When you hear the phrase “10 horrifying facts,” you probably imagine a list of shocking tidbits. In this case, those facts belong to a grim chapter of American history that most people never learn in school: the eugenics movement. Long before the Nazis co‑opted the idea of a “Master Race,” the United States was already experimenting with forced sterilizations, racial purity statutes, and pseudo‑scientific breeding programs. Below we break down the ten most chilling revelations, each backed by primary sources, photographs, and a dash of dark humor to keep you reading.

Why These 10 Horrifying Facts Matter

Understanding this unsettling past is crucial because the remnants of eugenic thinking still echo in modern policy debates, genetic research, and even popular culture. By shining a light on these atrocities, we can better guard against any future attempts to play god with human genetics.

10 What It Was

The American Eugenics Society emerged in the early 1900s, branding itself as a scientific crusade to cleanse the nation’s gene pool. Its agenda went far beyond simple segregation; it advocated for a racially pure, “strong” race untainted by what its members deemed inferior bloodlines—whether that meant race, disability, or socioeconomic status. The society’s most notorious tactic was forced sterilization, targeting individuals labeled unfit to reproduce, such as those with learning disabilities or residents of mental institutions. They also campaigned against interracial marriage and pushed for the sterilization of orphans, the physically disabled, and the so‑called “feeble‑minded.”

The intellectual roots of this movement trace back to Charles Darwin’s theory of natural selection and the work of his cousin Sir Francis Galton. Galton argued that if the most “gifted” members of society married each other, the human race would improve. In a post‑Civil‑War America still wrestling with racial tensions, these ideas proved intoxicating for a self‑appointed elite who believed they could engineer a superior populace.

In 1911, a treatise titled “Preliminary Report of the Committee of the Eugenic Section of the American Breeder’s Association to Study and Report on the Best Practical Means for Cutting Off the Defective Germ‑Plasm in the Human Population” laid out a chilling agenda. The document listed bullet‑point recommendations ranging from forced sterilization to the establishment of euthanasia and gas chambers. Even Supreme Court Justice Oliver Wendell Holmes once remarked, “It is better for all the world… three generations of imbeciles are enough,” encapsulating the callousness of the era.

9 30 States And 60,000 Victims

At the movement’s zenith, thirty American states enacted legislation that legalized the sterilization of individuals deemed genetically unfit. Most of these laws targeted the mentally ill or those labeled mentally deficient, but the net was cast far wider. By the time the programs wound down, an estimated 60,000 people had been forcibly sterilized under state‑sanctioned orders. In states like California, record‑keeping was spotty at best—some files were incomplete, others were altered—making the true tally impossible to pin down.

California’s statutes were particularly draconian. They permitted sterilization of prisoners, individuals suspected of carrying hereditary forms of dementia or insanity, and even minors whose parents consented. Between 1921 and 1950, roughly 450 Californians were sterilized each year, a figure that underscores the sheer scale of the effort. The procedures were applied to men and women of all races, showcasing the movement’s indiscriminate cruelty.

8 Feeble‑Minded, Deaf, And Orphans

The eugenic vision of a perfect American race was not just about intellect; it also demanded a specific physical appearance—tall, blond, blue‑eyed, and “Nordic.” Anything deviating from this ideal was considered a contaminant. While the United States never pursued the genocidal extremes of Nazi Germany, the ideological groundwork was unmistakably similar.

Beyond the mentally ill, the movement targeted the deaf, the sexually deviant, and the so‑called “feeble‑minded.” Alexander Graham Bell, famed for inventing the telephone, was a vocal advocate for silencing the deaf community, even urging that they be barred from marriage. Orphans were especially vulnerable; a mere doctor’s judgment that a child was “unworthy” could result in forced sterilization. One notorious case involved Charlie Follett, who in 1963 was sterilized as a child simply because he was born to alcoholic parents and placed under state care.

