This continues a tradition that began seventy years ago of scientists having a role in educating the public, advising government officials, and helping shape policy about nuclear weapons.
Soon after the end of World War II, scientists mobilized themselves to address the pressing issues of how to deal with the many consequences of atomic energy. Of prime importance was the question of which government entity would control the research, development and production of atomic weapons, and any peaceful applications. Would it be the military, as it was during World War II, or a civilian agency, such as the newly created Atomic Energy Commission (AEC)?
