Robert Steinberg (May 25, 1922, Soroca, Bessarabia, Romania (present-day Moldova) - May 25, 2014 ) was a mathematician at the  University of California, Los Angeles.
He introduced the
Steinberg representation, the Lang-Steinberg theorem, the Steinberg group in algebraic K-theory, Steinberg's formula in representation theory, and the Steinberg groups in Lie theory that yield finite simple groups over finite fields.
Steinberg's parents settled in
Canada very soon after his birth.
Steinberg studied under
Richard Brauer and he received his Ph.D. in mathematics from the University of Toronto in 1948. Steinberg joined the Mathematics Department at UCLA the same year. He retired from UCLA in 1992.
Steinberg was an
invited speaker at the International Congress of Mathematicians in 1966, won the Steele Prize in 1985, was elected to the United States National Academy of Sciences in 1985, and won the Jeffery-Williams Prize in 1990. In 2003, the published a special issue to celebrate Robert Steinberg's 80th birthday.
