Also Nurse Chapel, Lwaxanna Troi, and "computer"...
Majel Barrett Passed on today.
"Majel Barrett Roddenberry, the most ubiquitous actor in Star Trek, died today at age 76. The wife of Trek creator Gene Roddenberry, she also provided the computer voices on every version of Trek. And she played three pivotal characters: Number One in the pilot, Nurse Chapel in the original series, and Lwaxana Troi in TNG and DS9. She was providing the computer voices for the new Trek movie, and it's not clear if she had finished recording them."
