J. Robert Oppenheimer, born on April 22, 1904, was the scientific director of the Manhattan Project, the World War II project that developed the first nuclear weapons. He strongly opposed the development of the hydrogen bomb, however, and in 1953 was suspended from secret nuclear research as an alleged communist sympathizer, a case backed by Edward Teller. In 1963 he was reinstated and awarded the Enrico Fermi Award.
Julius Robert Oppenheimer was an theoretical physicist. He is among the persons who are often called the "father of the atomic bomb" for their role in the Manhattan Project. His notable achievements in physics include the Born–Oppenheimer approximation for molecular wavefunctions, work on the theory of electrons and positrons, the Oppenheimer–Phillips process in nuclear fusion, and the prediction of quantum tunneling.
