Vox Meditantis

Dr Marie Maynard Daly (1921–2003) made history in 1947 as the first African American woman to earn a PhD in chemistry in the United States, breaking barriers that had barred countless brilliant minds before her. Her pioneering research not only cracked fundamental codes about DNA structure and protein synthesis but established the critical link between cholesterol and cardiovascular disease – work that forms the backbone of today’s heart attack prevention strategies. Yet despite reshaping both biochemistry and cardiology, her contributions remained largely obscured by the intersectional prejudices of her era, making her story both a triumph of scientific excellence and a stark reminder of how institutional barriers can silence transformative voices.

Dr Daly, it’s an honour to speak with you from 2025. Looking back, your career spans some of the most exciting decades in biochemistry – from the earliest days of DNA research through to modern cardiovascular science. What strikes me most is how you seemed to be at the centre of every major breakthrough, yet history has been frustratingly slow to recognise your contributions properly.

Well now, that’s quite an introduction! You know, when I was coming up in the 1940s, I wasn’t thinking about making history. I was just trying to solve puzzles that fascinated me. The idea that I was “making barriers fall” or any such thing – that wasn’t on my mind at all. I was working with Mary Caldwell at Columbia, studying how pancreatic amylase breaks down corn starch, and I was absolutely captivated by the chemistry of it all.

But you must have been aware you were the first Black woman to earn a chemistry PhD in America?

Not at the time! Can you believe it? It was 1947, and I was so focused on the work itself – those three years flew by – that I didn’t stop to think about firsts or lasts. In those days, you know, it was common for a woman to be addressed as “Miss” even though she’d earned a PhD degree. The whole business of recognition was quite different then. We were just grateful to be able to do the work we loved.youtube

Your father Ivan clearly had a profound influence on your path into chemistry. Can you tell us about that?

Oh, my father was everything to my scientific development. He’d come up from the West Indies with such dreams – enrolled at Cornell to study chemistry, just like I would later do. But the money ran out, as it did for so many of our families then. He had to leave his studies behind and take work as a postal clerk to support us. But he never let that dream die. He’d talk about chemistry at the dinner table, encourage me to read everything I could get my hands on. When I was visiting my grandparents in Washington, I found Paul de Kruif’s The Microbe Hunters in their library. My father had recommended it, and it absolutely set my imagination on fire – all those scientists hunting down the secrets of life itself.

And your mother Helen was equally supportive?

Mother was the one who read to me for hours, especially books about science. She understood that education was the key to everything. Both my parents had this unwavering belief – there’s that word you don’t like – this absolute conviction that knowledge could change our circumstances. They made sure I knew that my mind was my greatest asset.

Let’s talk about your most technical contribution – your work on histones with Alfred Mirsky at Rockefeller. For our readers, could you walk us through exactly what you discovered?

Now that was the most thrilling period of my career! Seven years at Rockefeller – it was like being in the epicentre of biological discovery. When I started working with Alfred Mirsky and Vincent Allfrey in 1948, we were investigating the composition of cell nuclei at a time when most scientists barely understood what DNA actually did.

My primary contribution was developing new fractionation methods to isolate and characterise different types of histones. You have to understand, this was 1951, and we were working with calf thymus, calf liver, and fowl erythrocytes. I showed that histones had remarkably similar amino acid compositions across species – except that fowl erythrocyte histone completely lacked methionine, while other histones contained only 0.47 to 0.69 mole percent.

That seems like a small detail, but it was significant?

Absolutely crucial! We were establishing that histones weren’t just random nuclear proteins – they had specific, conserved functions. More importantly, I identified two distinct classes: the classical arginine-rich histones everyone knew about, and what I termed “lysine-rich histones”. These lysine-rich varieties dissociated much more readily from nucleic acids than the arginine-rich ones. This suggested they played different regulatory roles in how DNA was packaged and accessed.

And this work was acknowledged by Watson and Crick?

Indeed it was! Our 1953 paper with Vincent Allfrey on protein synthesis – showing that ribonucleoproteins were essential for protein production – was cited in James Watson’s Nobel Prize lecture. We’d demonstrated that protein synthesis required RNA, which was fundamental to understanding how genetic information gets translated into actual cellular machinery. At the time, remember, the structure of DNA had only just been worked out. We were simultaneously discovering what DNA was made of and how it functioned.

