The West Area Computing Unit was an all-Black group of female mathematicians who worked at the Langley Research Center of NACA.
NACA, NASA’s predecessor, recruited these women to work with computers during 1940s. Due to the Jim Crow laws of the time, these women were subject to using separate bathrooms and cafeterias and were originally under the charge of white supervisors. But in 1949, Dorothy Vaughan was put in charge, becoming NASA’s first black manager.
In 1958, when the NACA made the transition to NASA, their segregated facilities were abolished.
