What Did the People in Hidden Figures Do?

I think my issue with 'hidden figures' is that it's portrayed that it's somehow racist that they got no recognition for their part in the space program.

Most employees at large organizations that are essentially low-level programmers/developers don't get the public recognition for completed projects/products, regardless of skin color.

Do you know the names of the engineers at Tesla? Or do we give all the credit to Elon Musk?
