Sad to hear this, really liked the way she played the character.
While I didn't meet her personally, she was the featured guest at a Star Trek convention I attended in Dallas in 1989. She told a story about meeting Whoopi Goldberg a few months earlier while Goldberg was shooting scenes from a Next Generation episode while Nichols was shooting scenes from Star Trek 5 on adjacent lots at Paramount. Each of them idolized the other, Nichols told us.
She was, very quietly, a groundbreaking and classy actress.
RIP Nichelle Nichols
