Born in Kilbarchan, Renfrewshire in 1924, Angus saw active duty during WWII. Upon demobilisation he enrolled in the Hostpitalfield School of Art, Arbroath, in 1947; here he was to meet fellow artist, Joan Eardley. Subsequently gaining a place at Glasgow School of Art, that meeting and enduring friendship with Joan was to have a profound impact upon Angus. He and Joan became close friends, working together in the poverty of Glasgow, capturing the children of the slum areas. His work is held in many public and private collections, and along with the work of Joan, remains a powerful depiction of the children of Glasgow of the 1950s and 60s.
