Joseph Allan Dunn (1872-1941), 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 1914-41.
He came to the United States in 1893. He spent about five years in Colorado, five years in Honolulu, ten years in San Francisco, and then relocated to the East Coast in 1913, after which his writing career blossomed. From 1914 forward, and in his pulp-writing career, he was known as "J. Allan Dunn"; before that he primarily went by "Allan Dunn."
While living in San Francisco, he worked for the Southern Pacific Company, which published Sunset magazine. He wrote an article for Sunset on author Jack London. The two became friends. In 1913, Dunn was a frequent visitor to London's Beauty Ranch in Glen Ellen, California. According to the diaries of Charmian London, London's second wife, she and Dunn spent a lot of time together, which prompted Jack London to reinvigorate his interest in her.
