The Hidden Figures of NASA: Black Women Mathematicians and the Space Race

Hidden Figures reveals a truer picture: that black women “are part of the American epic” that placed astronauts on the moon. And it’s long past time we celebrated their efforts.

Hidden Figures tells the story of the women who performed the behind-the-scenes work that propelled American aviation triumphs during World War II and Space Age rocketeering. Author Margot Lee Shetterly focuses on a particular group of pioneering women working at NACA/NASA,[*] the African-American women who overcame barriers imposed by both their gender and their race. Called computers, they were mathematicians whose work entailed calculating complex equations for the engineers engaged in the then emerging field of aeronautics.

The Call to Serve

The first female computing pool, then all white, formed due to necessity. Prior to 1935, the male (usually white) engineers performed their own calculations, a tedious task that slowed their research. Historian Beverly E. Golemba notes that “Because of the male shortage and the added attractiveness of paying women less, they rather reluctantly began to hire women as computers.” Despite their qualms, these white women soon proved themselves equal—and better—at the task. Although they earned less than male counterparts despite possessing equivalent bachelor degrees,[†] NACA still paid better than teaching did and permitted them to continue working long after marriage and the arrival of children.

The demand for human computers soon outstripped the supply of qualified white women available. President Franklin D. Roosevelt, pressured by black labor union leader A. Philip Randolph’s threat to march on Washington, signed an executive order that desegregated the defense industry and made it possible for black women to become computers. Although advertisements for black computers were more discreet during this segregated era, they nonetheless attracted the attention of Dorothy Vaughn (the first black female supervisor) in 1943,[‡] one of the three computers Shetterly’s book features. Cold War concerns kept NACA’s Langley Research Center (located in Hampton, Virginia) retaining and continuing to hire more computers to process the vast data produced by the research conducted there.

The Friden calculator was one of machines that human computers once used to perform complex calculations.

Calculating Times of Change

As Shetterly follows Dorothy Vaughn, Mary Jackson, and Katherine G. Johnson (famed for calculating flight trajectories of the Mercury and Apollo space missions) through the highlights of their careers into the late 1960s, she also performs the daunting task of capturing a cross-section of the eras in which these women worked. Moving from World War II to the Cold War and Space Race accompanied by the burgeoning Civil Rights movement, she laces her narrative with layperson discussions of aeronautical innovations. Shetterly, too, describes the complex calculations (Johnson’s figures are compared to a symphony) while underscoring the human cost of miscalculations: loss of life. At times, one wishes for more biographical and less technical detail, but the perspective is critical for understanding her subject’s work. Shetterly correctly observes that it’s important to learn about the computers who worked at NACA/NASA and document their work—all while recording the obstacles these black women overcame.

Among the book’s poignant moments, Shetterly recounts Katherine Johnson’s[§] journey to Langley from West Virginia in 1953. Once her bus entered Virginia, she entered a segregated state; she and other black passengers were required to move to the bus’s back. Later, they all had to disembark as the bus would not travel through the black part of town. Johnson ignored segregation and gender-based discrimination when she could, unafraid to use a white only bathroom or ask why she, a female computer, could not attend the Space Task Force editorial meetings with the male engineers.

Mary Jackson, a Virginia native and Hampton local hired in 1951, discussed her frustration with unequal work conditions to an engineer who responded with an invitation to join his team; this move launched her career as the first female black engineer. To attain that rank, however, she needed special permission to go to classes at the segregated local high school she’d unable to attend as a teen. The school, which she expected to be superior to the one she matriculated from, was dilapidated: the full cost of segregated school systems was fewer and worse resources for all.

“What I changed, I could; what I couldn’t, I endured” were Dorothy Vaughn’s words to Golemba about her time at Langley. Disappointed that she did not again attain a management position after NASA integrated its staff in 1958, she launched many careers during her time as a supervisor (Katherine Johnson’s included).[**] Vaughn soon observed that computing machines would gain ascendancy, and she made it imperative that she and other human computers learn how to code them, thus making themselves indispensable to NASA. And it would be Johnson’s calculations that would confirm the accuracy of the new machines, giving NASA (not to mention astronaut John Glenn) confidence in the machine’s calculations.

