5. Klaus Fuchs (The Bombmaker)
During this period, the Manhattan Project was underway as preparation for World War II. “The Bomb Maker” became a part of the team of scientists carrying out this project for expedition research to manufacture a viable atomic bomb. However, there was a problem as none of these scientists understood Fuchs was Russian spying on them.
In 1949 the Federal Bureau of Investigation (FBI) and the British Intelligence began interrogating the bomb maker, which led him to confessions of his identity. Klaus Fuchs was later convicted of trying to obtain information in a two-day trial.