You also identified the key nucleotide bases in DNA?

That’s right. Through our sophisticated extraction methods, I confirmed that adenine, guanine, thymine, and cytosine were the primary building blocks of DNA, and crucially, that these bases appeared in consistent proportions across all life forms. Sounds simple now, but in 1951, that was groundbreaking information about the universal chemistry of heredity.

Moving to your cardiovascular work – this seems like quite a leap from DNA research.

Not as much as you might think! Both involved understanding the chemistry underlying life processes. In 1955, I returned to Columbia to work with Quentin Deming, who was investigating the causes of heart attacks. We moved together to Albert Einstein College of Medicine in 1958, and that’s where we made our most significant discoveries about cholesterol and atherosclerosis.

Walk us through that research methodology.

We used experimental rat models where we could control diet and measure multiple variables simultaneously – blood cholesterol levels, blood pressure, and arterial damage. This was quite innovative at the time. We could induce hypertension using desoxycorticosterone and salt, then observe how this accelerated the development of hypercholesterolemia and tissue cholesterol accumulation.

Our key finding was establishing the relationship between dietary cholesterol and arterial clogging, but more importantly, we showed that hypertension was a precursor to atherosclerosis, not just a consequence. High blood pressure didn’t just accompany heart disease – it actually accelerated the process by which cholesterol deposits formed arterial blockages.

What were the measurable advantages of your approach over previous methods?

Earlier cardiovascular research was largely observational and clinical. We brought rigorous biochemical analysis to the field. We could quantify cholesterol levels, measure blood pressure changes over time, and most importantly, correlate these with actual arterial pathology. We also investigated the effects of different dietary components – not just cholesterol, but sugar and other nutrients – on the circulatory system.

Did you encounter resistance to these findings?

Some, certainly. The medical establishment was still quite focused on treating symptoms rather than understanding underlying biochemical mechanisms. I remember telling a reporter that I wasn’t working on cancers per se – I was doing research on cell growth, and my work concerned cancer only insofar as cancer involved cell growth. The same principle applied to cardiovascular work. We were investigating fundamental metabolic processes, not just clinical presentations.

You also studied the effects of cigarette smoking on cardiovascular health quite early.

Yes, we were among the first to document how cigarette smoke affected both lung tissue and the cardiovascular system. This was in the early 1960s, well before the broader medical consensus on smoking dangers. Our laboratory could measure the direct chemical effects on tissue samples, providing concrete evidence for what many suspected but couldn’t prove.

In your later years, you focused on creatine uptake by muscle cells.

That came in the 1970s. Creatine is essential for muscle energy recycling – the phosphocreatine system that provides quick bursts of cellular energy. My 1980 paper described the optimal conditions for muscle tissue to absorb creatine. Again, this was biochemistry applied to understanding fundamental life processes. Athletes and medical researchers use these findings today for performance enhancement and treating muscle disorders.

Looking back, is there anything you’d do differently? Any mistakes you can now acknowledge?

Well, I think I was sometimes too focused on the pure science and not enough on the broader implications. When we were discovering the cholesterol-atherosclerosis connection, I was fascinated by the biochemical mechanisms. But I didn’t spend enough time considering how this information might be translated into public health recommendations. It took decades for our findings to influence dietary guidelines and preventive cardiology.

Also, I’ll admit I was perhaps too accommodating of institutional barriers. I was so grateful to be able to do the work that I didn’t always challenge the systems that made it unnecessarily difficult for others like me.

What was it like being one of the few women of colour in these research environments?

Lonely, much of the time. At Rockefeller, I was working with brilliant scientists, but I was often the only person who looked like me in the room. You learn to be twice as prepared, twice as careful with your data, because you know any mistake will be magnified. But I was fortunate to work with people like Mary Caldwell and Alfred Mirsky, who judged me on the quality of my work, not on preconceptions.

You became quite involved in efforts to increase diversity in science.

That became increasingly important to me as my career progressed. In 1975, I participated in a conference organised by the American Association for the Advancement of Science about the challenges facing minority women in science. We produced a report called The Double Bind: The Price of Being a Minority Woman in Science. The title says it all – we faced both racial and gender discrimination simultaneously.

At Albert Einstein, I spearheaded efforts to recruit and support Black and Puerto Rican medical students. I knew firsthand how isolating those environments could be, and how important it was to have mentors who understood your experience.

