Johnston McCulley was the author of hundreds of stories, fifty novels, numerous screenplays for film and television, and the creator of the character Zorro. Many of his novels and stories were written under the pseudonyms Harrington Strong, Raley Brien, George Drayne, Monica Morton, Rowena Raley, Frederic Phelps, Walter Pierson, and John Mack Stone, among others. Aside from Zorro, McCulley created many other pulp characters, including Black Star, The Spider, The Mongoose, and Thubway Tham. Many of McCulley’s characters—The Green Ghost, The Thunderbolt, and The Crimson Clown—were inspirations for the masked heroes that have appeared in popular culture from McCulley’s time to the present day.