7 Supported By Alexander Graham Bell And The Rockefellers

The eugenics crusade attracted an unlikely roster of high‑profile supporters. Alexander Graham Bell, the telephone pioneer, was a staunch proponent who argued that deaf individuals should be prohibited from marrying. Financial backing came from the era’s titans of industry: the Carnegie Institution, the Rockefeller Foundation, and the Harriman railroad conglomerate all funneled money into eugenic projects.

The Carnegies even financed the Cold Spring Harbor research facility, which became a hub for eugenic activity. Meanwhile, the Rockefellers bankrolled a European branch that later employed infamous figures like Josef Mengele. Their contributions extended to organizations such as the German Psychiatric Institute, which helped cultivate the Nazi scientist Ernst Rudin. Even the U.S. Supreme Court upheld eugenic statutes, and Madison Grant, a leading eugenicist, received a fan letter from Adolf Hitler praising his work.

6 The Racial Integrity Act

Virginia’s 1924 Racial Integrity Act was a legal masterpiece of racial control. Its purpose was to document every resident’s race, creating a massive genetic database that could be used to enforce strict marriage regulations. The law mandated that both parties produce certificates proving pure Caucasian ancestry before a marriage license could be issued.

If a registrar doubted the authenticity of the paperwork, they could deny the license outright until both individuals could prove, beyond a shadow of a doubt, that they were “truly white.” Providing false information was classified as a felony, punishable by up to a year in jail. The act effectively turned marriage into a state‑monitored eugenic experiment.

5 Cold Spring Harbor Laboratory

Today, Cold Spring Harbor Laboratory is celebrated for cutting‑edge research in neuroscience, plant biology, and genomics. Yet its origins are steeped in eugenic ambition. Founded in 1910 by Charles Davenport as the Carnegie Institute of Washington, the facility housed the Eugenics Record Office, which meticulously cataloged family histories to trace the inheritance of mental and physical “defects.”

Davenport’s team examined everything from hair and eye color to skin pigmentation, seeking patterns that could supposedly predict traits like hemophilia, schizophrenia, and the nebulous “feeble‑mindedness.” Their archives provided a goldmine of data for eugenicists eager to map and, ultimately, manipulate the human genome.

4 The Immigrant Problem

Eugenicists saw immigration as a biological threat, fearing that newcomers would introduce “undesirable” genes into the American gene pool. Researchers at Cold Spring Harbor even claimed that Italians were predisposed to violence, a baseless stereotype used to justify restrictive policies.

These scientists surveyed prison and mental‑institution populations across the country, correlating criminal or mental illness rates with specific immigrant groups. After outbreaks of smallpox and cholera in New York City and at Ellis Island, eugenicists leveraged public health fears to push for tighter immigration controls. By 1911, they were collaborating with the Immigration Restriction League to influence Congress and the Surgeon General, ultimately shaping the nation’s immigration policy for decades.

3 Better Babies And Fitter Families Contests

State fairs across America turned eugenics into a public spectacle with “Better Babies” contests. Mothers brought their infants to be judged—much like livestock—on health, weight, and overall vigor. While these fairs promoted child‑care awareness, they also reinforced the notion that genetics could be measured and improved.

The concept evolved into “Fitter Families” competitions, where entire families presented their lineage, health records, and physical traits to panels of doctors. Judges awarded points based on a rigid rubric, assigning each family a letter grade that reflected their eugenic “worthiness.” Winners received medals and trophies, and the contests enjoyed massive popularity throughout the 1920s, cementing eugenics as mainstream entertainment.

2 Pioneered By A Stanford Professor

The movement’s intellectual spark came from Stanford professor David Starr Jordan. A devoted student of Charles Darwin and Mendelian genetics, Jordan grew up in western New York before moving to California to teach. At Stanford, he championed eugenic ideals, arguing that America’s upper class was being eroded by the “lower” classes.

Jordan authored several books on eugenics and helped found the Eugenics Committee of the American Breeders Association and the Eugenics Record Office. He believed that careful, selective breeding was essential to preserve the nation’s elite, a viewpoint that fueled the policies and practices that followed.

