August William Derleth was born in Sauk City, Wisconsin, in 1909. In addition to his association with Lovecraft, both as a publisher and a “collaborator,” he was a prolific writer in his own right. He wrote genre fiction including Gothic and horror stories, pastiches of Sherlock Holmes stories, and historical, regional novels including the Sac Prairie Saga, which is a collection of novels, novellas, and short stories, based on Sauk City, describing the everyday life of a small farming community in Wisconsin.
