Robert Bloch (1917-1994) was a prolific American writer, primarily of crime, horror and science fiction. He is best known as the writer of Psycho, the basis for the film of the same name by Alfred Hitchcock. He was also known as an excellent standup speaker with a wry sense of humor. Bloch wrote hundreds of short stories and over twenty novels, usually crime fiction, science fiction and, perhaps most influentially, horror fiction. He was one of the youngest members of the Lovecraft Circle. Bloch was a contributor to pulp magazines such as Weird Tales in his early career, and was also a prolific screenwriter and a major contributor to science fiction fanzines and fandom in general.
