Walter Keeler's pottery is mainly domestic and functional in salt glazed stoneware or, more rarely, earthenware. He trained at the Harrow School of Art, studying under Victor Margrie and Michael Casson, and later returned there to teach. He set up his first studio in Buckinghamshire in 1965, and has been at his current studio in Penallt in Wales, 10 miles north of the Severn Road Bridge, since 1976.

His influences, he says, are Greek Pottery, Roman Glass, eighteenth century Staffordshire Wares and tin oil cans.
