(b Geneva, 18 or 19 Aug 1712; d Geneva, 4 Jan 1763). Swiss painter. He studied art in Geneva, Paris and, according to Waterhouse, in Rome. He also travelled to The Hague, where he received commissions from the House of Orange. By December 1743 he was in England, where he soon obtained royal patronage, as for example with his large group portrait of the Children of Frederick, Prince of Wales (1746; Brit. Royal Col.). In 1746 and 1747 he was producing pictures for Frederick, probably including the full-length portraits of Frederick, Prince of Wales and Augusta, Princess of Wales (both Belfast, Ulster Mus.). In 1750 Du Pan was in Dublin, where he painted several portraits, including those of William Stanhope, 1st Earl of Harrington (known from a mezzotint by Michael Ford (d 1765)) and John Boyle, 5th Earl of Orrery (ex-Marston House, Somerset). By August 1751 he had returned to Geneva.