And you established a scholarship fund at Queens College?

In 1988, in honour of my father. I wanted to help minority students studying chemistry and physics – the same fields my father had to abandon due to financial constraints. I felt that scholarship money coming from a Black scientist might be particularly motivating to Black students. Representation matters enormously. When you can see someone who looks like you succeeding in a field, it makes that path seem possible.

What do you think about how your field has evolved since your retirement in 1986?

The advances in cardiovascular medicine have been remarkable! The development of statins, for instance, builds directly on our early work linking cholesterol to arterial disease. Modern cardiometabolic research, prevention protocols, the understanding of inflammation’s role in atherosclerosis – it’s all connected to those fundamental discoveries we made in the 1950s and 60s.

And the techniques we developed for studying histones? That work laid groundwork for today’s understanding of epigenetics – how gene expression is regulated without changing DNA sequences. It’s thrilling to see how basic biochemistry has blossomed into these sophisticated fields.

Do you have advice for today’s scientists, particularly women and minorities entering STEM?

First, remember that curiosity is your greatest asset. Don’t let anyone convince you that certain questions are too difficult or not for people “like you.” Some of my best discoveries came from asking seemingly simple questions and pursuing them rigorously.

Second, find mentors and be a mentor. Mary Caldwell showed me that women could excel in chemistry departments. Alfred Mirsky demonstrated how to approach big scientific questions methodically. Later, I tried to provide that same guidance to minority medical students.

Finally, don’t underestimate the power of persistence. Science is about solving problems incrementally. Every experiment teaches you something, even when – especially when – it doesn’t work as expected.

Any particular frustrations with how history has remembered your contributions?

Well, it’s interesting that you mention Watson and Crick citing our work on protein synthesis. They received the Nobel Prize, but how many people know that a Black woman’s research helped establish the foundations of molecular biology? That’s not bitterness speaking – it’s simply a fact about how recognition works in science.

But I’m encouraged by recent developments. The American Chemical Society named me a National Historic Chemical Landmark in 2023. There are more women and people of colour in chemistry than ever before. Change happens slowly, but it does happen.

What would you want young scientists today to understand about the intersection of scientific achievement and social progress?

Science doesn’t exist in a vacuum. The questions we ask, the problems we prioritise, the way we interpret data – all of this is influenced by who’s in the room making those decisions. When I was studying cardiovascular disease, I was thinking about my community, where heart disease was a major killer but research was limited. Diversity isn’t just about fairness – it’s about better science.

Every time a young person from an underrepresented group enters STEM, they bring questions and perspectives that might not otherwise be considered. That’s how we make discoveries that benefit everyone.

Dr Daly, thank you for this conversation. Your work truly did reshape our understanding of life’s fundamental processes.

Thank you. You know, at the end of the day, I was just a girl from Queens who loved solving puzzles. But if my story can encourage others to pursue their own scientific curiosity, regardless of the barriers they might face, then perhaps that’s the most important contribution of all.

Letters and emails

Following our conversation with Dr Marie Maynard Daly, we’ve received an overwhelming response from readers eager to explore different aspects of her remarkable career and lasting influence on modern science. We’ve selected five letters and emails from our growing community who want to ask her more about her life, her work, and what she might say to those walking in her footsteps.

Awa Diop, 34, Public Health Researcher, Dakar, Senegal:
Dr Daly, your cardiovascular research identified crucial links between diet and heart disease decades before modern nutritional science caught up. Given that cardiovascular disease remains a leading killer globally, particularly in developing nations where Western dietary patterns are spreading rapidly, what specific dietary interventions would you prioritise if you were designing public health campaigns today?

Miss Diop, your question strikes right at the heart of what kept me up nights during my later years at Einstein. You’re absolutely right that we identified these dietary connections decades before the medical establishment truly embraced them, and it pains me to see cardiovascular disease still claiming so many lives, particularly in communities that remind me of my own.

If I were designing public health campaigns today, I’d focus first on what we learned about the sugar-cholesterol connection. Back in the 1960s, we weren’t just looking at dietary cholesterol – we were investigating how refined sugars affected the entire lipid profile. The work we did with Quentin Deming showed that high sugar intake could be just as dangerous as high cholesterol foods, but this got buried under all the focus on saturated fats. I’d want campaigns to emphasise reducing processed foods and refined sugars, not just avoiding eggs and butter.