1 Inspired Hitler’s Master Race

The American eugenics movement didn’t just stay on home soil—it helped lay the groundwork for the Third Reich’s horrific vision of a “Master Race.” A disturbing mutual respect existed between U.S. eugenicists and Nazi officials. In 1937, the American Eugenics Society publicly praised Nazi sterilization programs, claiming they achieved the scale of extermination Americans had only imagined.

Eugenic writings from the U.S. advocated for everything from gas chambers to abandoning “inferior” populations to disease or the elements. While America never embraced the full brutality of the Nazi regime, its scientific literature and policy experiments provided a template that Hitler eagerly copied. Adolf Hitler even quoted American eugenic texts to legitimize his own murderous agenda, underscoring how deeply intertwined the two movements were.

10 widely admired individuals have left indelible marks on history, yet many of them harbored disturbing beliefs about eugenics. While Adolf Hitler is rightfully condemned for turning eugenics into a murderous ideology, a surprising roster of celebrated personalities also endorsed the notion of cleansing society of those they deemed “undesirable.” Most stopped short of advocating gas chambers, but their recommendations were far from humane.

1 Clarence Darrow

The eloquent defense attorney Clarence Darrow was famous for his poetic pleas for compassion, urging society to abandon hatred and cruelty. He declared, “I am pleading for the future… when all life is worth saving and mercy is the highest attribute of man.” By the early 1900s, Darrow had earned the nickname “Attorney for the Damned,” a nod to his reputation as a champion of society’s outcasts.

Darrow’s most controversial moment came during the infamous Leopold‑Loeb case. He argued that the murder of 14‑year‑old Bobby Franks was not driven by personal animus but by the defendants’ privileged upbringing, wealth, and fascination with detective novels. In a 1926 piece for The American Mercury, Darrow vehemently opposed sterilization and bans on intermarriage, insisting that “morons, idiots, and imbeciles” were essential for manual labor.

Paradoxically, Darrow also endorsed a cold mercy for disabled infants. He echoed surgeon Harry Haiselden’s sentiment, stating, “Chloroform unfit children… Show them the same mercy that is shown beasts that are no longer fit to live.” This contradictory stance highlights the complexity of his legacy.

2 Woodrow Wilson

For more than half a century, Woodrow Wilson has been celebrated as one of America’s top ten presidents. Franklin D. Roosevelt once praised him, saying, “All our great presidents were leaders of thought at times when certain ideas in the life of the nation had to be clarified.” Wilson’s leadership during World War I earned him a Nobel Peace Prize for negotiating the Treaty of Versailles and championing the League of Nations.

Domestically, Wilson spearheaded the creation of the Federal Trade Commission and the Federal Reserve, advanced child‑labor reforms, and supported women’s suffrage. He famously asserted, “I do not believe that any man can lead who does not act… under the impulse of a profound sympathy with those whom he leads.” Yet, as governor of New Jersey in 1911, Wilson signed a sterilization bill that mandated the forced sterilization of “feeble‑minded” individuals, epileptics, rapists, certain criminals, and other “defectives,” citing heredity as the primary cause of these conditions.

Wilson’s own health declined dramatically after a massive stroke in 1919, leaving him partially paralyzed and visually impaired for 17 months. His wife and physician concealed his condition, leading some historians to refer to her as the nation’s first female president. One wonders whether Wilson himself would have been a target of the very eugenic policies he helped enact.

3 William Edward Burghardt Du Bois

W.E.B. Du Bois, a towering intellect in African‑American history, often clashed with other black leaders yet left an indelible mark on civil‑rights activism. Born in 1868, he earned the first African‑American doctorate in history from Harvard and soon after began publishing groundbreaking studies on black life in the United States.

