Wright died Monday after a battle with cancer at his home in Britain. His family did not want to give more details about his death. The spokesman is Doug Wright, who is not related to the artist.
Richard Wright met Pink Floyd members Roger Waters and Nick Mason at college and joined their early band Sigma 6.
Sigma 6 eventually became Pink Floyd and Wright wrote and sang some of the band's key songs. He wrote "The Great Gig In The Sky" and "Us And Them" from Pink Floyd's 1973 "The Dark Side Of The Moon."
He left the group in the early 1980s to form his own band but rejoined Pink Floyd for their 1987 album "A Momentary Lapse of Reason."
