b. 1898 in Haddington, East Lothian; d. 1973. Scottish landscape and still life painter. Studied at Edinburgh College of Art, taught there for over forty years after he graduated. Principal of the College (1959-66). Founded the 1922 Group with nine other students including William Crozier and William MacTaggart. With a travelling scholarship, he studied under Andre Lhote in Paris (1923) and then visited Italy (1924). Worked in a cubist manner but turned back to a more traditional style. Paul Klee influenced Gillies' 1934 work, "The Harbour," where he used bold blocks of contrasting colour. He experimented with portraiture in his early career, but concentrated primarily on landscapes and still lifes, often depicting scenes of the Lothian, Fife and Border regions.
