Dorothy Vaughan was a math teacher in Farmville, Virginia and joined the Langley Memorial Aeronautical Laboratory part-time in 1943. An abundance of data led to Vaughan obtaining a full-time job at the laboratory.
Separated from other white supervisors, Vaughan went on to become the first black supervisor at NACA and ensured that all employees were getting the recognition they deserved in the form of raises and promotions. After NACA became NASA, internal segregation was banned, and she worked among her other supervisors.
Dorothy Vaughan was also an expert programmer and assisted in SCOUT, a satellite-launching rocket. She retired in 1971 from her job at NASA.
