Howard Phillips (H.P.) Lovecraft (1890-1937) was an influential author best known for his science fiction, horror and fantasy stories, and among those stories his best known ones are those that combine elements of all three. Through that mixture, Lovecraft became the most celebrated author of a genre known as “weird fiction”, especially with his works on the the monster Cthulhu , which has continued to be the subject of other writers’ works. Today, an entire mythos centers around Cthulhu, bringing together all of the different stories from all of the different writers.
