Hidden Figures: The Untold Story of the Black Women Mathematicians Who Powered Early Space Exploration

A heartening testament to “the triumph of meritocracy” and to the idea that “each of us should be allowed to rise as far as our talent and hard work can take us.”

Hidden Figures: The Untold Story of the Black Women Mathematicians Who Powered Early Space Exploration

“No woman should say, ‘I am but a woman!’ But a woman! What more can you ask to be?” astronomer Maria Mitchell, who paved the way for women in American science, admonished the first class of female astronomers at Vassar in 1876. By the middle of the next century, a team of unheralded women scientists and engineers were powering space exploration at NASA’s Jet Propulsion Laboratory.

Meanwhile, across the continent and in what was practically another country, a parallel but very different revolution was taking place: In the segregated South, a growing number of black female mathematicians, scientists, and engineers were steering early space exploration and helping American win the Cold War at NASA’s Langley Research Center in Hampton, Virginia.

Long before the term “computer” came to signify the machine that dictates our lives, these remarkable women were working as human “computers” — highly skilled professional reckoners, who thought mathematically and computationally for their living and for their country. When Neil Armstrong set his foot on the moon, his “giant leap for mankind” had been powered by womankind, particularly by Katherine Johnson — the “computer” who calculated Apollo 11’s launch windows and who was awarded the Presidential Medal of Freedom by President Obama at age 97 in 2015, three years after the accolade was conferred upon John Glenn, the astronaut whose flight trajectory Johnson had made possible.

In Hidden Figures: The Story of the African-American Women Who Helped Win the Space Race (public library), Margot Lee Shetterly tells the untold story of these brilliant women, once on the frontlines of our cultural leaps and since sidelined by the selective collective memory we call history.

She writes:

Just as islands — isolated places with unique, rich biodiversity — have relevance for the ecosystems everywhere, so does studying seemingly isolated or overlooked people and events from the past turn up unexpected connections and insights to modern life.

Against a sobering cultural backdrop, Shetterly captures the enormous cognitive dissonance the very notion of these black female mathematicians evokes:

Before a computer became an inanimate object, and before Mission Control landed in Houston; before Sputnik changed the course of history, and before the NACA became NASA; before the Supreme Court case Brown v. Board of Education of Topeka established that separate was in fact not equal, and before the poetry of Martin Luther King Jr.’s “I Have a Dream” speech rang out over the steps of the Lincoln Memorial, Langley’s West Computers were helping America dominate aeronautics, space research, and computer technology, carving out a place for themselves as female mathematicians who were also black, black mathematicians who were also female.

Shetterly herself grew up in Hampton, which dubbed itself “Spacetown USA,” amid this archipelago of women who were her neighbors and teachers. Her father, who had built his first rocket in his early teens after seeing the Sputnik launch, was one of Langley’s African American scientists in an era when words we now shudder to hear were used instead of “African American.” Like him, the first five black women who joined Langley’s research staff in 1943 entered a segregated NASA — even though, as Shetterly points out, the space agency was among the most inclusive workplaces in the country, with more than fourfold the percentage of black scientists and engineers than the national average.

Over the next forty years, the number of these trailblazing black women mushroomed to more than fifty, revealing the mycelia of a significant groundswell. Shetterly’s favorite Sunday school teacher had been one of the early computers — a retired NASA mathematician named Kathleen Land. And so Shetterly, who considers herself “as much a product of NASA as the Moon landing,” grew up believing that black women simply belonged in science and space exploration as a matter of course — after all, they populated her father’s workplace and her town, a town whose church “abounded with mathematicians.”

