J. Robert Oppenheimer was an American theoretical physicist, director of the Manhattan Project which was a World War II. research program by the United States, the United Kingdom and Canada aimed to develop atomic weapons. In Manhattan Project he worked together with physicists like Edward Teller, Felix Bloch, Hans Bethe, and Emil Konopinski to calculate what and in what order it takes to build a fission bomb. After finding out that a gun-type fission bomb with plutonium is impossible to be made, they fully concentrated on uranium bombs and on 16 July, 1945, the first experimental explosion was made on a site near Los Alamos, which Oppenheimer called “Trinity”. In the World War II. on 6 August 1945 a gun-type bomb called “Little Boy” was dropped on Hiroshima, and on 9 August “Fat Man”, an implosion-type atomic bomb, on Nagasaki. Henry Truman awarded Oppenheimer the Medal of Merit in 1946 for his work in Los Alamos. After the war, however, he was closely investigated by the FBI and was accused of sympathizing with the Communists. In the post-war years he continued to teach and research. Among his notable achievements are the Born-Oppenheimer approximation and the Oppenheimer-Phillips process.
