Joseph Allan Elphinstone Dunn (21 January 1872 – 25 March 1941), best known as J. Allan Dunn, was one of the high-producing writers of the American pulp magazines. He published well over a thousand stories, novels, and serials from 1914 to 1941. He first made a name for himself in Adventure.[1] At the request of Adventure editor Arthur Sullivant Hoffman, Dunn wrote Barehanded Castaways, a novel about people trapped on a desert island which was intended to avoid the usual cliches of such stories. Barehanded Castaways was serialised in 1921 and was well received by Adventure's readers.[2][3] Well over half of his output appeared in Street & Smith pulps, including People's, Complete Story Magazine, and Wild West Weekly. Dunn wrote over a thousand stories.[1] He wrote approximately 470 stories for Wild West Weekly alone. His main genres were adventure and western; although he did write a number of detective stories, most of them appearing in Detective Fiction Weekly and Dime Detective.[3] Dunn wrote The Treasure of Atlantis, a science fiction story about survivals from Atlantis living in the Brazilian jungle. The Treasure of Atlantis was published in All-Around Magazine in 1916 and later reprinted in 1970.[4] He was a specialist in South Sea stories, and pirate stories. He also published a lot of juvenile fiction; including many stories for Boys' Life, primarily in the 1920s. A number of his novel-length stories were reprinted in hardbound, some under the pen name "Joseph Montague" for Street & Smith's Chelsea House imprint; many of his books were issued in the United Kingdom. His stories were frequently syndicated in newspapers, both in America and around the world, making him, for a time, a very widely known author.
