Oppenheimer, Inventor Atomic Bomb > 
Upon hearing of discovery of fission in 1939, J. Robert Oppenheimer immediately grasped the possibility of atomic bombs. In 1941, he was brought into the atomic bomb project and was asked to calculate the critical mass of uranium-235, the amount needed to sustain a chain reaction. The next year he assembled a group of some of the best theoretical physicists in the country to discuss the design of the actual bomb. General Leslie Groves, the army officer in charge of the Manhattan Project, named Oppenheimer the scientific director of the program, and together they decided on Los Alamos, New Mexico, as the site for the nuclear weapons laboratory. Groves said of Oppenheimer, "He's a genius. A real genius...Why, Oppenheimer knows about everything. He can talk to you about anything you bring up. Well not exactly. I guess there are a few things he doesn't know about. He doesn't know anything about sports."
