This is a 12-panel graphic novel about Alice Catherine Evans (1881–1975), an American microbiologist who discovered that the bacterium Brucella in raw cow's milk is the same organism causing undulant fever (brucellosis) in humans — a finding that led, after years of fierce industry opposition, to mandatory pasteurization in the United States. The story spans her rural Pennsylvania childhood, her Cornell University education, her assignment to dairy research at the USDA, her 1917 discovery, the decade-long backlash from the dairy industry and skeptical male scientists, her personal contraction of brucellosis, the slow vindication of her findings, and her ultimate legacy as a pioneer of food safety science. The art style is Early Modern American illustration — clean, precise, documentary — with a contrast between stark black-and-white newsprint aesthetic (used for backlash and public controversy scenes) and warm amber laboratory tones (used for scientific work scenes). Alice is depicted consistently as a slight woman with short wavy hair, wire-rimmed glasses, and a white lab coat. Maintain character consistency across all panels.Prologue – The Glass of Milk That Changed Everything¶
Every morning, millions of children in America drink a glass of cold, safe milk without a second thought. That safety was not always guaranteed — and it was not given to them by the dairy industry. It was won by one determined microbiologist who spent years being told she was wrong, she was unqualified, and she simply did not understand the science. Her name was Alice Catherine Evans, and she was right all along.
Panel 1: A Farm Girl Who Wanted More¶
Image Prompt
(This is Panel 1 of 12. Do not include the panel number in the image.) Wide 16:9 landscape panel in Early Modern American illustration style — clean pen-and-ink lines with warm sepia and amber watercolor washes. Setting: a working farm in Neath, Pennsylvania, circa 1890. A young girl of about 9 — Alice Evans — in a plain cotton farm dress and leather boots, stands at the split-rail fence of a cow pasture, watching a herd of black-and-white Holstein cows with intense, studying eyes. She holds a small hand-drawn notebook and is carefully sketching one of the cows. Her older brother works in the background, tossing hay. The Pennsylvania countryside behind her is golden in late-afternoon autumn light — rolling hills, a red barn, a stone farmhouse. Color palette: warm autumn gold, deep Pennsylvania green, the black-and-white pattern of Holstein cattle, sepia and amber tones throughout. Mood: observant, quietly intellectual, the roots of scientific curiosity in a farm setting. Visual details: split-rail fence, Holstein cows in pasture, hand-drawn notebook with a child's cow sketch, leather ankle boots, hay-tossing brother in background, red barn and stone farmhouse, rolling Pennsylvania hills. Generate the image immediately without asking clarifying questions.Alice Catherine Evans was born in 1881 in Neath, Pennsylvania, the daughter of Welsh immigrant farmers who valued education even when money was scarce. Growing up on a working farm gave Alice an intimate familiarity with the animals and agricultural processes that would later define her scientific career — she knew what healthy cows looked like, how milk was collected, and what "off" milk smelled and tasted like from earliest childhood. But farm life also showed her the limits placed on girls who were curious: formal higher education was expensive, distant, and considered, by many neighbors, unnecessary for a woman who would simply marry a farmer. Alice had other plans.
Panel 2: The Long Road to Cornell¶
Image Prompt
(This is Panel 2 of 12. Do not include the panel number in the image.) Wide 16:9 landscape panel in Early American illustration style with a split-panel narrative design. Setting: two scenes side by side. Left scene — a rural Pennsylvania one-room schoolhouse, circa 1895, where a teenage Alice sits at the back of the classroom teaching younger children their letters, herself only a few years older than them, her own textbooks open beside the students' primers. Right scene — the same Alice, now about 22, seated at a desk in a bright dormitory room at the Cornell University campus (shown through the window with Victorian Gothic architecture), surrounded by college textbooks, writing with focused intensity. A letter on her desk reads "NEW YORK STATE SCHOLARSHIP FOR COUNTRY TEACHERS." Color palette: warm sepia and amber tones for the rural scene, cooler blue-grey academic tones for Cornell, both lit by different quality of light that implies different worlds. Mood: the determined arc of self-education, constrained opportunity transformed into advancement. Visual details: one-room schoolhouse with younger pupils, Alice teaching at the chalkboard, scholarship letter visible in desk scene, Cornell Gothic architecture through window, college textbooks stacked high, oil lamp on the dormitory desk. Generate the image immediately without asking clarifying questions.Alice's path to university was not direct — few paths were for rural women in the 1890s. She spent years teaching at a local school to save money, then qualified for a free nature-study course at Cornell University designed for rural teachers. That one course ignited a hunger she could not extinguish. She enrolled in Cornell's College of Agriculture, one of the few departments in America that accepted women into full degree programs, and graduated in 1909 with a Bachelor of Science in bacteriology. She then completed a Master of Science degree at the University of Wisconsin in 1910 — and immediately joined the United States Department of Agriculture's Bureau of Animal Industry, assigned to dairy bacteriology research.
