J. Robert Oppenheimer Cleared of ‘Black Mark’ After 68 Years
In April and May of 1954, after 19 days of secret hearings, the Atomic Energy Commission revoked Oppenheimer’s security clearance. The action blocked Oppenheimer’s access to the government’s atomic secrets and brought his career to a humiliating end. Until then a hero of American science, he lived out his life a broken man and died in 1967 at the age of 62.
