Eyewitness account


By the late 1930s, physicists believed a “super bomb” using nuclear fission was theoretically possible. In 1941 President Franklin D. Roosevelt established the MANHATTAN Project to develop such a weapon. The first test of the atomic bomb took place in the desert outside Alamogordo, New Mexico, on July 16, 1945.
