Robert Beadell (18 June 1925 – 11 June 1994) was an American composer.
After military service as a bandsman with the United States Marines during the Second World War, Beadell enrolled in the music program at Northwestern University in Evanston, Illinois, where his clarinet teacher, Dominick DiCaprio, encouraged him to study composition. At Northwestern his composition teachers were Robert Delaney and Anthony Donato, and he later studied with Leo Sowerby at the American Conservatory in Chicago, and with Darius Milhaud at Mills College. He first taught music theory and woodwinds at the Swinney Conservatory of Central Methodist College in Fayette, Missouri from 1950 to 1952, then joined the music faculty at the University of Nebraska in Lincoln where he taught from 1954 to 1991 (Smith 2006, 10).
Beadell is best known for his choral compositions and arrangements, and music for jazz ensemble. He also wrote two symphonies, five film scores, song cycles, piano pieces, chamber music, and five stage works: an operetta, The Kingdom of Caraway (1957), a musical, Out to the Wind (1979, based on Willa Cather's short story "Eric Hermannson's Soul"), and three operas, The Sweetwater Affair (1960, produced 1961), The Number of Fools (1965–66, rev. 1976), and Napoleon (1972, produced 1973) (Smith 2006, 12).
