(b Ruabon, nr. Wrexham, Wales, c.1750 d Wrexham, 24 Dec. 1824). British painter and draughtsman, mainly of portraits. He was a pupil of Benjamin West, before becoming part of the first intake of students at the Royal Academy in 1769. In 1773–5 he visited Italy with Joseph Wright. After his return to England he became a leading fashionable portraitist. His success depended partly on his speed of work, and from the 1780s he relinquished oils in favour of a distinctive technique that enabled him to produce portraits in great quantity, using black chalk lightly tinted with watercolour.
