Harry S. Truman
Truman sat in the Oval during two major conflicts, the Second World War and the beginning of the Cold War. He only spent weeks as Vice President of the United States before assuming the top job following Roosevelt’s demise. Truman once told reporters that he felt “like the moon, the stars, and all the planets had fallen on me.” During his term, Truman put his 139.8 IQ to work solving problems in the development of the A-bomb and growing challenges with the Soviets. One of the most defining moments in American history was made when Truman authorized the dropping of atomic bombs on Hiroshima and Nagasaki.
