Wheeler-Nicholson's next 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 that revolved originally on fictional detective stories became in modern times the longest-running ongoing comic series. A notable debut in the first issue was Slam Bradley created in contribution by Malcom-Wheeler-Nicholson, Jerry Siegel and Joe Shuster. 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 to publish "Detective Comics" No. 1. Detective Comics, Inc. (which would help inspire the abbreviation DC) 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.
