In Hidden Figures, Margot Lee Shetterly reveals the real-life stories of Katherine Johnson, Dorothy Vaughan, Mary Jackson, and Christine Darden — the black women of NASA who braved the insurmountable and conquered the impossible. Even with Virginia's Jim Crow imposing segregation laws, these four African-American women defied the odds against both racial discrimination and gender bias. They were among Langley's all-black "West Computing", a group of women who proved invaluable in the pursuit of both the triumph over the Soviet Union and America's dominion on the race to the heavens. Behind John Glenn's orbital flight and Neil Armstrong's iconic moonwalk were these exceptional "human computers". Armed with slide rules, papers, and pencils, they created satellite, rocket, and airplane designs and helped guarantee the nation's victory in World War II, the Cold War, the Civil Rights Movement, and the Space Race.
