Born: April 22, 1904, New York Died: February 18, 1967. Princeton. American physicist. After graduating from Harvard University, he studied at Cambridge University in 1925, and studied under E. Rutherford at the Cavendish Laboratory. He moved to the University of Göttingen at the invitation of M. Born, and obtained his doctorate in 1927. After returning to the United States, he became a professor at the University of California and the California Institute of Technology, and during World War II, he directed the Manhattan Project (1943-45). After the war, he became chairman of the General Advisory Committee of the Atomic Energy Commission (AEC) (1946-52), and also served as director of the Advanced Institute at Princeton University (1947-66). In 1949, he argued that the construction of a hydrogen bomb should not be rushed, and this caused a rift in his mind, leading to his expulsion from the AEC in June 1954 for "having previously been in contact with communists" (Oppenheimer Affair). In 1963, the stigma was cleared and the AEC awarded him the Fermi Prize. He made great contributions to the fields of positron theory, particle physics, nuclear theory, and astrophysics, and also contributed to the training of physicists. His philosophical works include Science and the Common understanding (54) and The Open Mind (55). Oppenheimer |
