Pink Floyd’s founding member Richard Wright has died. He passed away on Monday at the age of 65 after battling cancer, his spokesman said.

"The family of Richard Wright, founder member of Pink Floyd, announces with great sadness, that Richard died today after a short struggle with cancer. The family has asked that their privacy is respected at this difficult time."

It is not known what form of cancer Wright suffered from. He is survived by his third wife Millie, their son Ben, and his two children from his marriage to first wife Juliette Gale.

Wright wrote significant parts of the music for classic albums like “Meddle,” “Dark Side of the Moon” and “Wish You Were Here,” as well as for Pink Floyd's final studio album “The Division Bell.” He was also the band's keyboard player. He mastered a wide range of instruments including the synthesizer and Farfisa organ.

In addition, Wright frequently sang background and occasionally lead vocals on stage and in the studio with Pink Floyd. His voice can be heard in songs like: "Time," "Echoes,” and on Syd Barrett’s composition "Astronomy Domine."

He left the group in the early 1980s to form his own band but rejoined Pink Floyd a few years later, in time for their 1987 album "A Momentary Lapse of Reason." Wright performed with the surviving members of Pink Floyd in 2005 for Live 8. Wright performed regularly with Pink Floyd singer and guitarist David Gilmour over the past three years.
