Abstract:Katherine, Dorothy, Mary, and Christine were all good at math. Really good. And it was their understanding of numbers that helped them do what seemed impossible. They were women, and they were African-American, and they lived during a time when being black and a woman limited what they could do. But Katherine, Dorothy, Mary, and Christine were hardworking and persistent and, most important, smart. And that's why NASA hired them to do the math that would one day send the United States into space for the very first time. -- From dust jacket.