Finally, Zeroing on Hidden Figures

When reading about these women’s accomplishments and considering how often the Space Race has been memorialized, it seems shocking that we didn’t know these women’s names earlier. Of the many computers named in Hidden Figures (both black and white), I only knew of Katherine Johnson beforehand. Shetterly acknowledges, as other authors do, the role that the women’s modesty played. She also adds that many people did know about the work these women undertook (particularly in Hampton, which happens to be the author’s hometown). Yet, this knowledge remained unseen by the public. As Shetterly indicated in an interview on NPR’s All Things Considered, “…I think that it really does have to do with us…not valuing that work that was done by women, however necessary, as much as we might. And it has taken history to get a perspective on that.”

Shetterly’s remarks here are hardly controversial: women’s work (particularly domestic) long has been undervalued and unappreciated. Writing Hidden Figures: The American Dream and the Untold Story of the Black Women Mathematicians Who Helped Win the Space Race provides this much needed corrective accounting. Both black and white computers’ contributions alike were forgotten while white men they worked alongside were lauded. As reporter Virginia Biggins explained during a panel that discussed the role of human computers, she “just assumed they were all secretaries”. Hidden Figures reveals a truer picture: that black women “are part of the American epic” that placed astronauts on the moon. And it’s long past time we celebrated their efforts.

[†] Golemba’s unpublished report indicated most computers pursued mathematical degrees because it was a subject at which they excelled in high school and that most intended to use the degree as part of a teaching career.

[‡] Shetterly discusses other black computers and their careers where appropriate but the book’s scope does not permit spending much time with them. However, her ongoing project, The Human Computer project, strives to capture the history of the women who served as computers.

[§] Katherine Johnson was then Katherine Goble, as her first husband was still alive.

[**] Although Shetterly focuses mostly on black women, she also exposes the gender-based struggles white women encountered where appropriate. When Dorothy Vaughn intervened on Katherine Johnson’s behalf and helped her obtain a permanent position (and promotion) to a team where she’d been temporarily assigned, Vaughn also helped a white computer gain the same appointment. Not having anyone to forward her cause, her request to join the team would otherwise been ignored.

Science Asides: Ethics in The Immortal Life of Henrietta Lacks

Recently, I chanced upon an Atlas Obscura article discussing lördagsgodis, the Swedish tradition of indulging in candy on Saturdays. What drew my attention, however, was that title mentioned “human experimentation”. As it happens, lördagsgodis’s roots can be traced to experiments performed on mentally ill patients during the mid- to late 1940s that established sugar’s role in cavity formation. The study, which neither benefited its patients (quite the opposite) nor obtained their consent, was not unique to Sweden.[*] In fact, its ethical issues suggested those raised in The Immortal Life of Henrietta Lacks, the tale of an African-American woman whose cells, collected without her permission in 1951, led to profound scientific discoveries. Given how deeply this nonfictional account delves into medical ethics, politics, racism, and scientific discovery as they intertwine with the lives of Henrietta Lacks and her family, I will focus on the more poignant moments that exemplify these issues.

History, Ethics, and Human Experimentation

As author Rebecca Skloot observes, patients of US public wards often were unaware that they served as research subjects, something some researchers considered to be an acceptable trade for receiving treatment (29–30). Such patients, particularly impoverished, poorly educated African-American patients living in the pre—Civil Rights era in the United States were unlikely to ask questions: the presumption that physicians “knew best” coupled with widespread racism alone prevented such a thing (Skloot 63). And before the advent of Institutional Review Boards in 1966 (Sparks 2017),[†] research involving human participants did not receive much formal oversight (Skloot 131, 136). What happened to Henrietta Lacks, specifically taking her cancer cells without her knowledge or consent, was both the norm however unpalatable we might find it.

For Henrietta, there were more personal consequences related to the treatment that permitted her cells to be collected. Johns Hopkins, the hospital where Henrietta was treated, standardly informed women of childbearing years that hysterectomy led to infertility—one of the rare instances where patients did receive adequate information from physicians in this book. And yet this did not happen in Henrietta’s case. Her records revealed that she would have refused treatment had she known (Skloot 47–8). And although she would not have lived long enough to bear another child (Skloot 86), the choice should have been hers. The tissue sample collected from this hysterectomy, however, continued to grow long past its expected life: the discovery of an immortal line of human cells had been found (Skloot 40–1).

