Drexel Jerome Lewis Bixby (January 11, 1923 in Los Angeles – April 28, 1998 in San Bernardino, California) was an American short story writer, editor and scriptwriter, best known for his work in science fiction. He also wrote many westerns and used the pseudonyms Jay Lewis Bixby, D. B. Lewis, Harry Neal, Albert Russell, J. Russell, M. St. Vivant, Thornecliff Herrick and Alger Rome (for one collaboration with Algis Budrys). He is most famous for the 1953 story "It's a Good Life" which was the basis for a 1961 episode of The Twilight Zone and which was included in Twilight Zone: The Movie (1983). He also wrote four episodes for the Star Trek series: "Mirror, Mirror", "Day of the Dove", "Requiem for Methuselah", and "By Any Other Name". With Otto Klement, he co-wrote the story upon which the classic sci-fi movie Fantastic Voyage (1966), television series, and novel by Isaac Asimov were based (as well the third episode of the The Magic Schoolbus, 'Inside Relphie'). Bixby's final work was the screenplay for the 2007 cult sci-fi film The Man From Earth.
