Answer: Robert Oppenheimer was an American physicist who directed the Manhattan Project, the research and development program that created the first atomic bombs during World War II.
Explanation: Robert Oppenheimer was born in New York City in 1904 to a wealthy Jewish family. He studied physics at Harvard University, where he graduated in 1925. He then pursued his PhD at the University of Cambridge and the University of Göttingen, where he worked with some of the leading physicists of his time, such as Max Born and Niels Bohr. He became an expert in quantum mechanics and nuclear physics, and made important contributions to these fields.
In 1929, Oppenheimer returned to the United States and became a professor of physics at the University of California, Berkeley, and the California Institute of Technology. He established himself as a brilliant and influential teacher and researcher, attracting many talented students and collaborators. He also became interested in politics and social issues, and joined various left-wing causes and organizations.
In 1939, after the outbreak of World War II in Europe and the discovery of nuclear fission, Oppenheimer became involved in the efforts to develop an atomic bomb for the United States. He was recruited by the Manhattan Project, the secret military project that aimed to produce a nuclear weapon before Nazi Germany. In 1943, he was appointed as the director of the Los Alamos Laboratory in New Mexico, where he oversaw the design, construction, and testing of the atomic bombs.
Oppenheimer was a charismatic and inspiring leader who managed to coordinate a team of thousands of scientists, engineers, technicians, and military personnel. He also faced many technical, logistical, ethical, and personal challenges during his tenure. He was responsible for choosing the sites for the bomb tests and the targets for the bomb attacks. He witnessed the first successful detonation of an atomic bomb at the Trinity test on July 16, 1945. He later recalled that he thought of a verse from the Hindu scripture Bhagavad Gita: “Now I am become Death, the destroyer of worlds.”
Oppenheimer was also involved in the decision to use the atomic bombs on Hiroshima and Nagasaki in August 1945, which resulted in the deaths of hundreds of thousands of Japanese civilians and the end of World War II. He later expressed mixed feelings about his role in the project, saying that he felt both pride and remorse for his actions.
After the war, Oppenheimer became a prominent figure in the scientific and political arenas. He was appointed as the chairman of the General Advisory Committee of the Atomic Energy Commission, which advised the government on nuclear policy and research. He advocated for international control of nuclear weapons and opposed the development of the hydrogen bomb. He also supported scientific education and cooperation, and became the director of the Institute for Advanced Study in Princeton.
However, Oppenheimer also faced criticism and hostility from some sectors of the government and military who viewed him as a security risk and a communist sympathizer. In 1954, he was accused of disloyalty and subjected to a humiliating hearing that stripped him of his security clearance and his position as a government adviser. The hearing damaged his reputation and career, and caused him much distress.
Oppenheimer spent his later years working on various scientific and cultural projects. He received several honors and awards for his contributions to science and society, including the Enrico Fermi Award in 1963. He died of throat cancer in 1967 at the age of 62.
