Doctor

fictional character from Star Trek: Voyager

The Doctor, an Emergency Medical Hologram Mark I (or EMH for short), is a fictional character from the television series Star Trek: Voyager, played by actor Robert Picardo. He is an artificial intelligence manifesting as a holographic projection, designed to act as a short-term supplement to the medical staff of a starship during emergency situations, but when the starship Voyager is stranded on the far side of the galaxy with no medical personnel, he is forced to act as the ship's chief medical officer for several years. In the style of the Star Trek franchise's exploration of artificial intelligence, a simple software program becomes a major character in the show, which aired on UPN between 1995 and 2001. In 2019, Picardo said CBS producers had expressed interest in having him appear in Star Trek: Picard, as either The Doctor or his creator, Lewis Zimmerman, whom Picardo also portrayed.
