Little is documented about William Warman (1806–1875) but he was certainly a professional portraitist working in the early and mid-19th century. There is a watercolour portrait by him of Queen Victoria in the National Portrait Gallery in London (NPG 1891a), which is a reduced copy after Thomas Sully. A lithograph print by Warman in the Ashmolean Museum, Oxford (WAHP9819.2) suggests that his portraits were reproduced as book illustrations.
Warman's skill is impressive and the facial detail to his portraits is executed with the delicate handling of a miniaturist.