Second, I’d push hard for community-based interventions rather than individual behaviour change. You know, when I was growing up in Corona, Queens, my mother cooked everything from scratch because that’s what families did then. We didn’t have fast food chains on every corner or convenience stores filled with processed meals. The problem isn’t that people don’t know vegetables are good for them – it’s that healthy food has become expensive and inconvenient whilst unhealthy options are cheap and accessible.

I’d also focus campaigns on hypertension as the silent precursor to heart disease. Our research showed clearly that high blood pressure accelerated atherosclerosis, yet so many people – especially in Black and brown communities – walk around with undiagnosed hypertension. Regular blood pressure screening should be as common as checking your temperature.

Most importantly, I’d ensure these campaigns are led by people from the communities they’re meant to serve. When I was working with minority medical students at Einstein, I learned that trust matters enormously. A public health message delivered by someone who looks like you, who understands your cultural food traditions and economic constraints, carries far more weight than the same message from an outsider.

The tragedy is that much of what we discovered in the 1950s and 60s could have prevented millions of premature deaths if it had been translated into accessible, culturally appropriate public health interventions. We had the science; what we lacked was the will to ensure it reached the people who needed it most. That’s the real challenge facing public health today – not discovering new knowledge, but making sure existing knowledge serves everyone equally.

Brandon Lewis, 41, Biomedical Engineer, Toronto, Canada:
I’m curious about the technical limitations you faced when isolating histones in the 1950s. Today we have sophisticated chromatography and mass spectrometry techniques that can identify protein modifications at the single-molecule level. If you could revisit your histone research with modern instrumentation, what specific questions about gene regulation would you want to tackle first?

Mr Lewis, you’ve touched on something that still fascinates me – the sheer crudeness of our methods compared to what’s available now. When Vincent Allfrey and I were working on histone isolation at Rockefeller in the early 1950s, we were essentially using glorified kitchen chemistry. We’d extract proteins using salt solutions, separate them by precipitation, and analyse their amino acid composition through paper chromatography. Each experiment took weeks, and we were lucky if we could identify the major components with any precision.

The most frustrating limitation was our inability to see what these proteins were actually doing in real time. We could isolate histones and show they bound to DNA, but we couldn’t watch gene regulation happen. We suspected that different histone types controlled which genes were active, but proving it required indirect evidence – measuring protein synthesis under different conditions, then inferring what must have occurred.

If I had access to your modern instrumentation, the first question I’d tackle would be the dynamic nature of histone modifications. We knew histones weren’t static – they had to change somehow to allow genes to turn on and off. But we couldn’t see those modifications happening. With today’s mass spectrometry, I’d want to track exactly how histone methylation and acetylation patterns change during cell division, development, and in response to environmental stress.

The second area would be species-specific differences. Remember, I found that fowl erythrocyte histones completely lacked methionine while mammalian histones contained small amounts. At the time, we thought this might be just a curious biochemical variation. Now I suspect it reflects fundamental differences in how different organisms regulate gene expression. Modern techniques could map these variations across hundreds of species and correlate them with specific regulatory mechanisms.

Most intriguingly, I’d investigate the connection between histone chemistry and disease. We were working in the dark ages when it came to understanding how genetic regulation goes wrong in cancer or other disorders. If histone modifications control which genes are active, then abnormal histone chemistry might cause abnormal gene expression patterns. This could explain how cells become cancerous or why some people are susceptible to certain diseases.

The irony is that our crude methods forced us to think more carefully about each experiment. We couldn’t just generate massive datasets and hope patterns would emerge – every measurement had to be planned meticulously because materials and time were so precious. Sometimes I wonder if that constraint actually made us better scientists.

Natalia Kowalska, 28, Ethics Professor, Warsaw, Poland:
Your experience as both a pioneering scientist and an advocate for minority students raises fascinating questions about responsibility. Do you think exceptional individuals who break barriers have an obligation to actively mentor others from their communities, or should they be free to focus solely on their research? How did you balance these competing demands on your time and energy?

Miss Kowalska, you’ve asked me perhaps the most difficult question I faced throughout my career. The truth is, I didn’t choose to become a mentor – circumstances forced it upon me, and I often resented the additional burden.

