Sheldon Mayer was an American comics artist, writer, and editor. One of the earliest employees of Major Malcolm Wheeler-Nicholson's National Allied Publications, Mayer produced almost all of his comics work for the company that would become known as DC Comics.

Major Malcolm Wheeler-Nicholson, born as Malcolm Strain on 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. Historian and author David Hajdu credits Wheeler-Nicholson as "the link between the pulps and what we know of as comics today." He launched the magazine comics company National Allied Publications in 1934, which would evolve to become DC Comics, one of the United States' two largest comic book publishers along with rival Marvel Comics. He was a 2008 Judges' Choice inductee into the Will Eisner Comic Book Hall of Fame.
