While his science fiction and fantasy stories appeared in such pulps as Astounding Stories, Startling Stories, Unknown and Strange Stories, he is best remembered as one of the most popular contributors to the legendary Weird Tales, and for his fantasy and horror stories set in the Appalachian Mountains, which draw on the native folklore of that region. Wellman also wrote in a wide variety of other genres, including historical fiction, detective fiction, western fiction, juvenile fiction, and non-fiction. Karl Edward Wagner referred to him as ‘the dean of fantasy writers’.”
