John Lord founded Deep Purple in 1968, where he was virtually the leader. In addition, Lord wrote the organ riff on "Child in Time". He and drummer Ian Paice were the only constant band members during the band's existence from 1968 to 1976 and from when they reformed in 1984 until Lord's retired in 2002. (9 June 1941 – 16 July 2012)
