Here’s an uncomfortable piece of history that tends to get shoved into the nation’s “miscellaneous” drawer (right next to landline
chargers and that one sock nobody remembers buying): long before Nazi Germany turned eugenics into a state-engineered horror show,
the United States had already helped popularize eugenic ideas, built institutions around them, and passed laws that targeted people
deemed “unfit” for reproduction.

If you’re thinking, “Waitwasn’t eugenics a Nazi thing?” that’s a very common assumption. But eugenics was a transatlantic movement,
and American eugenicists were influential in shaping early 20th-century policy debates about immigration, disability, poverty,
criminality, and public health. The fact that it was once considered “modern” and “scientific” is exactly what makes it such a
cautionary tale todaybecause the science was flimsy, the morality was nonexistent, and the consequences landed on real human bodies.
In plain English: it was bad data wearing a lab coat and pretending to be destiny.

What Eugenics Claimed to Be vs. What It Actually Was

The sales pitch

Eugenics was marketed as a way to “improve” the human population by encouraging reproduction among the “fit” and discouraging or
preventing it among the “unfit.” The theory leaned on a simplistic (and incorrect) interpretation of hereditytreating complex traits
like intelligence, morality, and “social usefulness” as if they were inherited like eye color. Modern genomics and public health
organizations have repeatedly emphasized how scientifically inaccurate and socially dangerous these ideas were. The “unfit” label was
often a cocktail of bias: disability stigma, racism, sexism, class prejudice, and fear of immigrants. Eugenics didn’t discover a
problemit invented one, then appointed itself as the solution.

The reality

In practice, eugenics became a policy toolbox for controlling reproduction. It encouraged segregation and institutionalization,
restricted marriage, influenced immigration restrictions, andmost infamouslyhelped justify coerced or involuntary sterilization.
These policies were frequently aimed at people with disabilities, people living in poverty, women who didn’t conform to social norms,
and communities already marginalized by law and custom.

How the U.S. Built an Eugenics Infrastructure

From “idea” to institution

One reason American eugenics became so influential was that it didn’t remain a fringe opinion. It developed a professional network:
researchers, conferences, popular books, public exhibits, and organizations that presented eugenics as mainstream science. A key hub
was the Eugenics Record Office (ERO), founded in 1910 at Cold Spring Harbor, with Charles Davenport playing a major role and Harry H.
Laughlin appointed as director. The ERO promoted eugenic ideas widely and advocated for policies like sterilization of “defectives”
and restrictions on immigration. When a movement has a filing system, letterhead, and lobbying strategy, it tends to get taken more
seriously than it deserves.

“Progress,” with an asterisk the size of a billboard

The early 20th century “Progressive Era” is often remembered for reformsworkplace safety, sanitation, child labor limits. But it also
produced a climate where experts and institutions were trusted to engineer social outcomes. Eugenics slid into that space by
presenting social problems as biological defects. If poverty is “hereditary,” then you don’t have to fix wages. If crime is “in the
blood,” then you don’t have to fix schools. The logic is convenientand cruelty is always more efficient when it’s dressed as
“prevention.”

America’s Eugenic Laws: Sterilization as Government Policy

Indiana goes first

In 1907, Indiana approved what is widely recognized as the first state law in the U.S. mandating sterilization for certain people in
state custody, based on eugenic assumptions. That law didn’t stay isolated. It became part of a broader legislative trend as other
states followed with their own sterilization statutes.

Buck v. Bell: when the Supreme Court stamped it “approved”

The turning point for legitimizing these policies nationally came in 1927 with Buck v. Bell. The U.S. Supreme Court upheld a
Virginia law permitting compulsory sterilization, and Justice Oliver Wendell Holmes Jr. wrote the infamous line:
“Three generations of imbeciles are enough.” That sentence didn’t just echo through legal historyit echoed through hospitals,
institutions, and state programs. It gave a constitutional-looking veneer to a policy that treated people’s reproductive capacity as
public property.

Importantly, Buck v. Bell did not come from a neutral search for truth. The case involved Carrie Buck, a young woman labeled
“feebleminded” in an era when such labels could be pinned on someone for being poor, sexually assaulted, or simply inconvenient to
powerful institutions. The legal and medical system around her treated her life as evidence that the state needed “protection” from
her future childrenan idea as chilling as it is illogical.

How big was it?