Du Bois co‑founded the NAACP and edited its influential magazine, The Crisis. However, his vision of racial uplift diverged sharply from the NAACP’s integrationist stance. He advocated for a form of eugenics within the black community, dividing it into the “Talented Tenth” – educated leaders – and the “submerged tenth,” which he described as criminals, prostitutes, and loafers. In the Birth Control Review, he warned that “the mass of ignorant Negroes still breed carelessly and disastrously,” urging the promotion of marriage and reproduction among the “Talented Tenth” while discouraging it among the “submerged tenth.”

Du Bois’s eugenic ideas were rooted in a belief that the “best” Black individuals should reproduce, thereby improving the race, while the “undesirable” should be curtailed. This stance starkly contrasted with his broader fight for equality, revealing a troubling paradox in his legacy.

4 Edward Franklin Frazier

Edward Franklin Frazier rose to prominence as the pre‑eminent African‑American sociologist of the early twentieth century, eventually chairing Howard University’s sociology department. He argued that Black Americans had become culturally American, shedding their African heritage, and criticized middle‑class Black individuals for materialism and cultural elitism.

Although Frazier rejected the white‑centric Nordic eugenics model, he adopted a class‑ and geography‑based eugenic framework for Black Americans. In his work Eugenics and the Race Problem, he warned that “colored feebleminded” individuals in the South were breeding unchecked, while “colored feebleminded” in the North received less scrutiny. He contended that the “best mentally endowed Negroes” would not dilute their inheritance by intermarrying with the feebleminded, suggesting institutional controls were necessary to curb the reproduction of the latter.

Frazier’s perspective framed the North as a meritocratic environment where natural selection favored the “brightest” Black individuals, whereas the South was depicted as a breeding ground for “undesirable” traits. His rhetoric mirrors classic eugenic language, emphasizing control over reproduction to “improve” the race.

5 John Maynard Keynes

John Maynard Keynes emerged in the early 1900s as one of the world’s leading economists, reshaping macroeconomic thought with his seminal work The General Theory of Employment, Interest and Money. His ideas championed government deficits during economic downturns to sustain employment, a radical departure from the era’s prevailing balanced‑budget orthodoxy.

Keynes’s theories guided President Franklin D. Roosevelt’s New Deal policies, which aimed to revive the American economy during the Great Depression. While some scholars debate the efficacy of those measures, Keynes’s influence persisted in U.S. fiscal policy until the 1980s, when Reagan’s monetarist approach took hold.

Beyond economics, Keynes was an avid eugenicist. In The Essential Keynes, he argued that nations must devise policies concerning not only population size but also “innate quality.” As director of the Eugenics Society for seven years, he advocated for contraception to curb the growth of “drunken and ignorant” lower‑class populations, whom he deemed incapable of self‑regulation.

6 Oliver Wendell Holmes Jr.

Oliver Wendell Holmes Jr., an associate justice of the U.S. Supreme Court for three decades, remains celebrated as one of America’s most brilliant jurists. Appointed by Theodore Roosevelt in 1902, he earned the moniker “The Great Dissenter” for his incisive dissenting opinions that continue to shape legal thought.

Holmes’s legacy, however, is tainted by his 1927 majority opinion in Buck v. Bell, which upheld Virginia’s forced‑sterilization law. The case involved Carrie Buck, a young woman labeled “feeble‑minded” after an unwed pregnancy. Holmes argued that sterilizing her would protect “society and her welfare,” famously declaring, “Three generations of imbeciles are enough.” This decision provided legal cover for thousands of forced sterilizations across the United States.

Internationally, the Nazis seized upon Holmes’s language to justify their own atrocities, citing his opinion as evidence that “the world” could prevent the propagation of “degenerate” offspring. Holmes’s influence thus extended far beyond the courtroom, leaving a chilling imprint on eugenic policy worldwide.

7 Linus Pauling

Linus Pauling, a double Nobel laureate in Chemistry and Peace, is revered for his scientific brilliance and tireless advocacy against nuclear weapons testing. His discovery that sickle‑cell anemia stemmed from a single genetic mutation marked the first identification of a “molecular disease.”

