Majel Barrett

Often known as "The First Lady of Star Trek," Majel Barrett took acting classes as a child and as a young woman she worked on several shows at the Desilu studios. They included the long-running pioneer series "Bonanza," the Prohibition-era crime drama "The Untouchables," and the screwball "The Lucy Show." Barrett appeared in the pilot episode of "Star Trek" in 1964, and she became romantically involved with its creator, Gene Roddenberry, and later married him.

Her character was changed from "Number One," a first officer on board the Starship Enterprise, to Nurse Christine Chapel -- a woman who had a crush on Leonard Nimoy's Spock. In the 1979 film "Star Trek: The Motion Picture," we are informed that Chapel has become a doctor, and this character is also briefly seen in "Star Trek IV: The Voyage Home." Otherwise, Barrett kept busy on most of the incarnations of the show as the voice of onboard "Star Trek" computers.
