National Medal of Arts, Pulitzer Prize, and Grammy Award-winner William Bolcom (born May 26, 1938) is an American composer of chamber, operatic, vocal, choral, cabaret, ragtime, and symphonic music.

He joined the faculty of the University of Michigan's School of Music in 1973, was named the Ross Lee Finney Distinguished University Professor of Composition in 1994, and retired in 2008 after 35 years.  Bolcom won the Pulitzer Prize for music in 1988 for 12 New Etudes for Piano, and his setting of William Blake's Songs of Innocence and Songs of Experience on the Naxos label won four Grammy Awards in 2005.

As a pianist Bolcom has performed and recorded his own work frequently in collaboration with his wife and musical partner, mezzo-soprano Joan Morris.  Cabaret songs, show tunes, and American popular songs of the 20th century have been their primary specialties in both concerts and recordings.  Their 25th album,  "Autumn Leaves," was released in 2015.
