Enrico Fermi

On September 29, 1901, in Rome, Italy, Enrico Fermi was born into a family that encouraged precision, mathematics, and scientific curiosity. He studied at the Scuola Normale Superiore in Pisa, became one of Europe's leading physicists, and won the Nobel Prize in 1938 for work on induced radioactivity. Fascism and anti-Jewish laws pushed him to leave Italy for the United States that same year.

At Columbia University and then the University of Chicago, Fermi became a central figure in the Manhattan Project. On December 2, 1942, beneath the stands of Stagg Field, he directed Chicago Pile-1, the first controlled nuclear chain reaction. His work joined theoretical physics to military research, industrial mobilization, and the strategic transformation of World War II.

Fermi's achievements opened the path to nuclear weapons, nuclear reactors, and the institutions of postwar atomic science. The Atomic Energy Commission, Cold War arms policy, and later civilian nuclear power all developed in the scientific world he helped create.
