Four black women, Engineers Christine Darden and Mary Jackson, mathematician Katherine Johnson, and computer programmer Dorothy Vaughan, worked as "human computers" at NASA during the Space Race, making space travel possible through their complex calculations. Jackson, Johnson, and Vaughn all played a vital role in helping John Glenn become the first American to orbit the Earth.
They worked behind the scenes, but now they're getting the credit they deserve as their accomplishments are brought to the forefront. Their amazing stories were detailed in the book "Hidden Figures: The American Dream and the Untold Story of the Black Women Mathematicians Who Helped Win the Space Race" by Margot Lee Shetterly, which was later turned into a movie. (Darden was not featured in the movie, but was in the book). Johnson has a building at NASA named after her, and a street in front of NASA's Washington D.C. headquarters was renamed "Hidden Figures Way."
