Explores the previously uncelebrated but pivotal contributions of NASA's African American women mathematicians to America's space program, describing how Jim Crow laws segregated them despite their groundbreaking successes. Includes biographies on Dorothy Jackson Vaughan (1910-2008), Mary Winston Jackson (1921-2005), Katherine Colman Goble Johnson (1918- ), Dr. Christine Mann Darden (1942- ).
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. New York Times bestselling author Margot Lee Shetterly and illustrator Laura Freeman bring to life the inspiring story of the struggles of these four "hidden figures" and what they overcame to succeed. The math work they did would change not only their own lives, but the face of air and space travel forever. -- From dust jacket.
