William Henry Margetson (1860-1940) is a British painter noted for his pictures of very beautiful girls, typically alone and large on the canvas, and typically with short hair and hats when they are modern subjects.
He studied at the South Kensington Schools, and then at the Royal Academy, exhibiting there from 1885.
He lived at Wallingford on Thames. As well as modern girls and portraits, Margetson also produced a few religious pictures, and some allegorical and classical/ancient ones–for example a Cleopatra, fetchingly attired, with attendants in an Alma-Tadema setting, 1890.
