J. Robert Oppenheimer, born on April 22, 1904, in New York City, emerged as a preeminent American theoretical physicist of the 20th century. His early career saw groundbreaking contributions to quantum mechanics, establishing his reputation in the scientific community. However, Oppenheimer's most significant role came during World War II, when he served as the scientific director of the Manhattan Project. Leading the Los Alamos Laboratory, he oversaw the successful development of the world's first atomic bombs, which were later used in the bombings of Hiroshima and Nagasaki in 1945. Post-war, Oppenheimer's involvement in the Atomic Energy Commission was marked by tensions due to his opposition to the hydrogen bomb and his association with leftist causes, leading to the revocation of his security clearance in 1954. Despite setbacks, he continued contributing to theoretical physics and academia until his death on February 18, 1967, leaving a complex legacy that encompasses both his pivotal role in nuclear physics and the controversies surrounding his political affiliations.
