Jean-Urbain Guérin was a French draughtsman and miniaturist. With Jean-Baptiste Isabey and Jacques Augustin, he is still held to be one of the most notable miniaturists of his time.
Guérin himself wrote in his accounts book that in 1791 he produced a portrait of Georgiana, Duchess of Devonshire, who was a friend of queen Marie-Antoinette. He also painted Marie-Antoinette herself and her husband Louis XVI and drew portraits of several deputies of the third estate in 1785, which were later engraved by Franz Gabriel Fiesinger. After the French Revolution he also painted portraits of several generals of the First French Republic, which were often reproduced, as well as images of Kléber, Napoleon Bonaparte and Mozart.
