Majel Barrett-Roddenberry (23 February 1932 – 18 December 2008

"Roddenberry was involved in the "Star Trek" universe for more than four decades. She played the dark-haired Number One in the original pilot but metamorphosed into the blond, miniskirted Nurse Christine Chapel in the original 1966-69 show. She had smaller roles in all five of its television successors and many of the "Star Trek" movie incarnations, although she had little involvement in the productions."
