The history of the atomic bomb began with the Manhattan Project. It was tasked to create the bomb beginning in 1939. The scientists who invented the bomb included Robert Oppenheimer, Edward Teller, Rudolf Peierls and many others.
Einstein's greatest role in the invention of the atomic bomb was signing a letter to President Franklin Roosevelt urging that the bomb be built. The splitting of the uranium atom in Germany in December 1938 plus continued German aggression led some physicists to fear that Germany might be working on an atomic bomb.