Panel 3: The "Women's Work" of Dairy Science¶
Image Prompt
(This is Panel 3 of 12. Do not include the panel number in the image.) Wide 16:9 landscape panel in 1910s American scientific illustration style — clean, precise, slightly clinical. Setting: the USDA Bureau of Animal Industry dairy laboratory, Washington D.C., circa 1913. The laboratory is a long, well-lit room with white tile walls and rows of scientific equipment — microscopes, culture flasks, Bunsen burners, centrifuges. Alice Evans, a slight woman in her early 30s wearing a white lab coat over a high-collar blouse with a cameo brooch, works at her microscope bench. Around her, several male scientists in their own lab coats work at other stations — one of them, in the foreground, gestures dismissively toward Alice's bench while talking to a colleague, not bothering to lower his voice. A small handwritten card on Alice's bench reads "DAIRY BACTERIOLOGY." Alice is looking through her microscope, apparently oblivious to the dismissal, but a slight tension in her jaw tells a different story. Color palette: clinical white, steel grey equipment, warm amber microscope lamp, pale morning light from tall windows. Mood: professional isolation, quiet persistence, condescension that will prove costly. Visual details: binocular microscope with oil-immersion lens, row of glass culture tubes in a rack, male colleague gesturing dismissively in foreground, "DAIRY BACTERIOLOGY" card on bench, centrifuge in background, high-collar blouse with cameo brooch, white tile laboratory walls. Generate the image immediately without asking clarifying questions.At the USDA, Alice Evans was assigned to dairy research not because of particular expertise — but because her supervisors considered dairy bacteriology to be "women's work," suitable for a female researcher who had no PhD and therefore could not be trusted with more "important" investigations. The irony is exquisite: this dismissive assignment placed the right scientist in exactly the right place to make one of the most important public health discoveries of the twentieth century. Alice dove into the microscopic world of dairy bacteria with the same focused intensity she had brought to every challenge in her life — examining milk samples, culturing bacteria, comparing the organisms she found to published descriptions of known pathogens.
Panel 4: The Discovery That Changed Everything¶
Image Prompt
(This is Panel 4 of 12. Do not include the panel number in the image.) Wide 16:9 landscape panel in the style of a dramatic 1910s scientific illustration — precise microscope imagery blended with a revelation moment. Setting: Alice Evans's laboratory bench at the USDA, Washington D.C., 1917. Alice is bent over her microscope in the late evening — the lab is otherwise dark and empty, lit only by her microscope lamp and the light over her bench. She has two sets of open laboratory notebooks side by side: one labeled "BOVINE MILK SAMPLES — Brucella abortus cultures," the other labeled "HUMAN UNDULANT FEVER — Micrococcus melitensis." She is pointing with her pencil from one page to the other, and her eyes are wide. On a large comparison chart she has drawn by hand, two columns of bacterial characteristics — shape, growth pattern, staining properties — are annotated with handwritten notes showing they match perfectly. The expression on her face is the rare look of a scientist who has just seen something no one has seen before. Color palette: warm amber lamp light against the deep darkness of the empty evening lab, white pages of notebooks gleaming, shadows on her face deepening the drama. Mood: electrifying discovery, the world about to change, solitary genius. Visual details: two open laboratory notebooks with handwritten data, microscope with amber light, hand-drawn comparison chart showing matching bacterial characteristics, pencil pointing between pages, darkened empty laboratory behind her, steaming coffee cup suggesting long hours worked. Generate the image immediately without asking clarifying questions.In 1917, Alice Evans made a discovery so significant that she initially could not believe it herself. Examining the bacteria she had cultured from raw cow's milk — Brucella abortus, known to cause spontaneous abortion in cattle — she compared them systematically to the bacteria causing "undulant fever" in humans, a mysterious illness characterized by waves of fever, joint pain, and extreme fatigue. The characteristics matched. The bacterium causing undulant fever in humans was not a different organism at all — it was essentially the same bacterium present in the raw milk that millions of Americans drank every day. She checked her results again and again. The data were clear. Raw milk was making people sick, and nobody in the dairy industry wanted to know about it.
