Donald Maurice Ginsberg (November 19, 1933 – May 7, 2007) was an American physicist and expert on superconductors.
Born in Chicago, Ginsberg attended the University of Chicago, earning a Bachelor of Arts in 1952, a bachelor of science in 1955, and a master of science in 1956. He then earned his doctorate in physics from the University of California, Berkeley in 1960. He taught at the University of Illinois at Urbana-Champaign from 1959 to 1996.
Ginsberg is noted for growing purified metallic crystalline compounds called YBCO. His five-volume Physical Properties of High Temperature Superconductors was influential in the field. He shared the 1998 Oliver E. Buckley Condensed Matter Prize.
He died of melanoma at his home in Urbana, Illinois.
