What had Einstein to do with the construction of the atomic bomb?
Frightened that Germany worked on the development of the atomic bomb, Albert Einstein signed a letter to the American president Franklin D. Roosevelt on August 2, 1939 to point out the possibility of an atomic danger to him. In the letter indicated to the president that there was a military threat with atomic energy and gave him the tip, that also the US should increase its nuclear research. This was the only part Einstein played in connection with the atomic bomb! In a letter to his long-time friend Max von Laue Einstein wrote in March 1955: “…The thing with the atomic bomb and Roosevelt was restricted to the fact that I have signed a letter by Szilards facing the danger that Hitler could be in possession of the atomic bomb first. If I had known that this danger was not real, I would not have participated in opening Pandoras box, by the way as little as Szilard.