Embodying astronomer Vera Rubin’s wisdom on how modeling expands children’s scope of possibility, Shetterly reflects on this normalizing and rousing power of example:

Building 1236, my father’s daily destination, contained a byzantine complex of government-gray cubicles, perfumed with the grown-up smells of coffee and stale cigarette smoke. His engineering colleagues with their rumpled style and distracted manner seemed like exotic birds in a sanctuary. They gave us kids stacks of discarded 11×14 continuous-form computer paper, printed on one side with cryptic arrays of numbers, the blank side a canvas for crayon masterpieces. Women occupied many of the cubicles; they answered phones and sat in front of typewriters, but they also made hieroglyphic marks on transparent slides and conferred with my father and other men in the office on the stacks of documents that littered their desks. That so many of them were African American, many of them my grandmother’s age, struck me as simply a part of the natural order of things: growing up in Hampton, the face of science was brown like mine.


The community certainly included black English professors, like my mother, as well as black doctors and dentists, black mechanics, janitors, and contractors, black cobblers, wedding planners, real estate agents, and undertakers, several black lawyers, and a handful of black Mary Kay salespeople. As a child, however, I knew so many African Americans working in science, math, and engineering that I thought that’s just what black folks did.

But despite the opportunities at NASA, almost countercultural in their contrast to the norms of the time, life for these courageous and brilliant women was no idyll — persons and polities are invariably products of their time and place. Shetterly captures the sundering paradoxes of the early computers’ experience:

I interviewed Mrs. Land about the early days of Langley’s computing pool, when part of her job responsibility was knowing which bathroom was marked for “colored” employees. And less than a week later I was sitting on the couch in Katherine Johnson’s living room, under a framed American flag that had been to the Moon, listening to a ninety-three-year-old with a memory sharper than mine recall segregated buses, years of teaching and raising a family, and working out the trajectory for John Glenn’s spaceflight. I listened to Christine Darden’s stories of long years spent as a data analyst, waiting for the chance to prove herself as an engineer. Even as a professional in an integrated world, I had been the only black woman in enough drawing rooms and boardrooms to have an inkling of the chutzpah it took for an African American woman in a segregated southern workplace to tell her bosses she was sure her calculations would put a man on the Moon.


And while the black women are the most hidden of the mathematicians who worked at the NACA, the National Advisory Committee for Aeronautics, and later at NASA, they were not sitting alone in the shadows: the white women who made up the majority of Langley’s computing workforce over the years have hardly been recognized for their contributions to the agency’s long-term success. Virginia Biggins worked the Langley beat for the Daily Press newspaper, covering the space program starting in 1958. “Everyone said, ‘This is a scientist, this is an engineer,’ and it was always a man,” she said in a 1990 panel on Langley’s human computers. She never got to meet any of the women. “I just assumed they were all secretaries,” she said.

These women’s often impossible dual task of preserving their own sanity and dignity while pushing culture forward is perhaps best captured in the words of African American NASA mathematician Dorothy Vaughan:

What I changed, I could; what I couldn’t, I endured.

In the remainder of her beautifully written, rigorously researched, and culturally sobering book, Shetterly goes on to explore the lives of a number of the early computers: how they became who they are and what difficult choices they often had to make between their personal and professional lives — choices many of which remain just as impossible and unjust for women today.

But the particular fate of these pioneering women offers something singularly emboldening.

Shetterly reflects on the gasp of a reaction she most often faces when people first hear the story: the disorientation and discomfiting surprise of realizing they’ve been unaware that black women mathematicians not only worked at NASA but were instrumental to the feats of space exploration — feats that brought humanity together around a shared sense of pride, but a pride for which its very achievers were given no credit. She writes:

Most people are astonished that a history with such breadth and depth, involving so many women and linked directly to the twentieth century’s defining moments, has flown below the radar for so long. There’s something about this story that seems to resonate with people of all races, ethnicities, genders, ages, and backgrounds. It’s a story of hope, that even among some of our country’s harshest realities — legalized segregation, racial discrimination — there is evidence of the triumph of meritocracy, that each of us should be allowed to rise as far as our talent and hard work can take us.

Complement the wonderful and important Hidden Figures with the untold story of the women soldiers who dressed and fought as men in the Civil War and this illustrated celebration of trailblazing women in science, then revisit the story of “the rocket girls” — the Hampton computers’ West Coast counterparts.
