The decision to develop the atomic bomb was formalized with the establishment of the Manhattan Project in 1942, following concerns that Nazi Germany might be working on similar weapons. The project's initiation was influenced by a letter from physicist Albert Einstein and Leo Szilard to President Franklin D. Roosevelt in 1939, warning of the potential for nuclear weapons. The project ultimately led to the successful detonation of the first atomic bomb in July 1945.
