query: Who started DC Comics?
passage: Malcolm Wheeler-Nicholson
Malcolm Wheeler-Nicholson (January 7, 1890[1] – 1965)[2] was an American pulp magazine writer and entrepreneur who pioneered the American comic book, publishing the first such periodical consisting solely of original material rather than reprints of newspaper comic strips. Long after his departure from the comic book company he founded, Wheeler-Nicholson's National Allied Publications would evolve into DC Comics, one of the U.S.'s two largest comic book publishers along with rival Marvel Comics.
passage: DC Comics
Wheeler-Nicholson's third and final title, "Detective Comics", advertised with a cover illustration dated December 1936, eventually premiered three months late with a March 1937 cover date. The themed anthology series would become a sensation with the introduction of Batman in issue #27 (May 1939). By then, however, Wheeler-Nicholson had gone. In 1937, in debt to printing-plant owner and magazine distributor Harry Donenfeld—who also published pulp magazines and operated as a principal in the magazine distributorship Independent News—Wheeler-Nicholson had to take Donenfeld on as a partner in order to publish "Detective Comics" #1. Detective Comics, Inc. was formed, with Wheeler-Nicholson and Jack S. Liebowitz, Donenfeld's accountant, listed as owners. Major Wheeler-Nicholson remained for a year, but cash-flow problems continued, and he was forced out. Shortly afterwards, Detective Comics, Inc. purchased the remains of National Allied, also known as Nicholson Publishing, at a bankruptcy auction.
