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.
Edward Teller (Hungarian: Teller Ede; January 15, 1908 – September 9, 2003) was a Hungarian-born American theoretical physicist who is known colloquially as "the father of the hydrogen bomb", although he claimed he did not care for the title. He made numerous contributions to nuclear and molecular physics, spectroscopy (in particular, the Jahn–Teller and Renner–Teller effects) and surface physics.
