TOS 16 The Menagerie Part 2
This was, of course, Majel Barrett’s actual name, Majel Leigh Hudec, playing the part of the first officer Number 1. Since this was the pilot for the series, the network told Roddenberry that having a woman in command was unbelievable, and they asked him to take her out and, while he was at it, get rid of the guy with the pointed ears. He saved one of the two (and married the other).
