Arthur Leslie Benjamin was an Australian composer.
Benjamin won a scholarship from Brisbane Grammar School to the Royal College of Music in 1911. After serving in the infantry and the air force during World War I, he became piano professor at the Sydney Conservatorium in 1919. He returned to England in 1921 to become piano professor at the Royal College of Music. Among his students at the Royal College was Benjamin Britten. He died in 1960 of cancer.
Benjamin wrote many operas ("The Devil Take Her", "Prima Donna", and "Mañana"), orchestral works, songs and film scores. His best-known piece is "Jamaican Rumba", composed in 1938, for which the Jamaican government gave him a free barrel of rum a year as thanks for making their country known.
