Hidden Figures: The American Dream and the Untold Story of the Black Women Who Helped Win the Space Race is a 2016 nonfiction book written by Margot Lee Shetterly. Shetterly started working on the book in 2010. The book takes place from the 1930s through the 1960s when some viewed women as inferior to men. The biographical text follows the lives of Katherine Johnson, Dorothy Vaughan, and Mary Jackson, three mathematicians who worked as computers (then a job description) at NASA, during the space race. They overcame discrimination there, as women and as African Americans. Also featured is Christine Darden, who was the first African-American woman to be promoted into the Senior Executive Service for her work in researching supersonic flight and sonic booms.
