The Manhattan Project -- Its Establishmentby Mary Schorn 03 Aug, 2012 in Science Communications
On August 13, 1942, the Manhattan Engineer District, whose name was based upon the geographical location of its headquarters, was established. In September, the Army appointed Colonel Leslie R. Groves to head the effort. Groves held that the exigencies of war required scientists to move from laboratory research to development and production in record time. Though traditional scientific caution might be short-circuited in the process, there was no alternative if a bomb was to be built in time to be used in the current conflict (World War II). Various isotope separation methods (uranium enrichment) to produce uranium-235 were being researched at this time. One was gaseous diffusion being done at Columbia and another was the electromagnetic method being done at Berkeley under Ernest O. Lawrence. Based upon the success of the electromagnetic method, the S-1 (The Office of Scientific Research and Development Section On Uranium) Executive Committee recommended building plants in Tennessee at Site X (now Oak Ridge). During this time, construction was taking place on the Stagg Field pile -- CP-1 (Chicago Pile Number one) at the Metallurgical Laboratory in Chicago where Enrico Fermi was conducting his research on chain reactions . Also occurring was Glenn Seaborg's inventive work with plutonium, particularly his investigations on plutonium's oxidation...
