Horton, Percy (1897-1970), artist

Painter and draughtsman, born in Brighton, Sussex. Studied at Brighton School of Art, 1918–20, where he had a scholarship. Horton was a man of strong radical convictions, and because he was an absolute conscientious objector he had to endure two years’ hard labour in Carlton Prison, Edinburgh, 1916–18, during World War I. From 1916–18 was at Central School of Arts and Crafts under A S Hartrick and Ernest Jackson, then with a Royal Exhibition attended Royal College of Art, under Randolph Schwabe and Allan Gwynne-Jones, 1922–5. Horton went on to teach at the Royal College, 1930–49, where he was a highly respected figure, becoming Ruskin Master of Drawing at Oxford University, 1949. Taught voluntarily at the Working Men’s College, London, for a time.
