Richard W. "Dick" Sprang (July 28, 1915 - May 10, 2000) was an American comic book artist and penciller, best known for his work on the superhero Batman during the period fans and historians call Golden Age of Comic Books. Sprang was responsible for the 1950 redesign of the Batmobile and the original design of the Riddler, who has appeared in film, television and other media adaptations. Sprang's Batman was notable for his square chin, expressive face and barrel chest.
