Groves was bold and willing to spend money. When scientists and engineers were unable to decide which of three approaches to producing the fissile material needed to build the bomb, he decided that if nobody could tell which was best, the thing to do was try all three methods. Huge manufacturing facilities were built at Oak Ridge, Tennessee and Hanford, Washington. Assuming that fissile material would be ready, a full-scale effort to design and build the bombs themselves was begun in spring 1943 at the remote desert location of Los Alamos. The scientific and engineering efforts at Los Alamos were managed by the [[J. Robert Oppenheimer]]. | Groves was bold and willing to spend money.
