… Vaughan was assigned to the segregated “West Area Computing” unit, an all-black group of female mathematicians, who were originally required to use separate dining and bathroom facilities. Over time, both individually and as a group, the West Computers distinguished themselves with contributions to virtually every area of research at Langley.
The group’s original section heads (first Margery Hannah, then Blanche Sponsler) were white. In 1949, Dorothy Vaughan was promoted to lead the group, making her the NACA’s first black supervisor, and one of the NACA’s few female supervisors (see also Virginia Tucker). The Section Head title gave Dorothy rare center wide visibility, and she collaborated with other well-known computers like Vera Huckel and Sara Bullock on projects such as compiling a handbook for algebraic methods for calculating machines. Vaughan was a steadfast advocate for the women of West Computing, and even intervened on behalf of white computers in other groups who deserved promotions or pay raises. Engineers valued her recommendations as to the best “girls” for a particular project, and for challenging assignments they often requested that she personally handle the work.
In 1958, when the NACA made the transition to NASA, segregated facilities, including the West Computing office, were abolished. Dorothy Vaughan and many of the former West Computers joined the new Analysis and Computation Division (ACD), a racially and gender-integrated group on the frontier of electronic computing. Dorothy Vaughan became an expert FORTRAN programmer, and she also contributed to the Scout Launch Vehicle Program. Scout, an acronym for Solid Controlled Orbital Utility Test system, is a four-stage solid fuel satellite system capable of launching a 385-pound satellite into a 500-mile orbit. There have been 118 Scout launches, and its overall 96 percent success rate has earned a spot in the National Air and Space Museum.
Dorothy Vaughan retired from NASA in 1971. She sought, but never received, another management position at Langley. Her legacy lives on in the successful careers of notable West Computing alumni, including Mary Jackson, Katherine Johnson, Eunice Smith and Kathryn Peddrew, and the achievements of second-generation mathematicians and engineers such as Christine Darden.
