John Collier (1901-1980) was born in London. He began his writing career as a poet, first publishing in 1920. He turned to fiction in the early 1930s, producing the popular and controversial novel, His Monkey Wife, about a man who is married to a chimpanzee. In 1935 Collier left England for Hollywood, where he became an active and prolific writer for film and later television; he was particularly influential in developing the brilliantly creepy and subversive style of such television classics as “Alfred Hitchcock Presents” and “The Twilight Zone.” An adaptation from Milton, Paradise Lost: Screenplay for Cinema of the Mind was published in 1973, but never produced as a film. Collier’s other works range from the poetry collection Gemini (1931) to the novels Tom’s A-Cold(1933) and Defy the Foul Fiend (1934), and the short story collections Presenting Moonshine (1941), Fancies and Goodnights (1951), Pictures in the Fire (1958), The John Collier Reader (1972), and The Best of John Collier (1975).

Ray Bradbury started writing fiction at the age of twelve and published his first story when he was twenty. He has since written more than thirty books—novels, stories, essays, plays, and poems—including The Martian Chronicles (1950), the futuristic novel Fahrenheit 451 (1952), and a collection of short stories The Illustrated Man (1951). He lives with his wife in Los Angeles.
