Segrè

Segrè is an Italian surname. The best known bearer is Emilio Gino Segrè (1905–1989), an Italian‑American experimental physicist and Nobel laureate. Born in Tivoli, Italy, Segrè studied at the University of Rome and worked with Enrico Fermi before leaving Italy in 1938 due to anti-Semitic laws. He joined the physics community in the United States, becoming a leading figure at the University of California, Berkeley. In 1955, Segrè and Owen Chamberlain reported the discovery of the antiproton, the antiparticle of the proton, observed in high-energy proton collisions. The discovery provided important confirmation of particle-antiparticle symmetry and antimatter concepts. For this work, Segrè and Chamberlain were awarded the Nobel Prize in Physics in 1959. Segrè's subsequent research contributed to nuclear and particle physics, including investigations of antinuclei and the properties of matter at high energies. The Segrè surname remains associated with Italian heritage and scientific achievement, and it is sometimes written without diacritical marks as Segre.