When I started at Rockefeller in 1948, I was focused entirely on the science. I wanted to prove myself through my research, to be judged solely on the quality of my work with Alfred Mirsky. But it became clear quite quickly that my very presence in those laboratories meant something to other people. Young women, particularly women of colour, would seek me out at conferences or write letters asking for advice. I hadn’t asked for that responsibility, but there it was.

For years, I tried to maintain boundaries. I’d tell myself that my primary obligation was to advance scientific knowledge, and that if I succeeded spectacularly enough, I’d open doors for others simply by example. This wasn’t entirely selfish thinking – I genuinely believed that excellence was the best advocacy. But it was also convenient reasoning that allowed me to avoid the messy, time-consuming work of active mentorship.

The turning point came when I moved to Albert Einstein in 1958. Suddenly I was surrounded by medical students, many struggling with the same isolation I’d experienced. These weren’t abstract requests for advice – these were young people in my own institution who needed immediate support. I couldn’t pretend that wasn’t my concern.

But here’s what I learned: mentorship isn’t charity work that detracts from research – it actually enhanced my scientific thinking. Working with students forced me to articulate my methods more clearly, to question assumptions I’d taken for granted. Some of my best insights about cardiovascular research came from explaining complex concepts to medical students who asked naive but penetrating questions.

The ethical obligation, I think, isn’t to sacrifice your research for mentorship, but to recognise that the two can be mutually reinforcing. When I helped establish that scholarship fund at Queens College, I wasn’t just being altruistic – I was investing in the future of my field. Science advances faster when it includes diverse perspectives and experiences.

That said, the burden shouldn’t fall disproportionately on those who are already fighting upstream battles. Institutions need to create structures that support mentorship rather than expecting pioneering individuals to shoulder this responsibility alone. The real ethical question isn’t whether exceptional people have obligations to their communities, but whether society has an obligation to ensure that exceptional people from all backgrounds can thrive without having to choose between personal achievement and collective advancement.

Carlos Benítez, 37, Science Policy Analyst, Buenos Aires, Argentina:
Here’s a hypothetical scenario: imagine you could travel back to 1947 with knowledge of everything that would unfold in biochemistry over the following decades – the double helix structure, the genetic code, PCR technology, even CRISPR gene editing. Which single piece of future knowledge would you choose to bring back to accelerate your research, and how might that have changed the trajectory of molecular biology?

Mr Benítez, what a tantalising thought experiment! You know, I’ve often wondered how different things might have been if we’d understood the full picture earlier. But after considering your question carefully, I think I’d choose to bring back knowledge of the genetic code – the exact relationship between DNA sequences and protein structure.

Here’s why: in 1947, when I was finishing my PhD work on pancreatic amylase, we knew proteins were important but had no idea how cells actually made them. We suspected nucleic acids were involved somehow, but the mechanism was completely mysterious. If I’d known that specific three-letter DNA sequences coded for specific amino acids, it would have transformed everything we were doing at Rockefeller.

Think about it – when Alfred Mirsky and I were studying histones in the early 1950s, we were essentially working backwards. We’d isolate these proteins, analyse their amino acid composition, and try to guess what they did based on where we found them. But if I’d known the genetic code, I could have predicted histone sequences, understood why certain amino acids appeared in specific ratios, and grasped immediately that these proteins were gene regulators, not just nuclear packing material.

More importantly, it would have accelerated the entire field of molecular biology by decades. James Watson and Francis Crick published their DNA structure in 1953, but it took another thirteen years before Marshall Nirenberg and Har Gobind Khorana fully cracked the genetic code. If that knowledge had been available in 1947, we could have jumped straight from DNA structure to understanding protein synthesis.

The ripple effects would have been extraordinary. My cardiovascular work with Quentin Deming in the 1960s might have identified the specific genes involved in cholesterol metabolism. We could have developed targeted therapies much earlier, potentially preventing millions of heart attacks. The histone research could have led immediately to understanding epigenetic regulation, revolutionising cancer treatment and developmental biology.

But here’s what really intrigues me about your scenario: having that knowledge might have changed who got credit for discoveries. If a Black woman had been making genetic code predictions in 1947, would the scientific establishment have taken me seriously? Or would my insights have been dismissed until white male scientists “rediscovered” them years later?

Perhaps the most profound change wouldn’t have been scientific but social – demonstrating that transformative discoveries could come from anyone, regardless of their background, might have forced science to become more inclusive much sooner.

