Editor's Take:

Fermi was that rare physicist who excelled at both theory and experiment. In 1942, in Chicago, his team built the first nuclear reactor, called Chicago Pile-1, achieving the first controlled nuclear chain reaction. This breakthrough opened the way to both nuclear power and the atomic bomb, and he later worked on the Manhattan Project. He had already won the Nobel Prize in 1938 for work on nuclear reactions caused by slow neutrons. He was also famous for 'Fermi problems', making quick, clever estimates from limited information.
