'Father of Atomic Bomb' was blacklisted for opposing H-bomb
Robert Oppenheimer, Director of the US-based lab that designed the world's first atom bomb in 1945, opposed Hydrogen bomb's development. Despite his opposition, the US tested the H-bomb on November 1, 1952, which yielded nearly 1,500 times more energy than Hiroshima and Nagasaki bombs combined. In 1953, Oppenheimer was suspended from secret nuclear research and stripped off his security clearance.
