The United States Atomic Energy Commission conducted the Oppenheimer security hearing in 1954 to investigate J. Robert Oppenheimer, the scientist who led the development of the atomic bomb during World War II. The hearing resulted in Oppenheimer's security clearance being revoked, ending his formal relationship with the US government. Doubts about Oppenheimer's loyalty stemmed from his association with Communist Party members, including his wife and brother. As director of the Los Alamos Laboratory, Oppenheimer was involved in conflicts between the Army and Air Force, technical disagreements, and personal disputes with AEC commissioner Lewis Strauss. Despite being found loyal and discreet with atomic secrets, Oppenheimer's security clearance was not reinstated. This marked the end of his government career and had broader implications for scientists working in government. The fairness of the proceedings has been a subject of controversy, and in 2022, the decision was nullified by United States Secretary of Energy Jennifer Granholm. J. Robert Oppenheimer was a renowned theoretical physicist before World War II with achievements such as predicting the existence of black holes. He became more well-known during the war when he was brought into the Manhattan Project to develop the atomic bomb, and his fame grew after the bombings of Hiroshima and Nagasaki. He was described as a hero of science and intellect during the atomic age. Oppenheimer had many Communist Party USA associates and the FBI had a file on him since 1941. In 1943, Oppenheimer was approached by Chevalier with an offer to pass information to the Soviet Union, but he rejected it and waited until August to report it. The shifting nature of Oppenheimer's accounts and the 1943 fabrication were important factors in the 1954 inquiry. Oppenheimer faced conflict with political enemies who obtained incriminating evidence about his Communist ties. He was humiliated by AEC commissioner Lewis Strauss and called before the Joint Committee on Atomic Energy. Oppenheimer also faced controversy over his association with Communist Party members and was forced to testify in front of the House Un-American Activities Committee. Additionally, he was involved in the development of the "Super" bomb and pushed for smaller tactical nuclear weapons. Despite conflicts, Oppenheimer continued to work for the government. In 1953, J. Edgar Hoover received a letter from William Liscum Borden stating his belief that J. Robert Oppenheimer was an agent of the Soviet Union. The letter outlined evidence including Oppenheimer's connections to communism, his involvement in recruiting Communists, and his opposition to the development of the hydrogen bomb and postwar atomic energy projects. Despite the lack of new evidence, President Eisenhower ordered that Oppenheimer be kept away from the nation's atomic secrets.
