Yes she does.
In the US at the time of the story she would have been identified as black by both the black and white cultures of the time.
She has some white features but she would be seen as black by all.
I don’t get it. We’ve got some people here saying she wasn’t all that smart, didn’t contribute all that much, a glorified secretary or a low level data entry number crunching clerk and then others who say she was brilliant but only because she wasn’t all that black and or “passed” for white.
