Enrico Fermi, born in Italy in 1901, was one of the major figures of twentieth century physics. He discovered the statistical law governing the class of subatomic particles which includes electrons, protons and neutrons. His experiments with nuclear bombardment led to the discovery of nuclear fission, and ultimately to the first controlled nuclear chain reaction. Fermi won the Nobel Prize in Physics for his work on the artificial radioactivity produced by neutrons.
