Erle Stanley Gardner (1889-1970) was a prolific American author best known for his works centered on the lawyer-detective Perry Mason. At the time of his death in March of 1970, in Ventura, California, Gardner was "the most widely read of all American writers" and "the most widely translated author in the world," according to social historian Russell Nye. The first Perry Mason novel, The Case of The Velvet Claws , published in 1933, had sold twenty-eight million copies in its first fifteen years. In the mid-1950s, the Perry Mason novels were selling at the rate of twenty thousand copies a day. There have been six motion pictures based on his work and the hugely popular Perry Mason television series starring Raymond Burr, which aired for nine years and 271 episodes. Otto Penzler , the creator of American Mystery Classics, is also the founder of the Mysterious Press (1975); Mysterious Press.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 80 anthologies and written extensively about mystery fiction.
