Royal Academy schools from 1769. He exhibited at the Society of Artists 1765–71 and at the Royal Academy 1772–1807, and became miniature painter to the Duchess of York in 1792 and limner to the Prince Regent in 1803. He was in Edinburgh for several years in the mid 1790s. He is not hitherto recorded as a pastellist, but the allegorical work corresponding to the engravings by George Keating and John Murphy appears, from its combination of colour and detail, to be the source..It may be the work exhibited at the Royal Academy in 1791 (no medium is indicated, but the work is not in the miniatures section)
