Harry S. Truman (23rd US President) succeeded to the office on April 12, 1945 when Franklin D. Roosevelt died.
Although both FDR and Truman had classified knowledge of the Manhattan Project, no decision could be made on the use of any A-bombs until they were shown to actually work. The first nuclear detonation came on July 16, 1945, two months after FDR died, and it was Truman's decision to actually employ them to force the surrender of Japan. Hiroshima was struck on August 6 and Nagasaki on August 9.
