George Heywood Maunoir Sumner (1853–1940) was originally an English painter, illustrator and craftsman, closely involved with the Arts and Crafts movement and the late-Victorian London art world. In his mid-forties he relocated to Cuckoo Hill, near Fordingbridge in Hampshire, England, and spent the rest of his life investigating and recording the archaeology, geology and folklore of the New Forest and Cranborne Chase regions.
