Isaac Lee Hayes, Jr. was an American songwriter, musician, singer, actor, and voice actor. Hayes was one of the creative influences behind the southern soul music label Stax Records, where he served both as an in-house songwriter and as a record producer, teaming with his partner David Porter during the mid-1960s. Hayes, Porter, Bill Withers, the Sherman Brothers, Steve Cropper, and John Fogerty were inducted into the Songwriters Hall of Fame in 2005 in recognition of writing scores of notable songs for themselves, the duo Sam & Dave, Carla Thomas, and others.
The hit song "Soul Man", written by Hayes and Porter and first performed by Sam & Dave, has been recognized as one of the most influential songs of the past 50 years by the Grammy Hall of Fame. It was also honored by The Rock and Roll Hall of Fame, by Rolling Stone magazine, and by the RIAA as one of the Songs of the Century.
During the late 1960s, Hayes also began recording music and he had several successful soul albums such as Hot Buttered Soul and Black Moses. In addition to his work in popular music, he worked as a composer of musical scores for motion pictures.
He is well known for his musical score for the film Shaft. For the "Theme from Shaft", he was awarded the Academy Award for Best Original Song in 1972. He became the third African-American, after Sidney Poitier and Hattie McDaniel, to win an Academy Award in any competitive field covered by Academy of Motion Picture Arts and Sciences. He also won two Grammy Awards for that same year. Later, he was given his third Grammy for his music album Black Moses.