Across the 20th century, tens of thousands of Americans were sterilized under eugenic laws. A commonly cited estimate is that more
than 60,000 people were forcibly sterilized in the United States through these programs. California ran the largest state program,
with roughly 20,000 procedures under its eugenics law era, which spanned much of the 20th century and was not repealed until 1979.
Numbers are not the whole storybut they do show scale. And scale turns “bad ideas” into a national harm.

California: The Epicenter of American Eugenic Sterilization

Why California mattered

California’s program is often highlighted because it was extensive and influential. The state passed a eugenics sterilization law in
1909 and carried out sterilizations in state institutions for decades. Historical analyses and public policy discussions have pointed
out that California’s program was widely regarded as “successful” by eugenicists of the erameaning it was efficient at violating
human rights. The victims included people labeled as “feebleminded,” people with disabilities, women deemed sexually “immoral,” and
communities targeted through racial and social bias.

It didn’t stop neatly when the world learned better

Eugenics lost public legitimacy after the Nazi regime exposed what the “logic” of racial hierarchy could become. But U.S. programs did
not simply vanish overnight. Many continued well into the mid-20th century, and some abuses involving coerced sterilization appeared
even later, including controversies involving prisons and detention settings. In other words: the movement’s branding died faster than
the underlying behavior.

Immigration Restriction: Eugenics at the Border

The 1924 law and “scientific” nativism

Eugenic thinking did not stay confined to hospitals or institutions. It also shaped federal immigration policy. The Immigration Act of
1924 (often called the Johnson-Reed Act) created restrictive quotas and helped build a visa regime designed to limit immigration from
regions considered undesirable by lawmakers and influential advocates. Histories of this era show how eugenics was embraced by
respected professionals and treated as cutting-edge “science” that could justify who should be allowed into the countryand who should
be kept out.

When policymakers treat a nation like a “breeding program,” immigration becomes less about opportunity and more about “stock.” That
framework is dehumanizing by design. It also shows how eugenics was never just one policy; it was a worldviewone that tried to
reorganize society around a fantasy of inherited worth.

So…Did American Eugenics Influence Nazi Policy?

The short version (without the softening)

Nazi Germany did not need permission to be brutal. But historians and archival institutions have documented connections between
American eugenic policy ideas and the Nazi regime’s early sterilization framework. For example, Germany passed a 1933 sterilization law
(“Law for the Prevention of Offspring with Hereditary Diseases”) mandating forced sterilization of people with certain conditions.
Scholarly and archival summaries note that Harry Laughlin’s “model” sterilization law and his work were known internationally, and
accounts of his connections with Germany have been documented. Some sources describe Germany’s 1933 law as loosely structured on
Laughlin’s model.

Important nuance: influence is not the same as responsibility

Saying “American eugenics influenced Nazi policy” doesn’t mean the U.S. caused Nazism. But it does mean American laws and institutions
helped normalize the idea that the state could classify people by worth and control reproduction accordingly. That normalizationthis
“it’s for public health” languagecreated a vocabulary and a sense of legitimacy that traveled. And once a government believes it can
sterilize the “unfit,” the distance to further atrocities becomes terrifyingly short.

How “Respectable” Eugenics Becameand Why That’s the Scariest Part

Bad science thrives when it flatters power

Eugenics spread because it told influential people what they wanted to hear: that their success was inherited, their status was
deserved, and social inequality was naturenot policy. When an idea says, “The system is fine; it’s the people who are defective,”
it doesn’t just survive. It gets funded.

Labels that swallowed lives

Terms like “feebleminded” functioned as a policy weapon. They were vague, elastic, and often applied to people who were poor, disabled,
or socially nonconforming. Women and girls were especially vulnerable because sexuality itself could be treated as evidence of “unfit”
character. Institutional settings amplified the risk: if you were already in the custody of the state, it was easier for the state to
decide your future.

After the Fall of Eugenics, the Damage Stayed

Apologies, archives, and late justice

In recent decades, more states and institutions have confronted this history through apologies, historical markers, museum exhibits,
and academic research. Some states created compensation programs for survivors. California, for instance, launched a reparations effort
in the 2020s aimed at identifying and compensating people sterilized under its eugenics laws, as well as some later victims sterilized
in incarceration contexts without proper consent.

These efforts face real obstacles: records are missing, survivors are elderly, and the legal system that once enabled the harm rarely
offers a clean path to repair. But public acknowledgment mattersnot as a substitute for accountability, but as a refusal to pretend it
never happened.