Amazing Discoveries and Uncomfortable Juxtapositions

The importance of Henrietta’s cells (called HeLa) to scientific research is vast. For example, HeLa played a large role in proving that Salk’s polio vaccine worked—and it was African-American scientists and technicians who produced the massive quantities of HeLa cells needed to do so (Skloot 93–7). Yet this achievement also represents one of the most painful juxtapositions in The Immortal Life: the HeLa factory was located at The Tuskegee Institute, a place better known for its infamous syphilis study involving African-American men.[‡] The terrible disparity between HeLa’s role in saving the lives of so many people—regardless of their racial background—and the unnecessary deaths of African-American people is more shocking when you consider that twelve of the Tuskegee study participant’s children still receive benefits (CDC 2017).

Disclosure and Family Distress

Not long after Henrietta was identified as the HeLa “donor” in the early 1970s, the Lacks family discovered that her cells were still alive, a revelation they did not understand and found alarming (Skloot 173, 175–81). Further interactions with researchers did little to improve their understanding. When researchers obtained blood samples from Henrietta’s family to establish genetic markers for HeLa, the Lacks family thought they were being tested for cancer (Skloot 180–4). More alarmingly, the resulting study published Henrietta’s name with her genetic information (Skloot 197–8). And more medical information was revealed about Henrietta without consulting the Lacks family. In the 1980s, her medical records were published, something which caused immense grief for Henrietta’s daughter, as Deborah read intimate details about her mother’s diagnosis and the anguish she suffered before her death (Skloot 209–10). Other family members, however, were angered by the profits made by biomedical companies while their family remained impoverished and could not afford health insurance (Skloot 168, 193).

Thoughtfulness and Modern Ethics

And this is perhaps the most concerning theme that The Immortal Life of Henrietta Lacks reveals: thoughtlessness. Mary Kubicek was an assistant who was sent to collect tissue samples during Henrietta’s autopsy in 1951. Unaccustomed to dealing with dead bodies, she focused her gaze away from Henrietta’s eyes. Then, she noticed Henrietta’s painted toenails and realized that Henrietta was an actual person, not just a collection of cells. It was something she had not considered before. It’s astonishing how many researchers (most but not all of whom were white) echoed this refrain and never thought about whether patients and/or their families might have concerns, even after ethical standards were changed. And this best represents what was most needed here, for researchers to think of Henrietta Lacks as a human with rights instead of as HeLa’s source. To think of all patients involved in research as people first.

* * *

Originally, I intended to end where the book does, with the emphasis on the need to see patients as people instead of mere study subjects. Instead, I discovered something of an unpleasant (if unsurprising) postscript: the Lacks family again needed to protest the public distribution of information about Henrietta. In 2013, the European Molecular Biology Laboratory published the genome of a line of HeLa cells to an online database that allowed public downloads of this data. Although no laws were broken (Callaway 2013), it seems the researchers did not consider the ethical implications of making genetic data  publicly available that could be potentially reveal private information about Henrietta’s family (Skloot 2013). The database subsequently was removed and the National Institutes of Health, who also planned to publish a similar paper, established a review board (that includes two of Henrietta’s family members) to determine who will gain access to this genetic information in the future (Zimmer 2013). While this hopefully will provide Henrietta’s family with much needed closure on this topic, questions remain about how geneticists should handle such sensitive data for other patients.

[*] Elsie Lacks, Henrietta’s daughter, resided at a facility for mentally ill patients where medical experiments were carried out on the African-American patients living there, again without consent. She likely was a study subject. She died in 1955 (Skloot 274–6).

[†] HeLa also played a role in the formation of these boards. The discovery that researcher Chester Southam had been injecting HeLa cells into patients (roughly half of whom were diagnosed with cancer) without disclosure and consent caused a scandal that prompted the National Institutes of Health to create these boards (Skloot 127–36).

[‡] This study’s notoriety primarily stems from (but is not limited to) the fact that researchers purposefully withheld treatment from patients afflicted with syphilis long after a cure was developed in 1947. Ultimately, most patients died terribly, with many having infected both wives and children (Skloot 50, “Tuskegee Syphilis Study” 2017, CDC 2017).

