Many Scientists came form Europe to create the atomic bomb, because of Hitler and all that. Albert Einstein was the one who first informed Franklin D. Roosevelt about the idea. When Roosevelt died Harry S. Truman (vice president) stepped in. While all of that was happening; they were still in war with Japan. To make Japan surrender; Truman decided to use the atomic bomb against Japan. They first bombed Hiroshima with a uranium bomb they called "Little Boy". Then when Japan still didn't surrender; Truman decided to also bomb Nagasaki. With a plutonium bomb they called "Fat Man". And that's why (:
