Hidden Figures Young Readers' Edition by Margot Lee ShetterlyFrom World War II through NASA's golden age, four African-American women confidently and courageously stepped into the National Advisory Committee for Aeronautics (now known as NASA). Their job? To provide the mathematical calculations that would help increase airplane production during wartime and eventually send the United States into space for the very first time. Hidden Figures follows the stories of Dorothy Vaughan, Mary Jackson, Katherine Johnson, and Christine Darden, who participated in some of the United States' greatest aeronautic successes.
