Jerome Bixby (1923–1998) was an American short-story writer and screenwriter. His 1953 story It's a Good Life became a celebrated Twilight Zone episode, and he co-wrote the story for the film Fantastic Voyage and later wrote The Man from Earth.
Bixby wrote four Star Trek episodes: Mirror, Mirror, which created the Mirror Universe and its brutal Terran Empire; By Any Other Name, co-written with D.C. Fontana; Day of the Dove; and Requiem for Methuselah. The Deep Space Nine Mirror Universe episode The Emperor's New Cloak was dedicated to his memory.
