Artist: (quoted from the National Portrait Gallery)

Sir Thomas Lawrence (1769-1830), Portrait painter, collector and President of the Royal Academy. Artist associated with 425 portraits, Sitter in 13 portraits.

In 1814, Lord Stewart, who had been appointed ambassador in Vienna and was a previous client of Thomas Lawrence, wanted to commission a portrait by him of the Prince Regent (later King George IV). He therefore arranged that Lawrence should be presented to the Prince Regent at a levée. Soon after, the Prince visited Lawrence at his studio in Russell Square. Lawrence wrote to his brother that To crown this honour, [he] engag'd to sit to me at one today and after a successful sitting of two hours, has just left me and comes again tomorrow and the next day. The result was a drawing in the Royal Collection, this dashing oil sketch of his head in profile like a Classical god and a large portrait of him in Field Marshall's uniform.
