Here is the revised memorial biography of J. Robert Oppenheimer, refined to include only well-supported, verified facts drawn from reliable sources.

Julius Robert Oppenheimer was born on April 22, 1904, in New York City, into a prosperous, assimilated Jewish family. His father, Julius S. Oppenheimer, was a German immigrant who became a successful textile importer; his mother, Ella (née Friedman), was a painter. The family home on Riverside Drive was furnished with notable European artwork, reflecting their cultural engagement (en.wikipedia.org). Oppenheimer attended the Ethical Culture School in New York, graduating in 1921 (ias.edu).

He entered Harvard University in 1922, earning a bachelor's degree in chemistry in 1925 (en.wikipedia.org). He then moved to Europe for doctoral studies, receiving his Ph.D. in physics from the University of Göttingen in 1927 under the supervision of Max Born (en.wikipedia.org).

Upon returning to the United States, Oppenheimer joined the faculty of the University of California, Berkeley, becoming a full professor by 1936 (en.wikipedia.org). He made significant contributions to theoretical physics, including the Born–Oppenheimer approximation and the Oppenheimer–Phillips process in nuclear physics, and advanced work in quantum mechanics, quantum electrodynamics, and the theory of neutron stars and black holes (en.wikipedia.org).

During World War II, in 1942 Oppenheimer was appointed director of the Los Alamos Laboratory, where he led the scientific team that developed the first atomic bombs as part of the Manhattan Project. He witnessed the successful Trinity test on July 16, 1945 (en.wikipedia.org). After the war, he served as the chairman of the General Advisory Committee to the U.S. Atomic Energy Commission and, in 1947, became director of the Institute for Advanced Study in Princeton, New Jersey (history.state.gov).

In 1954, at the height of the Red Scare, Oppenheimer’s security clearance was revoked following AEC hearings concerning his past associations and stance on nuclear policy—a decision that ended his formal influence in government (en.wikipedia.org). In December 1963, he received the prestigious Enrico Fermi Award in recognition of his contributions to theoretical physics (biography.com).

Oppenheimer died in his sleep on February 18, 1967, at his home in Princeton, New Jersey, following a battle with throat cancer (en.wikipedia.org). His ashes were later scattered at sea (en.wikipedia.org).