“Hidden Science” in the Writings of Franklin & Conan Doyle

Men of method: Franklin and Conan Doyle

Benjamin Franklin. By Joseph Duplessi [Public domain], via Wikimedia Commons.
It was my first year of graduate studies, and I found myself re-reading The Autobiography of Benjamin Franklin. Some time had passed since I read this book in depth,[*] but certain portions remained clear enough in my mind, including Franklin’s ambitious and tongue-in-cheek project to acquire virtues in Part II.[†] As I read through this section, I felt a growing sense of familiarity that was related less to the content and more to the structure of the writing. Franklin’s project followed a pattern that I’d become familiar with while pursuing that other undergraduate degree:[‡] scientific methodology. Reading Part II of The Autobiography was not unlike reading a scientific paper: there was a section on the background and the project’s goal (“moral Perfection”; Franklin 1383), defined terminology, methods delineated (working on acquiring a single virtue on a weekly basis and recording instances of success/failure); results presented and discussed, and a conclusion or two (Franklin 1383–91), ranging from “I think I like a speckled Ax best” (Franklin 1390) to:

But on the whole, tho’ I never arrived at the Perfection I had been so ambitious of obtaining, but fell far short of it, yet I was by the Endeavour made a better and a happier Man than I otherwise should have been, if I had not attempted it (Franklin 1391).

Obviously, the project to acquire virtue wasn’t, per se, a scientific experiment, but it bore the hallmarks of one.

Elated that I observed something I previously hadn’t noticed, I wrote my short paper for the upcoming class with a reference to my discovery and mentioned it during my brief presentation. I, however, did not expect to be asked which approach to the scientific method had Franklin favored. My professor posed an excellent question, considering that the 17th and 18th century scientific thinkers were in the process of disputing more ancient methods (namely, Aristotelian) for deriving facts (Weinberg 201-14).[§] I, however, knew more about applying the basics of scientific methodology than its history.

Curiously, though, this experience—that is, the feeling I’d come across a familiar format— recurred when I re-read A Study in Scarlet for a recent post. Again, I felt as though I was reading about Sherlock Holmes conducting a scientific study in which he carefully observed the crime scene’s grounds (Conan Doyle 23–4), collected data (measurements at the murder site as well as examination of the murder victims; Conan Doyle 26, 29, 56–7), and even tested his theory that the first murder victims was poisoned (Conan Doyle 58–9). But, there it was: a sort of literary déjà vu featuring the scientific method. While I’m sure I understood that Holmes was both methodical and logical in his approach to detection, I doubt I noted the specific scientific underpinnings in Holmesian detective fiction when I was reading the stories in my early teens. It doesn’t seem like the sort of thing I would have considered independently when I was intent on consuming as many mystery novels as I could. And I certainly didn’t have the same ability to read critically as I do now.

Of course, detecting  the presence of scientific ideas in the writings of scientific men (Franklin, a scientist and inventor, and Conan Doyle, a medical doctor) isn’t unexpected, particularly with two individuals whom share the distinction of forwarding scientific study. Conan Doyle’s fiction anticipated the usage of methods that would become central in forensic sciences (eg, preserving footprints, protecting the crime scene from contamination)[††] and inspired forensic science pioneers like Edmond Locard (Steenberg 35).[‡‡] In Franklin’s case, the study of electricity benefited greatly from his attention to it (Chaplin), to put it mildly. Nonetheless, uncovering these connections between very different people writing for very different purposes was satisfying. I wouldn’t go so far to claim that I’ve seen further than some, but perhaps further than I once did.[§§] And I do feel a bit like a sleuth for detecting evidence of scientific thought.

[‡] For the curious, I have an undergraduate degree in Literature and one in Environmental Studies.

[§] Numerous sources discuss this critical change in scientific thinking, including the one I cite here (as a physicist, he brings an interesting perspective to exploring this history ). The scientific methodology has a long history and, of course, will continue to evolve as scientific discoveries and thought require it to do so. The link I provide depicts a concise timeline of important known events, dates, and person contributing to this evolution.

