Efrem Zimbalist (April 9, 1889-February 22, 1985) was one of the world’s most prominent violinists, as well as a composer and conductor.

After graduation he debuted in Berlin (playing Johannes Brahms' concerto) and London in 1907 and in the US in 1911, with the Boston Symphony Orchestra. He then settled in the US.

He married prominent soprano Alma Gluck and they toured together for a time. Their son, Efrem Zimbalist Jr., and granddaughter, Stephanie Zimbalist, became popular actors. Gluck died in 1935.

In 1928, Zimbalist began teaching at the Curtis Institute of Music in Philadelphia. In 1938 he married the school’s founder, Mary Louise Curtis Bok . He was director of the school from 1941 to 1968. His pupils included Oscar Shumsky.

He retired as a violinist in 1949, but returned in 1952 to give the first performance of the concerto by Gian Carlo Menotti, which is dedicated to him. He retired again in 1955. He served as a juror of the Tchaikovsky piano competition in 1962 and 1966.
