Historical Note

The laboratory was founded as the University of California Radiation Laboratory in 1931 by Ernest Orlando Lawrence, a University of California Berkeley physicist who won the 1939 Nobel Prize in physics for his invention of the cyclotron, a circular particle accelerator that opened the door to high-energy physics. It is a United States Department of Energy National Laboratory, operated by the University of California. The name of the laboratory has evolved since its founding: Lawrence Radiation Laboratory (1931-1958), the Lawrence Berkeley Laboratory (1959-1995), and currently the Lawrence Berkeley National Laboratory (1995-present).

Emilio Gino Segrè (1905-1989) was an Italian physicist and Nobel laureate in physics. He was awarded his Ph.D. in physics from the University of Rome in 1928, studying under Enrico Fermi. He was then an assistant professor of physics, University of Rome (1932-1936); director of the Physics Laboratory, University of Palermo (1936-1938); research assistant, Berkeley Radiation Lab and lecturer in the physics department, University of California, Berkeley; Los Alamos National Laboratory, group leader for the Manhattan Project (1943-1946); and a professor of physics and history of science at the University of California, Berkeley (1946-1972).

Scope and Contents of Collection

These records document the technical papers maintained by Noble Laureate Emilio Segrè. The documents include: charts, graphs, correspondence, black and white photographs, diagrams, notes, calculations, and original, annotated reports on spontaneous fission, neutron experiments, and the discovery of the antiproton. In 1959, Emilio Segrè and Owen Chamberlain shared the Nobel prize in physics for the discovery of the antiproton.