Pauling soon intertwined his scientific insights with eugenic thinking. He argued that to alleviate human suffering, societies should legally mandate testing for genetic diseases such as sickle‑cell anemia, especially among African‑American populations. He proposed restricting marriage and reproduction for carriers, suggesting that the state intervene to prevent the transmission of hereditary ailments.

Later, Pauling advocated even more extreme measures: tattooing or otherwise marking carriers on their bodies—potentially on the forehead—to signal their status and discourage intermarriage. He also supported abortion for pregnancies involving two carriers, asserting that ending such lives would spare future suffering. Notably, Pauling stopped short of endorsing forced sterilization or the killing of already‑born children.

8 Sir Winston Churchill

In 2002, Sir Winston Churchill was voted the greatest Briton of all time, celebrated for his steadfast leadership during World War II and his literary achievements, including a Nobel Prize in Literature. He famously warned that “the unnatural and increasingly rapid growth of the feeble‑minded and insane classes” posed a grave national danger.

Churchill’s correspondence with Prime Minister Herbert Asquith in 1910 revealed his belief that preserving a “superior” race required curbing the reproduction of “feeble‑minded” individuals. The 1913 Mental Deficiency Act, which he supported, defined categories such as “idiots,” “imbeciles,” “feeble‑minded,” and “moral defectives,” authorizing their indefinite confinement and, in some cases, sterilization.

While Churchill never advocated the use of gas chambers, he endorsed segregation, confinement, and sterilization of those he deemed “inferior.” His eugenic stance, juxtaposed with his wartime heroics, underscores a paradoxical aspect of his legacy.

9 Theodore Roosevelt

Theodore Roosevelt, the beloved “trust‑buster” president, remains a towering figure in American history. He championed the Square Deal, spearheaded conservation efforts that birthed the U.S. Forest Service and the National Wildlife Refuge System, and earned the Nobel Peace Prize in 1906.

Roosevelt also famously inspired the teddy bear after refusing to shoot a bound bear, deeming such an act unsportsmanlike. Yet, his views on eugenics were far less compassionate. In a January 3, 1913 letter to Charles Davenport of the Eugenics Record Office, he likened human reproduction to livestock breeding, insisting that society should prevent “degenerates” from reproducing. He argued that just as farmers apply selective breeding to improve stock, citizens must leave only “good blood” behind.

Ironically, despite promoting an image of robust physical vigor, Roosevelt suffered from severe asthma, myopia, heart issues, blindness in one eye from a boxing match, and hearing loss in one ear—all ailments he nonetheless dismissed in his public persona.

10 Helen Keller

Helen Keller, famed for overcoming blindness and deafness after a childhood illness, became an iconic advocate for the blind and deaf. With the unwavering support of her teacher Anne Sullivan, Keller avoided institutionalization and went on to champion women’s rights, birth control, the NAACP, and co‑found the ACLU. Her legacy lives on through the Helen Keller Services for the Blind, which empowers individuals with disabilities to secure education and employment.

Beyond her activism, Keller harbored eugenic convictions concerning mental disabilities. In 1915, surgeon Harry Haiselden refused to operate on infant John Bollinger, labeling the child “defective” and urging the parents to let him die, claiming he would become an “idiot” and potential criminal. Keller echoed Haiselden’s stance in a letter to The New Republic, arguing that cases of severe mental deformity should be judged by a “jury of expert physicians” rather than lay juries, asserting that such individuals would never become productive members of society and posed a criminal risk.

Keller’s correspondence framed the debate as a clash between “fine humanity” represented by physicians and “cowardly sentimentalism” of the public. Her endorsement of eugenic policies illustrates a lesser‑known, unsettling facet of her remarkable life.

10 Widely Admired Figures and Their Eugenics Views

The ten individuals highlighted above demonstrate that admiration for public achievements does not preclude the endorsement of troubling ideologies. Their eugenic beliefs, ranging from support for forced sterilization to advocating selective marriage policies, reveal a complex tapestry of historical attitudes that continue to inform contemporary discussions about ethics, science, and social policy.
