Lyon Sprague de Camp was born in 1907 and died in 2000. During a writing career that spanned seven decades, he wrote over a hundred books in the areas of science fiction, fantasy, historical fiction, non-fiction and biography. Although arguably best known for his continuation of Robert E. Howard's Conan stories, de Camp was an important figure in the formative period of modern SF, alongside the likes of Isaac Asimov and Robert A. Heinlein, and was a winner of the HUGO, WORLD FANTASY LIFE ACHIEVEMENT and SFWA GRAND MASTER AWARDs.
