each nation could be confident that no potential enemy was stockpiling these weapons. He therefore urged Roosevelt to consider "any arrangement which can offer safety against secret preparations".