Panel 5: The Paper That Caused a Storm¶
Image Prompt
(This is Panel 5 of 12. Do not include the panel number in the image.) Wide 16:9 landscape panel with a dramatic split composition — the left side in warm amber laboratory tones, the right side in stark black-and-white newsprint style. Setting: left half shows Alice Evans at her laboratory bench writing carefully in ink, surrounded by culture plates, microscopy notes, and the finished manuscript of her 1918 research paper. Right half shows the same paper's title page — "The Pathogenic Bacteria in Raw Milk" — and below it, a swarm of black-and-white illustrated figures in a storm: angry dairy industry executives in suits shaking fists, male scientists shaking their heads with crossed arms, newspaper headlines reading "WOMAN RESEARCHER ATTACKS MILK INDUSTRY" and "NO PhD — WHO IS SHE TO SAY?" Alice's small, calm figure on the left is framed by warm light, unmoved, while the storm rages on the right. Color palette: warm amber for Alice's laboratory work, harsh black-and-white for the backlash, the manuscript page itself a transition between the two. Mood: the courage of publication, the cost of truth. Visual details: manuscript pages with handwritten title and careful ink text, culture plates and microscopy slides on bench, angry industry figure silhouettes on the right half, newspaper headlines in bold serif type, stack of research papers, Alice's pen still in hand. Generate the image immediately without asking clarifying questions.Alice Evans submitted her findings to the Journal of Infectious Diseases in 1918. The reaction was immediate and brutal. The dairy industry attacked her credentials — she had no PhD, they pointed out repeatedly, as if that changed the data in her petri dishes. Prominent male scientists dismissed her findings, with some suggesting she had simply made technical errors. Others implied that a woman assigned to study butter and cheese could not possibly understand the subtleties of human pathogen identification. The economic stakes were enormous: mandatory pasteurization of milk would cost the dairy industry millions of dollars in equipment upgrades. So the industry fought back — not by disproving her science, but by attacking the scientist.
Panel 6: The Backlash¶
Image Prompt
(This is Panel 6 of 12. Do not include the panel number in the image.) Wide 16:9 landscape panel in 1920s American editorial cartoon style — bold, stark, almost caricatured for dramatic effect. Setting: a formal scientific conference room, circa 1920. Alice Evans stands at a podium presenting her findings before a large audience of scientists in dark suits. She has put up a chart showing the correlation between raw milk consumption and undulant fever cases. But the audience's reaction is hostile — several men in the front row have their arms crossed and expressions of contemptuous dismissal. One large man in the front row holds up a sign that reads "NO PhD — UNQUALIFIED." Behind Alice on the podium, a smaller figure — her USDA supervisor — stands with hands spread helplessly. A dairy industry representative in the back row, identifiable by a small "DAIRY LOBBY" badge, whispers to the man beside him. Only a few attentive faces in the crowd seem to be actually listening to her data. Color palette: stark dark suits and formal conference room, harsh electric ceiling light, Alice in white lab coat as a visual contrast to the dark-suited men. Mood: confrontation, isolation, the grinding unfairness of expertise dismissed. Visual details: presentation chart showing milk/fever correlation, "NO PhD — UNQUALIFIED" placard, hostile crossed-arms postures in audience, dairy lobby representative whispering, helpless supervisor behind Alice, a few attentive listeners scattered in the crowd. Generate the image immediately without asking clarifying questions.For years, Alice Evans presented her evidence at scientific conferences and in published papers, and for years she was dismissed, mocked, or ignored. The American dairy industry's influence was enormous — milk was marketed as "nature's perfect food," and any suggestion that it could cause illness was treated as an attack on American farming itself. Some scientists did attempt to replicate her experiments but failed initially, due to differences in bacterial strains or technical methods — which the industry seized on as proof that she was wrong. Evans continued refining her methods and expanding her data set, becoming more certain with every passing year that she was right and that people were dying because she was being ignored.
