Margot Lee Shetterly, a New York Times bestselling author, presents a captivating true story of four African-American female mathematicians at NASA, now tailored for young readers. These remarkable women, dubbed 'human computers', played a pivotal role in the space program before John Glenn's orbit and Neil Armstrong's moonwalk. Using simple tools like pencils, slide rules, and adding machines, they calculated the figures that propelled rockets and astronauts into space. The book vividly recounts the lives of Dorothy Vaughan, Mary Jackson, Katherine Johnson, and Christine Darden, who navigated the civil rights era, the Space Race, the Cold War, and the fight for gender equality, ultimately transforming NASA and the nation.
