Centaur developed primarily from the Comics Magazine Company, Inc. In 1936, comic-book entrepreneur Everett M. "Busy" Arnold gave financial or other unspecified help to that New York City-based firm, founded by John Mahon and Bill Cook, former employees of Major Malcolm Wheeler-Nicholson's National Allied Publications (the primary forerunner of DC Comics). The duo published the premiere issue of The Comics Magazine (May 1936), using inventory content from National Allied's submissions. (One collector/historian suggests this was in lieu of pay.)
Among the Comics Magazine Company's original features was Dr. Mystic the Occult Detective (not to be confused with Mr. Mystic of newspapers' "The Spirit Section"). This two-page feature was by future Superman creators Jerry Siegel and Joe Shuster, and was part of their Doctor Occult continuity, with the name changed for trademark consideration. This was the beginning of a serial that introduced the villain Koth, and the Seven, that continued into DC's More Fun Comics #14-17 (issues also designated as vol. 2 #2-5).
The company's flagship title, the eponymous Comics Magazine, premiered with a May 1936 cover date. That comic-book series featured the first masked hero in American comics, writer-artist George Brenner's the Clock, in the November 1936 issue.
Another entrepreneur, Harry "A" Chesler, published Star Comics and Star Ranger through his own Chesler Publications, each with first issues cover-dated February 1937. These titles were soon bought out by I. W. Ullman and Frank Z. Temerson's Ultem Publications. In September 1937, Ultem acquired the Comics Magazine Company's titles, retaining Chesler as the packager for both his own previous titles and the two that were continued from the Comics Magazine Co. Financial difficulties forced Ultem to sell some of its properties, including the Clock, to "Busy" Arnold's Quality Comics.
By January 1938, Ultem was bought out by Joe Hardie, Fred Gardner, and Raymond Kelly's Centaur Publications, Inc., which had been publishing pulp magazines since at least 1933. Hardie, Gardner, and Kelly used this base to create Centaur Comics, which began publishing in March 1938. They also drew on the back inventory of stories to fill out the early issues of their new titles with reprints. Centaur Publications, Inc. ceased production at the end of 1940, but continued to produce comics under the name Comic Corporation of America.
Centaur ceased publication four years later, primarily due to poor distribution, but in that period had created several colorful characters, including Bill Everett's Amazing Man. Everett would later go on to comics fame by introducing Namor The Submariner to Timely (later Atlas, then Marvel Comics.) Everett's first nationally published comic work was the cover of Amazing Mystery Funnies #1 (1938.)
In 1992, Malibu Comics revived several Centaur heroes—which by that time had lapsed into public domain—as the superhero team The Protectors. Included were Airman, Amazing Man, the Arrow, the Clock (as a retired mystery man, then the President of the United States, Brian O'Brien), the Fantom of the Fair, also known as Fantoman (renamed by Malibu as Gravestone), the Ferret, Man of War, the Masked Marvel (renamed Night Mask), Mighty Man, Prince Zardi the Eternal Man, and the Shark (renamed Thresher), as well as completely original characters, such as Arc and Aura. Several of these characters had short-lived titles of their own.
