Throughout World War II and the Space Race of the 1950s and ’60s, mechanical calculators and slide rules aided “human computers” whose calculations contributed to groundbreaking projects. NASA’s Langley Research Center employed hundreds of female computers from the mid-1930s to the ’70s. During the 1940s, Langley began recruiting African American women, such as Dorothy Vaughan (1910–2008), a former math teacher, who joined the “West Area Computing” unit, an all-Black group of female mathematicians, in 1943.
