Scientist knew that the atomic could be split. The only thing that Einstein wrote the President was that Germany had a number of scientists working on an atomic bomb.
In July 1939 Albert Einstein sent a letter to President Roosevelt informing him of German atomic research and the potential for a bomb. This letter prompted Roosevelt to form a special committee to investigate the military implications of atomic research. This committee worked under the name 'The Manhatten Project' and the chief scientist involved in developing the first atomic bomb was Robert Oppenheimer.
