After he wrote several comic-books, Dick Sprang sought to continue his career as a cartoonist, so he submitted art-samples to editor Whitney Ellsworth, who assigned him to a Batman story in 1941. Therefore, Dick Sprang became one of the primary Batman cartoonists in the character's first 20 years. In 1995, however, Dick Sprang stopped writing Batman comics and went onto Superman. Dick Sprang was also uncredited ghost artist on Batman until the 1960s, in which decade it was revealed that he was Bob Kane's favorite "ghost."
