Owen Chamberlain

Owen Chamberlain (July 10, 1920 – February 28, 2006) was a prominent American physicist. He shared the Nobel Prize in Physics for 1959 with his collaborator Emilio Segrè for their discovery of the antiproton, a fundamental particle. Owen Chamberlain; Courtesy of http://www. ...

Born in San Francisco, Chamberlain graduated from Germantown Friends School in Philadelphia in 1937. He studied physics at Dartmouth College (A.B. 1941), where he was a member of Theta Chi Fraternity, and at the University of California, Berkeley. He remained in school until the outbreak of World War II. He later joined the "Manhattan Project" in 1942, where he worked with Segrè, both at Berkeley and in Los Alamos, New Mexico.

In 1946, after the war, Chamberlain continued with his doctorate work at the University of Chicago under legendary physicist Enrico Fermi. Fermi acted as an important guide and mentor for Chamberlain, encouraging him to leave behind the more prestigious theoretical physics for experimental physics, for which Chamberlain had a particular aptitude. Chamberlain officially received his Ph.D. from the University of Chicago in 1949. The University of Chicago is a private university located principally in the Hyde Park neighborhood of Chicago. ...

In 1948, having finished his experimental work, Chamberlain returned to Berkeley as a member its faculty (promoted to professor of physics in 1958), where he, Segrè, and other physicists investigated proton-proton scattering. In 1955, a series of proton scattering experiments led to the discovery of the anti-proton, a particle exactly like a proton except negatively charged. Chamberlain's later research work included the Time projection chamber (TPC), and work at the Stanford Linear Accelerator Center (SLAC). In physics, a time projection chamber is a particle detector consisting of a gas-filled cylindrical chamber with multiwire proportional chambers (MWPC) as endplates. ...

Chamberlain was also politically active on issues of peace and social justice, and spoke out against the Vietnam War. He was an influential member of Scientists for Sakharov, Orlov, and Shcharansky, three physicists of the Soviet Union imprisoned for their political beliefs. In the 1980s, he helped found the nuclear freeze movement. Image File history File links Owen_Chamberlain_ID_badge. ... Los Alamos National Laboratory, aerial view from 1995. ...

Chamberlain was diagnosed with Parkinson's disease in 1985, and retired from teaching in 1989. He died of complications from the disease on February 28, 2006, in Berkeley at the age of 85.
