Segr Emilio

Emilio Gino Segrè (1905–1989)

Italian‑American physicist known for the discovery of the antiproton and the 1959 Nobel Prize in Physics.

Biographical overview

• Born February 1, 1905, in Tivoli, near Rome, Italy.
• Studied and began research at the Sapienza University of Rome, working with Enrico Fermi and colleagues on nuclear and particle physics.
• Emigrated to the United States in 1938 after Italy’s racial laws; became a naturalized American citizen and a long‑time faculty member at the University of California, Berkeley.
• Died April 22, 1989, in Berkeley, California.

Key scientific contributions

Segrè’s landmark achievement was the experimental discovery of the antiproton in 1955, carried out with his collaborator Owen Chamberlain at the Bevatron accelerator at UC Berkeley. This work provided strong confirmation of antimatter predicted by theory and earned them the Nobel Prize in Physics in 1959.

Career highlights

• Early research in Rome with Enrico Fermi on neutron interactions and nuclear physics.
• 1938 onward: moved to the United States to continue research and teaching after anti‑Semitic policies in Italy.
• 1960s onward: long‑standing faculty member at the University of California, Berkeley’s physics department and Radiation Laboratory, contributing to experimental nuclear and particle physics.

Awards and legacy

The Nobel Prize in Physics (1959) remains the defining recognition of Segrè’s career. His work helped establish modern experimental particle physics in the postwar era and influenced generations of physicists pursuing antimatter, nuclear reactions, and high‑energy physics.
