The FBI watched J. Robert Oppenheimer for months after he helped make the WWII-ending atomic bomb. Reports from the FBI show Oppenheimer was accused of Communism and spreading information to Russia. During the investigation, though, Pitzer said he had new doubts about Oppenheimer's loyalty to the country, due to his initial reservations about the development of the H-bomb. The Atomic Heritage Foundation does consider Oppenheimer likely to have held communist sympathies, but maintains that information in the report was exaggerated. At the end of the inquest, Oppenheimer's top-level security clearances were revoked, a devastating blow to the scientist.