[**] Based on my limited research, I’d (tentatively) go with Francis Bacon. Franklin already was familiar with the self-improvement plans of notable intellectuals, including Bacon who was likely the most influential (Lemay 39). Considering that Bacon favored experiments to establish facts (empiricism), I think this dovetails neatly with Franklin’s process here. Oh, and not having an answer didn’t have any negative consequences for my classwork; it was just embarrassing.

[††]  Holmes use of footprint evidence seems amazingly prescient when you consider the SoleMate database of shoe prints.

Writing Holmes: How Conan Doyle Harnessed Hobbies for Sleuthing

“And that recommendation, with the exaggerated estimate of ability with which he prefaced it was, if you will believe me, Watson, the very first thing which ever made me feel that a profession might be made out of what had up to that time been the merest hobby.”

Sherlock Holmes, from “The ‘Gloria Scott’” by Sir Arthur Conan Doyle[*]

Sir Arthur Conan Doyle’s famous character, Sherlock Holmes looms large in detective fiction. Although he is based on Edgar Allan Poe’s C. Auguste Dupin,[†] Conan Doyle wrote far more extensively about his characters. Therefore, Holmes’s personality is developed to a greater degree. He has quirks—Holmes, often described as an eccentric, once shot “a patriotic V. R.” in his sitting room wall (“The Mustgrave Ritual”)[‡]—as well as vices (cocaine use) and hobbies. Of these, I find how authors of fiction use hobbies in their stories particularly interesting because hobbies represent a versatile means of characterization that can make a character more complex or succinctly communicate certain ideas about the character—almost like shorthand—that inform character behavior and even the narrative itself. In this first essay of a series that explores how writers use hobbies in fiction, I will discuss how Conan Doyle judiciously gave Holmes certain hobbies to create his great detective.

“The Merest Hobby”

Conan Doyle uses hobbies to accomplish much in the Holmes stories. For example, we learn that Holmes is talented violinist in A Study in Scarlet. Mentioned alongside his other pursuits, this hobby demonstrates the diversity of Holmes’s interests. Arguably, the violin also gives him an emotional outlet: Watson speculates that the strange violin solos may reflect Holmes’s moods. While such descriptions suggest Holmes’s complexity, there are three instances in which Conan Doyle actually uses the word hobby[§] that illustrate more about Holmes’s character and his profession.

In his first case (“The “Gloria Scott’”), Holmes describes his “habits of observation and inference” as “the merest hobby”. This opinion alters once Mr. Trevor, staggered by how much Holmes could infer about a stranger by mere observation, informs him “that all the detectives in fact and fiction would be children in your hand. That’s your line of life, sir.…” Devoted readers of Holmes know from The Sign of Four, published prior to this story, that Holmes considers observation and deduction to be “two out of the three qualities necessary for the ideal detective”. Rather than informing the reader about detecting, Conan Doyle inserts this epiphany to show both Holmes’s backstory (How did Holmes become a detective?) and his evolution. The younger Holmes, like so many others, once was clueless about his future after he finished college. But as Holmes matures, so does his hobby. “The merest hobby” proves to be the basis of Holmes’s career in disguise.

The Dilettante’s Hobby

But the idea that observation and deduction could be a “mere hobby” is an important consideration that Conan Doyle explores in a second instance where the word hobby appears. “The Greek Interpreter” introduces Mycroft Holmes, Sherlock’s elder brother, who apparently surpasses his younger sibling in these qualities. However, as Sherlock drily observes, “If the art of the detective began and ended with reasoning from an armchair, my brother would be the greatest criminal agent that ever lived”. Since Mycroft Holmes is a lazy man, both lacking the interest in confirming his theories and incapable of obtaining proof to support them, Sherlock dismisses his brother’s efforts as “the merest hobby of a dilettante”.

But Mycroft’s passivity allows him to act as Sherlock’s foil (i.e., the hobbyist versus the careerist) in another manner, as his aversion to exercise is contrasted to Sherlock’s energy. Clearly, Conan Doyle considered the physical abilities[**] a sleuth might need, keeping in mind the dangers connected to catching criminals. Hence, he provided Holmes with suitable hobbies that would make him fit to be a detective.[††] In Sherlock’s college days, his athletic interests were boxing and fencing (“The ‘Gloria Scott’”); Watson later describes Sherlock as “an expert singlestick player, boxer and swordsman” (A Study in Scarlet). As is seen with Holmes’s other “mere” hobby, these activities transform from sporting pastimes into useful tools for self-protection and/or subduing dangerous persons. From these examples, we can see that Conan Doyle uses this notion of hobby to delineate the difference between amateurs and professionals by insisting that a true detective needs to be an active investigator, seeking proof of his deductions and capable of handling whatever dangers and difficulties that arise during an investigation.

