George Gershwin, orig. Jacob Gershvin, (born Sept. 26, 1898, Brooklyn, N.Y., U.S.—died July 11, 1937, Hollywood, Calif.), U.S. composer. Born to Russian-Jewish immigrants, he heard jazz performed live from about age six. In his teens he worked as a song plugger (playing piano in Tin Pan Alley to demonstrate sheet music for potential customers), and in 1916 he published his first song. In 1919 his “Swanee” was performed by Al Jolson and achieved extraordinary success.

Gershwin’s first complete score was for the show La, La Lucille (1919). The bandleader Paul Whiteman commissioned from him the hugely successful orchestral work Rhapsody in Blue (1924). It was revolutionary for its incorporation of the jazz idiom (blue notes, syncopated rhythms, onomatopoeic instrumental effects) into a symphonic context.

Gershwin’s first major Broadway success, Lady, Be Good! (1924), was a collaboration with his brother, lyricist Ira Gershwin. They soon established themselves as one of the great teams in Broadway history; their shows included Oh, Kay! (1926), Strike Up the Band (1927), Funny Face (1927), Girl Crazy (1930), and the satire Of Thee I Sing (1931), the first musical to win a Pulitzer Prize. He also scored several successful films.

His most ambitious work was the “folk opera” Porgy and Bess (1935), a collaboration with Ira and novelist DuBose Heyward. Gershwin’s classical compositions include a piano concerto (1925) and the tone poem An American in Paris (1928). His early death was the result of a brain tumour.
