Anthony "Doc" Shiels (born 1938) is a Salford-born artist, magician and writer. After attending the Heatherley School of Fine Art in London, he moved to St Ives, Cornwall where in 1961, following the resignation of Barbara Hepworth, he was made a member of the committee of the influential Penwith Society of Arts. In St Ives he ran the progressive 'Steps Gallery', where he showed artists like Brian Wall and Bob Law. He had several solo exhibitions in London before then leaving St Ives following a drunken incident, in which he threatened police with a gun that he had obtained from painter-friend Terry Frost.
