Emilio Gino Segrè discovered technetium andastatine and antiproton
Emilio Gino Segrè (1 February 1905 – 22 April 1989) was an Italian physicist and Nobel laureate who discovered the elements technetium andastatine, and the antiproton, a sub-atomic antiparticle, for which he was co-awarded the 1959 Nobel Prize in Physics with American Owen Chamberlain. An Antiproton is an antiparticle that has the same mass as a proton but opposite in electrical charge.
He was born in Tivoli, near Rome, and studied engineering at the University of Rome La Sapienza before taking up physics in 1927. Segrè was appointed assistant professor of physics at the University of Rome in 1932 and worked there until 1936. He was Director of the Physics Laboratory at the University of Palermo from 1936 to 1938.
