Melvin Butler himself hailed from Portsmouth, just across the bay from Hampton. It required no imagination on his part to guess what some of his fellow Virginians might think of the idea of integrating Negro women into Langley’s offices, the “come-heres” (as the Virginians called the newcomers to the state) and their strange ways be damned. There had always been Negro employees in the lab—janitors, cafeteria workers, mechanic’s assistants, groundskeepers. But opening the door to Negroes who would be professional peers, that was something new.
State law—and Virginia custom—kept him from truly progressive action, but perhaps the promise of a segregated office was just the cover he needed to get the black women in the door, a Trojan horse of segregation opening the door to integration. Whatever his personal feelings on race, one thing was clear: Butler was a Langley man through and through, loyal to the laboratory, to its mission, to its worldview, and to its charge during the war. By nature—and by mandate—he and the rest of the NACA were all about practical solutions.
My dad joined Langley in 1964 as a coop student and retired in 2004 an internationally respected climate scientist. Five of my father’s seven siblings made their bones as engineers or technologists, and some of his best buddies—David Woods, Elijah Kent, Weldon Staton—carved out successful engineering careers at Langley. Our next-door neighbor taught physics at Hampton University. Our church abounded with mathematicians. Supersonics experts held leadership positions in my mother’s sorority, and electrical engineers sat on the board of my parents’ college alumni associations.
