Robert Albert Bloch (; April 5, 1917 – September 23, 1994) was an American fiction writer, primarily of crime, psychological horror, and fantasy, much of which has been dramatized for radio, cinema and television. He also wrote a relatively small amount of science fiction. His writing career lasted 60 years, including more than 30 years in television and film. He began his professional writing career immediately after graduation from high school, aged 17. He is best known as the writer of the novel Psycho (1959), the basis for the 1960 film Psycho directed by Alfred Hitchcock. Bloch wrote hundreds of short stories and over 30 novels. He was a protégé of H. P. Lovecraft, who was the first to seriously encourage his talent. However, while he started emulating Lovecraft and his brand of cosmic horror, he later specialized in crime and horror stories, often emphasizing psychological aspects of the characters within. 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. He won the Hugo Award (for his story "That Hell-Bound Train"), the Bram Stoker Award, and the World Fantasy Award. He served a term as president of the Mystery Writers of America (1970) and was a member of that organization and of Science Fiction Writers of America, the Writers Guild of America, the Academy of Motion Picture Arts and Sciences and the Count Dracula Society. In 2008, The Library of America selected Bloch's essay "The Shambles of Ed Gein" (1962) for inclusion in its two-century retrospective of American true crime. His favorites among his own novels were The Kidnapper, The Star Stalker, Psycho, Night-World, and Strange Eons. His work has been extensively adapted into films, television productions, comics, and audiobooks.
