US Vacates 1954 Security Decision for ‘Father of Atomic Bomb’

The US Energy Department on Friday vacated a decision made in 1954 to revoke the security clearance of J Robert Oppenheimer, the “father of the atomic bomb.”

Oppenheimer died in 1967 from cancer. The scientist played a key role in the Manhattan Project, a large-scale US government effort to create the first nuclear weapons. His security clearance was revoked amid what the Energy Department said was an effort to discredit him.
