Malcolm Benjamin Graham Christopher Williamson, AO, CBE (21 November 1931 – 2 March 2003) was an Australian composer. He was the Master of the Queen's Music from 1975 until his death. 　　Williamson was born in Sydney in 1931; his father was an Anglican priest, Rev George Williamson. He studied composition and horn at the Sydney Conservatorium of Music. His teachers included Eugene Goossens. In 1950 he moved to London where he worked as an organist, a proofreader, and a nightclub pianist. In 1952 he converted to Roman Catholicism. From 1953 he studied with Elisabeth Lutyens and Erwin Stein. His first major success was with his Piano Concerto No. 1, premiered by Clive Lythgoe at the 1958 Cheltenham Festival to a standing ovation. Williamson was a prolific composer at this time, receiving many commissions and often performing his own works, both on organ and piano.
