Iain MacNab was born in Iloilo in the Philippines; he studied at Glasgow School of Art and Heatherley’s School of Fine Art, London. He became owner and principal of the Grosvenor School of Modern Art in London, and was influential in spreading the practice of wood engraving and in fostering the development of linocut printmaking. The school encouraged students’ individuality and allowed them to join for whatever length of time they chose; it attracted passing visitors from abroad and thus its ideas and activities were carried abroad in their turn. In 1938 he published The Student’s Book of Wood Engraving. His work shows clarity of form and composition in a vaguely Vorticist manner.