Panel 7: The Scientist Falls Ill¶
Image Prompt
(This is Panel 7 of 12. Do not include the panel number in the image.) Wide 16:9 landscape panel in a somber, muted 1920s illustration style. Setting: Alice Evans's laboratory at the USDA, 1922. Alice is seated at her bench but is visibly unwell — her face is pale and drawn, her posture slightly hunched, and she has a thermometer and a glass of water at her elbow alongside her research materials. Despite clearly being ill, she is still working — reviewing bacterial culture results, making notes, refusing to stop. A calendar on the wall shows 1922. A doctor's note is pinned beside it reading "UNDULANT FEVER — REST REQUIRED." But the lab notebook is open and her pen is in her hand. A single detail makes the irony vivid: on the shelf above her desk, a framed copy of her 1918 research paper stares down at her. Color palette: muted greys and pale yellows of illness, warm amber of the laboratory lamp, the white of the research paper's frame standing out clearly. Mood: painful irony, stubborn determination, the scientist living her own hypothesis. Visual details: thermometer and water glass beside research materials, pale ill complexion, doctor's note reading "UNDULANT FEVER — REST REQUIRED," calendar showing 1922, open lab notebook with pen in hand, framed 1918 research paper on shelf above. Generate the image immediately without asking clarifying questions.In 1922, Alice Evans contracted brucellosis — the very disease she had spent years warning the public about. She almost certainly became infected through her own research on bacterial samples from raw milk. The illness would recur periodically for the next twenty-three years, causing waves of fever, fatigue, and joint pain that periodically left her bedridden. The fact that she was now personally living with the disease she had identified was not lost on her, or on the scientists who had dismissed her — though many of them still did not acknowledge the irony. Alice recovered enough to return to the laboratory during each remission, and continued her research without stopping.
Panel 8: Allies Emerge¶
Image Prompt
(This is Panel 8 of 12. Do not include the panel number in the image.) Wide 16:9 landscape panel in 1920s–1930s American illustration style — warmer and more hopeful than the previous confrontation panels. Setting: a scientific correspondence scene — Alice Evans's tidy but paper-covered desk at the USDA, circa 1925. She is opening a letter with careful attention, and her expression is shifting from the habitual guardedness of the backlash years to something like cautious relief. The letter, partially visible, is from a European research institution — the letterhead reads "INSTITUTO NACIONAL DE HIGIENE, MADRID" — confirming that Spanish researchers have independently replicated her results with an outbreak of human brucellosis linked to raw goat's milk. On her desk, additional letters are stacked — return addresses from Britain, Denmark, and the Johns Hopkins School of Public Health. A world map on the wall has small red pins marking where her findings have now been independently confirmed. Color palette: warm amber desk light, cream-colored correspondence stationery, the color of hope returning to Alice's face. Mood: the turning of the tide, slow vindication, international science converging on truth. Visual details: letter with European institutional letterhead, world map with red confirmation pins, stack of correspondence from multiple countries, Alice's expression shifting toward relief, wire-rimmed glasses perched on her nose, pile of earlier dismissive letters in a separate darker-colored pile. Generate the image immediately without asking clarifying questions.By the mid-1920s, the walls of resistance were beginning to crack — not because the dairy industry became less powerful, but because science is ultimately self-correcting. Researchers in Britain, Scandinavia, and Spain independently replicated Alice Evans's findings, linking raw milk and goat's milk to human brucellosis outbreaks in their own countries. The Johns Hopkins School of Public Health published confirming studies. Major veterinary research institutions announced that the evidence was sound. One by one, the prominent scientists who had dismissed her began to quietly revise their positions, though few acknowledged they had been wrong. The data had always been correct. It just took the rest of the world time to catch up.
