Roger Keith "Syd" Barrett (6 January 1946 – 7 July 2006) was an English singer, songwriter, guitarist, and painter, best remembered as a founder member of the band Pink Floyd. He was the lead vocalist, guitarist, and primary songwriter during the band's psychedelic years, providing major musical and stylistic direction in their early work: he is credited with creating their name. Barrett left the group in April 1968 amid speculations of mental illness exacerbated by drug use, and was briefly hospitalised.