What This History Still Teaches Us

1) “Science” can be misused as a shortcut to prejudice

Eugenics shows what happens when scientific language is used to declare a social hierarchy “natural.” It becomes harder to argue with
not because it’s right, but because it sounds technical. A spreadsheet can’t be racist, right? Wrong. A spreadsheet can be racist in
twelve columns and a pivot table.

2) Reproductive control is a recurring tool of oppression

The eugenics era reminds us that controlling who can have childrenand under what conditionshas often been used against marginalized
communities. That’s why modern discussions about informed consent, disability rights, medical ethics, and reproductive justice keep
returning to this history. It’s not ancient. It’s a warning label.

3) Courts can be a megaphone for injustice

Buck v. Bell demonstrates that legal approval does not equal moral legitimacy. When the Supreme Court blesses a policy, that
policy can expand dramatically, even if it violates basic human dignity. Constitutional language can be used to protect rightsor to
rationalize their removal.

Experiences and “Lived Echoes” of Confronting American Eugenics

History like this doesn’t just live in textbooksit shows up in the experiences of people who encounter it through family stories,
community memory, medical systems, and public records. Many descendants of those targeted by sterilization programs describe a kind of
quiet shock that arrives late: a grandparent who never talked about why there were no siblings, a relative whose medical “procedure”
was described with euphemisms, or a family tree that looks less like an accident of fate and more like a decision made by the state.
When someone realizes a missing branch wasn’t naturalwasn’t illness or chancebut policy, the grief can feel uniquely disorienting.

Students and researchers who work with archives often describe an emotional whiplash: the documents can read bland, bureaucratic, even
“helpful,” while describing something devastating. A file might include tidy categories, checkboxes, and clinical languageyet behind
that language is the irreversible loss of reproductive choice. It’s a strange experience to see cruelty organized like office work.
People sometimes expect the past to look obviously villainous, but eugenics paperwork can look painfully ordinarylike the harm wore a
cardigan and used good penmanship.

Survivors and advocates frequently describe another experience: the exhausting work of being believed. Because eugenics was framed as
medicine and public welfare, victims were often treated as unreliable narrators of their own lives. Some were told the procedure was
for their “health,” their “release,” or their “future,” and later discovered what it truly meant. Even when governments acknowledge
wrongdoing decades later, survivors may still face barriers: missing documentation, complicated eligibility rules, and the emotional
burden of reliving trauma to prove it happened. Reparations efforts can bring validation, but they can also reopen woundsespecially
when the process feels like yet another system demanding compliance.

Communities that were disproportionately targeted can experience this history as part of a broader pattern: medical mistrust is not
paranoia when your history includes institutions that treated your body as a social problem to manage. That mistrust can show up in
everyday healthcare experiencesextra questions before signing a consent form, wariness about “routine” procedures, and a heightened
sensitivity to being labeled or dismissed. These reactions aren’t irrational; they’re learned survival strategies passed down through
stories, warnings, and lived examples.

And there is another kind of experience, too: the moment people realize eugenics isn’t just a “Nazi chapter” but an American one.
Visitors to museums, readers of court opinions, or listeners to podcasts on the topic often describe a sudden mental rewiring. The
narrative changes from “that happened over there” to “that happened here,” and the emotional tone shifts from distant condemnation to
personal responsibility. It can be uncomfortablebecause it forces a harder question than “How could they?” It asks, “What did our
institutions do, what did our culture permit, and what do we still risk repeating when we treat human value as measurable and
inheritable?”

Confronting American eugenics can feel like standing in front of a cracked mirror: you recognize the outline of modern debatesabout
disability, poverty, immigration, and “deservingness”but you see how quickly those debates can be warped into policies that violate
human rights. The experience is sobering. But it can also be clarifying. It reminds us that ethics isn’t automatic, science isn’t
self-correcting without accountability, and “progress” is only progress if it includes everyone.

Conclusion

The fact that American eugenics preceded Nazi eugenics isn’t triviait’s a warning about how quickly a society can turn prejudice into
policy when it is labeled “science.” The United States didn’t invent cruelty, but it did help build a modern bureaucratic model for
managing reproduction through law, institutions, and courts. Remembering that history is not about shame for its own sake. It’s about
recognizing patternsso we can refuse them in the present.
