Adolph Sender Charles Deutsch was a British-American composer, conductor and arranger.
Born in London, England, he emigrated to the United States in 1911, and settled in Buffalo, New York. His parents, Alex Deutsch and Dena née Gerst, were German Jews.
In 1914, Deutsch was "a Buffalo movie house musician", accompanying silent films. Deutsch began his composing career on Broadway in the 1920s and 1930s, and arranged for several American dance bands such as Paul Whiteman and Paul Ash before working for Hollywood films beginning in the late 1930s. For Broadway, he orchestrated Irving Berlin's As Thousands Cheer and George and Ira Gershwin's Pardon My English.
Deutsch won Oscars for his background music for Oklahoma!, and for conducting the music for Seven Brides for Seven Brothers and Annie Get Your Gun. He was nominated for The Band Wagon and the 1951 film version of Show Boat, for which he conducted the orchestra. For Broadway and Hollywood, he conducted, composed and arranged music, but did not write songs, not even for the Broadway shows on which he worked.
