A. Wyn (born Aaron Abraham Weinstein, May 22, 1898 – November 3, 1967) was an American publisher.
Hersey's swastika logo was dropped to be replaced by an ace of spades playing card symbol.
Assisted by his wife, Rose Schiffman Wyn, whom he had married in 1926, he produced titles such as Detective-Dragnet (later changed to Ten Detective Aces), Western Trails, Secret Agent X, and Love Fiction Monthly.
Titles included Super-Mystery Comics, Four Favorites, Crime Must Pay the Penalty, and Baffling Mysteries.
The first letters of each chapter's title in the book's table of contents, when lined up, spell out "A.A. Wyn is a tightwad".
In 1966, he contributed $50,000 to the New York Federation of Reformed Synagogues in support of a Counseling Center for Teenage Drug Addicts.
