American scientists, many of them refugees from fascist regimes in Europe, took steps in 1939 to organize a project to exploit the newly recognized fission process for military purposes. The first contact with the government was made by G.B. Pegram of Columbia University, who arranged a conference between Enrico Fermi and the Navy Department in March 1939. In the summer of 1939, Albert Einstein was persuaded by his fellow scientists to use his influence and present the military potential of an uncontrolled fission chain reaction to President Franklin D. Roosevelt. On December 6, 1941, the project was put under the direction of the Office of Scientific Research and Development. In June 1942 the Corps of Engineers' Manhattan District was assigned management of the construction work. "Manhattan Project" became the code name for research work that would extend across the country) |
