Painter, draughtsman and writer, born in Petersfield, Hampshire. He was educated at Churcher’s College and studied privately with an uncle, Frank Patterson, prior to World War I. In 1918 Muirhead Bone offered to get Gammon into the Slade School of Fine Art, but being married he declined, taking up a career as an illustrator and writer. He drew for Punch, cycling and motoring magazines and in the 1930s wrote and illustrated a country feature for the News Chronicle. Made extensive walking and cycling trips in Britain, Ireland and Brittany, painting watercolours. After World War II was a hill farmer in the Black Mountains until 1953, then took up oil painting seriously, settling in Cannington, Somerset. He was influenced by Gauguin, using a rich palette to depict simple rural life.
