Fermi, born in September 1901 in Italy, became a naturalized American citizen. The physicist is considered one of the world’s most brilliant and productive scientists. In 1938, he was awarded the Nobel Prize in Physics for his demonstrations of the existence of new radioactive elements produced by neutron irradiation, and for his related discovery of nuclear reactions brought about by slow neutrons. After receiving the Nobel Prize, he joined the faculty of Columbia University before eventually moving to the University of Chicago where he led the first controlled nuclear chain reaction.
