I tried to put into Uhura the qualities that I admire and demand of myself. Then I tried to develop the kind of person who would be entrusted with that kind of responsibility. She’s head of all communications on that ship, so she’s not just there pushing buttons. Those buttons are talking to people down in the bowels of the ship…For her or anyone to be entrusted with that kind of responsibility, I felt she had to have a strength and a dignity and a command of authority very much like Spock has.
