Andrew Welsh Imbrie (April 6, 1921 – December 5, 2007) was an American composer of contemporary classical music.
Imbrie was born in New York on April 6, 1921, and began his musical training as a pianist when he was 4. In 1937, he went to Paris to study briefly with Nadia Boulanger. He returned to the United States the next year to attend Princeton University where he studied with Roger Sessions, receiving his undergraduate degree in 1942. His senior thesis there, a string quartet, was recorded by the Juilliard Quartet. He then went to the University of California, Berkeley, where he received an M.A. in Music in 1947; there he continued to study with Sessions, who had taken a position at Berkeley. Imbrie taught composition, theory, and analysis at Berkeley from 1949 until his retirement in 1991. In addition to his principal teaching job at Berkeley, he served as a visiting professor at the University of Chicago, Brandeis University, Northwestern University, New York University, the University of Alabama, and Harvard University, and had a regular teaching post at the San Francisco Conservatory. He died at his home in Berkeley, California at the age of 86. His notable students included Larry Austin, Neil Rolnick and Leslie Wildman.
