Grimaldi, Joseph, a famous English clown, son of an Italian dancing-master, born in London; was bred to the stage from his infancy, appearing on the boards when not yet two years old; his Memoirs were edited by Dickens, who describes him as “the genuine droll, the grimacing, filching, irresistible clown” (1779‒1837).
