Douglas Clare Fischer was an American keyboardist, composer, arranger, and bandleader. After graduating from Michigan State University, he became the pianist and arranger for the vocal group the Hi-Lo's in the late 1950s.
Fischer went on to work with Donald Byrd and Dizzy Gillespie, and became known for his Latin and bossa nova recordings in the 1960s. He composed the Latin jazz standard "Morning", and the jazz standard "Pensativa". Consistently cited by jazz pianist and composer Herbie Hancock as a major influence, he was nominated for eleven Grammy Awards during his lifetime, winning for his landmark album, 2+2, the first of Fischer's records to incorporate the vocal ensemble writing developed during his Hi-Lo's days into his already sizable Latin jazz discography; it was also the first recorded installment in Fischer's three-decade-long collaboration with his son Brent. Fischer was also a posthumous Grammy winner for ¡Ritmo! and for Music for Strings, Percussion and the Rest.
