American horror writers

Harlan Jay Ellison (May 27, 1934 – June 28, 2018) was an American writer, known for his prolific and influential work in New Wave speculative fiction and for his outspoken, combative personality. His published works include more than 1,700 short stories, novellas, screenplays, comic book scripts, teleplays, essays, and a wide range of criticism covering literature, film, television, and print media. Some of his best-known works include the 1967 Star Trek episode "The City on the Edge of Forever", considered by some to be the single greatest episode of the Star Trek franchise (he subsequently wrote a book about the experience that includes his original teleplay), his A Boy and His Dog cycle (which was made into a film), and his short stories "I Have No Mouth, and I Must Scream" and "'Repent, Harlequin!' Said the Ticktockman". He was also editor and anthologist for Dangerous Visions (1967) and Again, Dangerous Visions (1972). Ellison won numerous awards, including multiple Hugos, Nebulas, and Edgars.