Panel 9: The American Public Health Association Acts¶
Image Prompt
(This is Panel 9 of 12. Do not include the panel number in the image.) Wide 16:9 landscape panel in 1930s government-proceedings illustration style — formal, decisive, historic. Setting: a formal meeting hall of the American Public Health Association, circa 1930. The panel is a wide shot of a large formal chamber with wood-paneled walls and rows of men in dark suits. At the front, a presiding officer stands at a podium while a vote is being called. Alice Evans is seated in the audience, not at the podium — she is not a formal officer, just an observer — but she sits very straight, watching the hands go up. A large banner on the wall reads "APHA — FOR THE HEALTH OF THE PUBLIC." The vote visible on the chairman's tally reads "ENDORSEMENT OF MANDATORY PASTEURIZATION — AYE: 47 — NAY: 3." Alice's expression is unreadable at first glance — but look closely and there is the faintest relaxation in her jaw, the first in years. Color palette: dark formal wood tones, the black of suits and ties, the white of shirts and documents, a single beam of window light falling on Alice in the audience. Mood: the long-awaited vindication in formal bureaucratic language, understated and immensely powerful. Visual details: vote tally board reading 47-3, APHA banner, presiding officer at podium, rows of suited men, Alice in audience with relaxed jaw, gavels and formal papers on the table, tall windows with formal curtains. Generate the image immediately without asking clarifying questions.In the late 1920s and early 1930s, the dam broke. The American Public Health Association formally endorsed mandatory pasteurization of commercial milk. State after state began passing laws requiring that all milk sold for public consumption be heat-treated to kill pathogens. The dairy industry fought the regulations in state legislatures, lobbying fiercely and warning of economic ruin — but the science was now overwhelming, and the public health case was undeniable. Thousands of cases of undulant fever each year, many of them in children, were directly traceable to raw milk. The political momentum, which Alice Evans had helped build through fifteen years of patient evidence-gathering, had become unstoppable.
Panel 10: The States Fall Like Dominoes¶
Image Prompt
(This is Panel 10 of 12. Do not include the panel number in the image.) Wide 16:9 landscape panel in 1930s–1940s American graphic illustration style — bold, map-based, dynamic. Setting: a large illustrated map of the United States, depicted in the bold flat-color style of a 1930s WPA government poster. States that have passed mandatory pasteurization laws are filled in with a warm amber-gold color; states that have not yet passed the law are grey. The map shows amber spreading progressively across the country from the northeast, like a wave of light moving west. In the foreground, a dairy farm is shown in two contrasting halves: on the left, an old-fashioned farm with raw milk being ladled directly into bottles; on the right, a modern dairy facility with gleaming steel pasteurization equipment and workers in white coveralls. Above the map, a small inset portrait of Alice Evans with a subtitle: "Based on research by A.C. Evans, USDA, 1917." Color palette: WPA-poster bold amber-gold, grey, and the steel-blue of modern dairy equipment. Mood: progress, the spread of scientific consensus turned into law. Visual details: US map with amber/grey state fill, raw vs. pasteurized dairy facility contrast, Alice Evans portrait inset, "1917" date label, WPA-style bold graphic design borders, wave of amber spreading from northeast to west. Generate the image immediately without asking clarifying questions.Through the 1930s and into the 1940s, mandatory pasteurization laws spread across the United States, state by state, until pasteurized milk became the overwhelming standard for commercial dairy sales. The practical impact was immediate and measurable: rates of brucellosis, typhoid fever transmitted through milk, and tuberculosis from bovine sources began to fall sharply wherever pasteurization laws took effect. Public health departments could trace the before-and-after data clearly. What had once seemed like one woman's controversial claim was now recognized as one of the most important public health interventions of the twentieth century — saving thousands of lives every year.
Panel 11: First Woman President¶
Image Prompt
(This is Panel 11 of 12. Do not include the panel number in the image.) Wide 16:9 landscape panel in warm 1930s American illustration style — dignified, celebratory without being flamboyant. Setting: the annual meeting of the Society of American Bacteriologists, circa 1928. Alice Evans stands at the podium of a large formal conference room, newly elected as the Society's president — the first woman to hold that position. She is in her mid-40s, still wearing wire-rimmed glasses, her hair neatly waved, dressed in a formal dark suit appropriate to the occasion. The audience — predominantly men in dark suits — applauds, and among them a small cluster of women in the audience applaud with particular intensity. A large banner reads "SOCIETY OF AMERICAN BACTERIOLOGISTS — ANNUAL MEETING 1928." On the podium beside Alice, a small name placard reads "DR. ALICE C. EVANS — PRESIDENT." Behind her, a projection screen shows a graph of declining undulant fever cases correlated with increasing pasteurization. Color palette: warm amber formal hall lighting, dark formal suit colors in audience, the cream-white of Alice's formal papers at the podium. Mood: earned triumph, dignified pride, the formal recognition of scientific leadership. Visual details: president's name placard, Society banner, applauding audience with women's section visible, projected graph of declining disease rates, formal podium with microphone, Alice's dignified posture, wire-rimmed glasses. Generate the image immediately without asking clarifying questions.In 1928, Alice Catherine Evans was elected president of the Society of American Bacteriologists — the first woman ever to lead the organization. The scientific community had finally, officially, recognized her as one of its leaders. The same professional world that had dismissed her for lacking a PhD, for being a woman, for daring to challenge a powerful industry, was now placing her at its head. She used her presidential address not to celebrate her own vindication, but to advocate for more rigorous public health standards and for the importance of connecting laboratory science to real-world policy decisions. It was, characteristically, about the work — not about herself.