The Wearisome Hobby

Sherlock Holmes seeking clues.

The importance of seeking proof, however, naturally leads us back to the third quality of the “ideal detective”: knowledge. Holmes mentions to Watson that he (Holmes) has written monographs on tracing footprints and preserving them in plaster of Paris, distinguishing the various types of tobacco,[‡‡] and how different trades affect appearance of the human hand, a conversation he concludes by noting “But I weary you with my hobby.” To understand what Conan Doyle is doing here, we must unpack this scene further. Holmes’s monographs on “technical subjects” result from seeking this knowledge (The Sign of Four). As detailed in “The Mustgrave Ritual”, Holmes spent all his free time studying “all the branches of science that might make [him] more efficient” as a detective once he embarked on his career. And this knowledge (referring specifically to Holmes’s monographs and how they are useful for solving crimes and presenting evidence in court) is of “interest to the scientific detective”—meaning that Conan Doyle views the ideal detective as the scientific one (The Sign of Four).

This discussion of Holmes’s hobby, the writing of academic treatises on said “technical subjects”—what we’d know call forensic sciences—is important because it firmly establishes that Holmes’s detective work is based in a scientific approach. Although Holmes is not an academic, his work is of sufficient merit to be published for scientific community and this confers on him authority.[§§]. And he needs to claim this authority: Although his scientific studies are extensive, they are not attached to a specific degree program (A Study in Scarlet) since forensic sciences were not yet a formalized field of study. Similarly, Holmes is not a government detective, like Lestrade or Villard (the French detective who consulted Holmes and intends to translate his monographs; The Sign of Four). To justify their regard and validate Holmes’s presence at the crime scenes, it’s important to show that he has certain qualifications (observation, deduction and knowledge) that these regular detectives lack. To summarize, Holmes’s academic hobby neatly serves as his detecting credentials.

Conan Doyle’s compelling use of character hobbies serves multiple purposes in the Holmes tales. Beyond the role of providing character description, they define both Holmes and his approach to detective work: methodological observation, analysis and confirmation backed by scientific knowledge. But Holmes’s is not merely an academic or even armchair detective—he also possesses the necessary abilities to gain information, apprehend felons, and defend himself. He essentially is the fictional CSI of the Victorian era. And in this case, hobbies make the Holmes.

[*] For my quotes, I indicate the stories in which they appear because page numbers vary among the numerous anthologies, and it’s impractical to presume we’re all looking at the same book. For the record, the anthology I referred to was: Conan Doyle, Sir Arthur. Sherlock Holmes: The Complete Novels and Stories, Volume 1 and 2. 1920. Reprint. New York: Bantam Classics, 2003. Print.

[†] It’s well established that Conan Doyle loosely based Holmes and Watson on Poe’s Dupin and companion/roommate, respectively. For further reading, the reference lists of Holmes’s Wikipedia page is suggested—Wikipedia articles themselves are not good primary sources!

[‡] Yep, Holmes is that roommate. Also, this episode suggests that Holmes is a decent marksman.

[§] The three instances of the word hobby are discussed in their order of importance to the stories, not in order of story publication. Similarly, discussion of the actual hobbies tends to follow least to most important hobbies.

[**] This is not one of three qualities a detective must possess so much as a useful fourth.

[††] While Holmes’s marksmanship and acting ability are invaluable to his detective work, it’s difficult to term either as a hobby. We do know that Holmes started disguising himself as he grew famous, which—coupled with Holmes antisocial tendencies—signals that he adopted acting for his profession (The Sign of Four). For marksmanship, it’s unclear whether it was a sporting pastime prior to his career or again something he learned for his profession.

[‡‡] This monograph is also mentioned in A Study in Scarlet.

[§§] You could literally state that he doesn’t just know about tobacco ash, he wrote the book on it. Well, the monograph at any rate.
