Patrick Quentin is one of the pseudonyms of Hugh Callingham Wheeler (1912-1987), who collaborated with several other authors on the books written as by Q. Patrick and Jonathan Stagge. Wheeler was born in London but moved to the United States in 1934 and became a U.S. citizen, as did one of his writing partners, Richard Wilson Webb; he also collaborated with Martha (Patsy) Mott Kelly. After producing more than 30 mystery novels, Wheeler gravitated to the stage and wrote the book for A Little Night Music, Candide, and Sweeney Todd, all of which earned him Tony awards. Two Peter Duluth novels inspired films: Homicide for Three (1948) and Black Widow (1954), which starred Van Heflin, Gene Tierney, Ginger Rogers and George Raft. Otto Penzler, the creator of American Mystery Classics, is also the founder of The Mysterious Press (1975); MysteriousPress.com (2011), an electronic-book publishing company; and New York City's Mysterious Bookshop (1979). He has won a Raven, the Ellery Queen Award, two Edgars (for the Encyclopedia of Mystery and Detection, 1977, and The Lineup, 2010), and lifetime achievement awards from NoirCon and The Strand Magazine. He has edited more than 70 anthologies and written extensively about mystery fiction.
