The Doctor (Star Trek)
fictional character from Star Trek: Voyager
The Doctor, an Emergency Medical Hologram (EMH), is a fictional character portrayed by actor Robert Picardo in the television series Star Trek: Voyager, Star Trek: Prodigy, and Star Trek: Starfleet Academy. He is an artificial intelligence manifesting as a holographic projection, and designed to be a short-term adjunct to medical staff in emergency situations. However, when the USS Voyager is stranded on the far side of the Milky Way galaxy without medical personnel, he is forced to act as the starship's permanent chief medical officer. In an example of the Star Trek franchise's exploration of artificial intelligence, a rudimentary algorithm becomes a major character in the show.
Casting
In a 2020 interview, Picardo said his agent told him that he was selected from 900 actors who auditioned for the role.
"I got the part without understanding that the character would be the outsider, the Spock-like character. The character who initially inherited that was Data, who had no emotion and longed to be a real boy in the same way as Pinocchio. I thought that, because Tuvok was a Vulcan character, he would deal with those issues. Once I realized that I had gotten the plum role, it was a delightful surprise. I went from thinking I had the dullest role in the show to believing I may have the best role in the show.
