World War 2

After college is when Feynman really started to shine in his field. In 1942 he was asked to join the team that developed the atomic bomb in Los Alamos and Princeton. At first, he said no to helping to create a weapon of such mass destruction... until he thought about how Hitler probably would have no qualms in making a atom bomb. Richard was key in developing safe means to separate various radioactive materials and also ways to test what amount of uranium would be needed to achieve critical mass that did not require large scale detonations.
