Glaser, Donald Arthur

Glaser, Donald Arthur (1926-2013), an American physicist, won the Nobel Prize in physics in 1960 for inventing the bubble chamber. This device is a vital aid in nuclear physics. With it, researchers can track the paths of nuclear particles. It contains liquefied gas. Nuclear particles shot through the liquefied gas leave tracks of tiny bubbles that can be photographed.

Glaser was born on Sept. 21, 1926, in Cleveland. He earned a bachelor’s degree from Case Institute of Technology in 1946 and a Ph.D. degree from the California Institute of Technology in 1950. Glaser taught physics at the University of Michigan at Ann Arbor from 1949 to 1959 when he moved to the University of California at Berkeley. Glaser died on Feb. 28, 2013.
