Robert Edge Pine was an English portrait and historical painter, born in London. He was the son of John Pine, the engraver and designer.
He painted portraits, such as those of George II, of the Duke of Northumberland, and of Garrick; a series of scenes from Shakespeare, some of which afterward appeared in Boydell's Shakespeare; and historical compositions, including Lord Rodney Aboard the Formidable. It is thought that Pine gave lessons to Prince Demah in London.
Pine was active in the society of artists and learned gentlemen in London, in particular the circle of the anatomist, William Hunter. Pine painted Hunter, Hunter's sister, Dorothy Baillie, and Baillie's husband, Prof. Rev. James Baillie. Pine also painted a vibrant portrait of the Captain William Baillie.
Pine held radical political opinions; he painted John Wilkes, MP, during his imprisonment and political exile, and his unfashionable views likely led to his exclusion from the founding group of the Royal Academy of Art in 1768. Nevertheless, Pine did exhibit at the Royal Academy in 1772, 1780, and 1784.
