Preceding Context: In August 1939 Leó Szilárd prepared and Albert Einstein signed the famous letter warning President Franklin D. Roosevelt of the probability that the Nazis were planning to build an atomic bomb. Because of Hitler's September 1 invasion of Poland, it was October before they could arrange for the letter to be personally delivered. Roosevelt was concerned enough that the Uranium Committee was assembled, and awarded Columbia University the first nuclear power funding of US$6,000. However, due to bureaucratic fears of foreigners doing secret research, the money was not actually issued until Szilárd implored Einstein to send a second letter to the president in the spring of 1940. The money was used in studies which led to the first nuclear reactor —
Succeeding Context: , a massive "atomic pile" of graphite bricks and uranium fuel which went critical on December 2, 1942. The pile was built in a squash court under Stagg Field, the football stadium at the University of Chicago. (Due to a mistranslation, Soviet reports said Fermi's work was performed in a converted "pumpkin field" instead of a "squash court", a mis-translation based on confusion between dual meanings of "squash", the food-crop plant and the game.) This experiment was a landmark in the quest for energy, and it was typical of Fermi's brilliance. Every step had been carefully planned, every calculation meticulously done by him. When the first self-sustained nuclear chain reaction was achieved, a coded phone call was made by one of the physicists, Arthur Compton, to James Conant, chairman of the National Defense Research Committee. The conversation was in impromptu code:
