What were NASA human computers, and what were they used for? And who were the women who worked as black computers in the famed West Computing Group?

In its earlier days, NASA (then NACA) employed an army of people, typically women, to work as NASA human computers. Amongst these people were the black computers who are the focus of the book Hidden Figures. Find out what they did, and how they changed NASA forever.

An Army of NASA Human Computers

During World War Two, the gradual dismantling of the Jim Crow system of racial segregation began, as the demands of the war economy brought African-Americans and women into jobs and industries from which they had previously been excluded. This was especially true of the aeronautics and defense industry, which was crucial to the American war effort. 

Facilities like Langley began to hire qualified women in large numbers to work as mathematicians and number-crunchers— NASA human computers. Aeronautics was an intensely quantitative field: designing and testing combat planes produced a deluge of numerical data that needed to be processed and analyzed. And that meant hiring an army of number-crunchers (“computers” as they were known at the time)

Women had been working as NASA human computers at Langley during the 1930s, but they would take on a far greater role at the laboratory during and after the war. By 1941, personnel officers at the lab were eagerly searching for more and more women (or “girls” as they were called at the time) to fill the new positions at Langley. Hiring agents scoured the East Coast for coeds who had any sort of mathematical background and placed job advertisements in newspapers in their endless quest for new talent.

West Area Computing and “Colored Computers”

Despite the opportunity, new arrivals to Langley like Dorothy still had to face the prejudice of living and working in a segregated city of the American South at the height of the Jim Crow era. Black people had to use separate bathrooms, separate drinking fountains, separate entrances on buses, send their children to separate schools, and live in separate neighborhoods—or face severe repercussions. Indeed, segregation was powerfully entrenched in the nation’s historical experience and was an all-encompassing feature of life in Virginia. This was true in the West Area Computing Group as well, and the NASA human computers experienced segregation.

The prejudice even followed these women into the laboratory at Langley. A separate area of the facility, known as West Area Computing, was reserved for the new black computers. Langley was generally a place where colleagues worked closely with one another. Because of the color of their skin, however, the West Computers were largely excluded from this collegial atmosphere. This was symbolized most hurtfully by the sign on the table where they sat at the back of the cafeteria that read, “COLORED COMPUTERS.” In an act of defiance, the women of West Computing began tearing the sign down each day they saw it, a first shot across the bow for equality and dignity.

Facing this climate of discrimination, the first generation of West Computers established their own culturally vibrant and cohesive communities all throughout Hampton Roads. Such communities enabled mobile young black families who’d moved to Virginia to keep their morale high and served to welcome and acclimate new waves of black migrants to the region. Eventually, the “Colored Computers” sign stayed down for good.

Additionally, as women began advancing through the ranks at Langley in the postwar years, they saw that their sex was still a barrier to advancement in a field that was built and run by men. There was a whole universe of networking, consisting of lunches, cocktail hours, and men-only smoking sessions from which the women were excluded. Moreover, the decentralized nature of their work also disadvantaged the female human computers. Because they were only given small portions of larger assignments to work on, it was difficult for the women to develop a holistic understanding of the kind of work the male engineers were doing.

The End of West Computing

By the mid-1950s, the National Advisory Committee for Aeronautics (NACA), the agency that housed Langley, was beginning to introduce mechanical computers into its laboratory spaces. Companies like Bell Telephone Laboratories and IBM were supplying the government with the first generation of mechanical data-processing machines. The female mathematicians’ jobs weren’t immediately placed in jeopardy, but the most astute among them, like Katherine, could certainly see the writing on the wall—that mastering these powerful machines would be essential to future success at Langley, and there would be less need for NASA human computers.

In addition to mastering the machines in the laboratory, Katherine and her peers would need to master another machine, one that dominated the social, economic, and political order of the South—the machine of Jim Crow. It would need to be smashed, defeated, and consigned to the ash heap of history if African-Americans were ever to advance and be seen as equals. This was all happening at a critical time for race relations in America.

The expanded mission and scope of NASA wrought major changes for the agency, transforming it into a high-profile bureaucracy with twice as many employees as it had before. It also signaled the end of an era for West Computing. Skill specialization was now the key to success at NASA: there was simply less of a need for a centralized pool like West Computing. Many of the original West Computers had already moved out of the pool, being assigned to mission-focused projects and divisions elsewhere at the laboratory. By the time NASA shuttered the West Computing Group in 1958, only nine remained, including Dorothy Vaughan. 

The Legacy of West Computing and the Human Computers

The end of the unit represented the end of an era, the disbanding of a band of sisters who had made great strides in smashing the color barrier in the United States. For the rest of their lives, the former West Computers would remember their experiences and tell their stories with the quiet dignity that was so characteristic of women of this generation. They didn’t see themselves as heroes—they were simply doing their jobs.

Their years at Langley would be marked by watershed moments in the fight for civil rights—the Brown v. Board of Education decision, the 1963 March on Washington for Jobs and Freedom, and the passage of the Civil Rights Act and the Voting Rights Act. As pioneers, the human computers had opened the doors for people of color who would follow in their footsteps. Mary Jackson always made a point of welcoming new black employees, helping them find places to live and offering them a home-cooked meal when they were homesick. 

The story of Katherine and her fellow NASA human computers of the West Computing Group is one of hope, of triumph over the harshest adversity. It is also one of empowerment—these women exercised real agency and control over the course of their lives. They were protagonists who acted upon America and shaped its destiny, protagonists in the great drama of the nation’s history. 

The NASA human computers made incredible contributions both to the war effort and to space exploration. From tearing down the “colored computers” sign to helping launch a man into space, the contributions of the black computers had a definitive effect on the world.

Carrie Cabral

Carrie has been reading and writing for as long as she can remember, and has always been open to reading anything put in front of her. She wrote her first short story at the age of six, about a lost dog who meets animal friends on his journey home. Surprisingly, it was never picked up by any major publishers, but did spark her passion for books. Carrie worked in book publishing for several years before getting an MFA in Creative Writing. She especially loves literary fiction, historical fiction, and social, cultural, and historical nonfiction that gets into the weeds of daily life.
