Joan Kahn (April 13, 1914 – October 12, 1994) was a New York City-based American author, anthologist, and editor, widely regarded as the preeminent mystery/suspense editor of her time. Described variously as the "doyenne of suspense," "the doyenne of mystery editors," and "publishing's grande dame of detective stories," Kahn first came to prominence during her extended reign (1946-1980) at Harper & Brothers (later Harper & Row), much of it spent creating and overseeing the longstanding "Harper Novel of Suspense" series. The Joan Kahn imprint, instituted during her Harper tenure, soon became a sought-after imprimatur for mystery connoisseurs. Some of Kahn's more celebrated signings include John Creasey, Patricia Highsmith, Julian Symons, Dick Francis, and Tony Hillerman.