Farah Nazari, 45, Pharmaceutical Chemist, Kuala Lumpur, Malaysia:
The pharmaceutical industry now generates billions in revenue from statin drugs that build directly on your cholesterol-atherosclerosis research. Yet many of the scientists whose foundational work enabled these breakthroughs – particularly women and minorities – received little financial recognition. How do you think the scientific community should address this pattern of unequal credit and compensation?

Dr Nazari, you’ve raised something that has troubled me deeply, particularly as I’ve watched the pharmaceutical industry flourish in ways we never imagined back in the 1960s. When Quentin Deming and I were establishing the cholesterol-atherosclerosis connection, we were driven purely by scientific curiosity and the desire to prevent human suffering. The idea that our work would generate billions in profits never crossed our minds.

It’s both gratifying and disturbing to see how our research became the foundation for an entire class of drugs. On one hand, statins have undoubtedly saved millions of lives – exactly what we hoped our work would accomplish. On the other hand, the financial rewards have gone almost entirely to pharmaceutical companies and the scientists they employed to develop specific compounds, whilst those of us who established the basic science received nothing beyond our academic salaries.

But the pattern you’ve identified goes deeper than just financial recognition. It’s about whose contributions get remembered and valorised. The development of statins required not just our foundational research on cholesterol metabolism, but work by countless other scientists – many of them women, many from minority backgrounds – who studied lipid biochemistry, arterial physiology, and drug metabolism. Yet the pharmaceutical industry’s success stories typically highlight a few key figures, usually white men who worked for major drug companies.

I think the scientific community needs to fundamentally rethink how we assign credit and compensation. Perhaps there should be royalty systems for foundational research that enabled commercial applications, similar to how inventors receive patent royalties. Or maybe pharmaceutical companies should be required to establish funds that support basic research and education in the communities where foundational discoveries were made.

More broadly, we need to change how we tell the stories of scientific achievement. When companies market statins, they should acknowledge the decades of basic research that made those drugs possible. When medical schools teach about cardiovascular disease, they should mention not just the clinical trials that proved statin efficacy, but the earlier work that identified cholesterol as a therapeutic target.

The most troubling aspect isn’t just that women and minorities receive less financial benefit – it’s that this pattern discourages young people from our communities from entering science. If they see that foundational contributions go unrecognised whilst commercial applications bring fame and fortune, why would they choose the uncertain path of basic research?

Science advances through collective effort across generations, but our reward systems treat it as individual achievement within corporations. Until we address this fundamental disconnect, we’ll continue to see brilliant minds from underrepresented communities choose other fields where their contributions might be more fairly recognised and compensated.

Reflection

Dr Marie Maynard Daly passed away on 28th October 2003 at age 82, leaving behind a scientific legacy that continues to shape how we understand life itself. Through this fictional conversation, we’ve explored not just her groundbreaking discoveries but the profound human cost of brilliance constrained by prejudice.

What emerges most powerfully is Daly’s pragmatic approach to barriers that might have crushed others. Rather than positioning herself as a crusader against injustice, she focused relentlessly on the science – a strategy that enabled her contributions whilst perhaps limiting their recognition. Her reflections on mentorship reveal the impossible choices faced by pioneering women of colour: excel individually or lift others collectively, knowing that energy spent on either might compromise the other.

The historical record, whilst documenting her achievements, often glosses over the daily indignities and institutional isolation she endured. Her work at Rockefeller Institute placed her at the epicentre of molecular biology’s birth, yet textbooks rarely mention her histone research alongside Watson and Crick’s more famous discoveries. This pattern – foundational work by women and minorities being overshadowed by later, more celebrated contributions – remains frustratingly persistent.

Today’s cardiovascular medicine stands directly on Daly’s shoulders. Every statin prescription, every dietary guideline linking cholesterol to heart disease, every public health campaign targeting hypertension traces back to her laboratory bench in the 1950s and 60s. Her scholarship fund at Queens College continues supporting minority students in chemistry and physics, ensuring her father’s thwarted dreams find new expression in each generation.

Perhaps most remarkably, Daly’s story illuminates how scientific progress depends not just on individual genius but on creating conditions where that genius can flourish regardless of its origins. Her legacy challenges us to ask: how many other transformative discoveries remain locked away, waiting for barriers to fall?

Who have we missed?
