English painter whose miniature portraits (miniature painting) in enamel were among the most outstanding produced in Europe in the late 18th and early 19th centuries.

By 1800 the beauty of his portrait pieces had attracted the notice of the Royal Academy, to which he was admitted in 1811. He executed many beautiful miniature pieces of much larger size than had been attempted before in England. Among them are copies of 85 portraits painted during the time of Queen Elizabeth I that are considered among his greatest works. They are displayed at Kingston Lacey, Wimborne Minster, Dorset.