Panel 12: A Legacy in Every Glass¶
Image Prompt
(This is Panel 12 of 12. Do not include the panel number in the image.) Wide 16:9 landscape panel — a warm, contemporary memorial-and-legacy scene contrasting with the earlier stark scientific panels. The composition is a triptych. Left third: an elderly Alice Catherine Evans in her 80s or 90s, seated in a comfortable chair by a sunny window, still reading a scientific journal, still wearing her wire-rimmed glasses, expression peaceful. Center third: a modern school cafeteria where dozens of children of diverse backgrounds are drinking cartons of milk with their lunches, entirely safe, entirely unaware of the battle that was fought on their behalf. Right third: a gleaming modern dairy processing facility with stainless steel pasteurization towers, workers in white coveralls, and a quality control panel showing temperature readouts. A faint ghostly image of Alice's 1917 research paper overlays the whole scene. Color palette: warm golden sunlight for the elderly Alice, bright cafeteria colors for the children, clinical steel-blue of the modern dairy facility. Mood: quiet triumph, the vast invisible protection of good science, living legacy. Visual details: elderly Alice with scientific journal, children's milk cartons in cafeteria, modern pasteurization equipment, "1917 Research Paper" ghost overlay, diverse children at lunch tables, quality control readout panel showing safe temperatures. Generate the image immediately without asking clarifying questions.Alice Catherine Evans lived to the age of 94, spending her later decades as a living witness to the transformation she had forced upon American food safety — watching the pasteurization requirement spread from a controversial proposal to an unquestioned public health standard that every parent and every child simply takes for granted. She never quite escaped the occasional recurrence of brucellosis, the disease she had identified, that periodically revisited her body through the end of her life. But she also lived to see thousands of scientific papers confirm her original 1917 findings, to see milk-borne disease rates fall to a tiny fraction of what they had been, and to receive formal recognition from the scientific organizations that had once dismissed her. She died in 1975, in the world she had helped make safer.
Epilogue – What Made Alice Evans Different?¶
Alice Evans's story is a case study in what it means to stay committed to evidence when every social and professional force is arrayed against you. She had no powerful institution behind her, no senior sponsor, no PhD to deflect attacks on her credibility — only her data and her refusal to pretend her data said something different than it did. She endured professional ridicule, physical illness from the very disease she was studying, and decades of industry-funded opposition. Her most important quality was not genius — it was courage. The courage to keep publishing when dismissed, to keep presenting when mocked, and to keep trusting the evidence when industry money was saying otherwise.
| Challenge | How Alice Responded | Lesson for Today |
|---|---|---|
| No PhD — credentials attacked | Let the data speak; continued publishing and presenting | Scientific evidence stands independent of the credential of the person who found it |
| Industry economic opposition | Built an international coalition of confirming research | One study is a finding; twenty studies in six countries is a fact |
| Personal illness from her research subject | Continued working through illness; her own case became additional evidence | Scientists are not separate from their subjects — personal experience can deepen, not compromise, scientific judgment |
| Decades of delay before policy action | Patient accumulation of evidence until the political threshold was crossed | Public health policy change is slow — scientific patience is a professional virtue |
Call to Action¶
The next time you drink a glass of pasteurized milk, a carton of orange juice, or any processed food that carries a safety standard — know that behind that standard is usually a scientist like Alice Evans who saw something dangerous that the industry did not want seen, and refused to look away. Food safety is not automatic. It is won by scientists who are willing to be uncomfortable, dismissed, and ignored — and who publish their results anyway. What does evidence-based science mean to you in a world where powerful interests sometimes prefer different answers?
"Science does not belong to the people who hold the most degrees. It belongs to the people who do the work." —Alice Catherine Evans
"The data were there. I simply refused to stop saying so." —Alice Catherine Evans
