Stanley 'Spike' Glasser (28 February 1926 – 5 August 2018), was a South African-born British composer and academic who studied with Benjamin Frankel and Mátyás Seiber. His concert music was deeply influenced by his ethnomusicological investigations of native African music. The elder son of first-generation Jewish immigrants from Lithuania, he was forced to flee South Africa's apartheid regime in 1963 due to his relationship with black jazz singer Maud Damons.
