(b Paris, 31 Jan. 1861; d Offranville, 30 Sept. 1942). French painter. The son of Émile Blanche, a noted pathologist, he grew up in a cultured home and became a well-known figure in artistic and society circles—he was a friend of Degas, Renoir, Whistler, the writers Henry James and Marcel Proust, and many other celebrities. His best-known works are stylish portraits of people from this milieu; the finest collection is in the Musée des Beaux-Arts at Rouen, and there are several examples in London (Tate).
