History of Conversion Therapy: Pioneers, Laws, and Change

Historical context: how conversion therapy ideas formed

No single person “invented” conversion therapy. The goal grew from old beliefs that same-sex desire was a harm. Clinicians then tried many ways to change it. Each era had its own ideas and tools.

In the history of conversion therapy, people often cite three phases. First came early psychoanalysis and related mind theories. Next came broad medical use in clinics and hospitals. Later, after Stonewall, activists and researchers pushed back.

This shift changed what “therapy” meant in real life. Early views treated homosexuality as a defect to fix. Later views treated it as a normal part of life. That change shaped rules, ethics, and laws.

Conversion therapy pioneers used the best science they had. They shared one core assumption. Sexual orientation could be changed like a symptom. That is the key thread across time.

Key figures who shaped early conversion theories

Richard von Krafft-Ebing helped shape early ideas in the late 1800s. His work put same-sex desire into medical talk. It also tied the idea to harm and cure hopes. Those frames influenced later writers and doctors.

Eugen Steinach pushed a more extreme plan. He proposed physical changes to shift sexual behavior. This fit his era’s view that bodies could be “reworked.” People then tried to link love to organs and glands.

These men did not work alone. Their ideas fit a wider mood in medicine. Many fields labeled traits as illness. Homosexuality often fell under that net.

• Krafft-Ebing helped bring homosexuality into medical writing.
• Steinach suggested body changes to alter sexual behavior.
• Later clinicians borrowed these links to justify “cures.”

That is why the “who invented conversion therapy” question is hard. The practice grew through many links, not one breakthrough.

Psychoanalysis and conversion therapy: where theory met clinical practice

Many people connect psychoanalysis and conversion therapy because Freud shaped mind talk in clinics. Sigmund Freud was a major figure in mind theory. His ideas shaped how some doctors saw desire and choice.

Freud did not claim an easy cure for sexual orientation. He saw it as complex and hard to shift. He also noted most change attempts were unlikely to work. That is an important nuance.

Even so, Freud’s name still comes up in this debate. Some accounts link his ideas to hypnosis. Hypnosis is a trance-like state for focused focus. Some clinicians tried it as a path to change thoughts.

Still, theory and practice do not match perfectly. A therapist can use any tool with the wrong goal. If a clinic aims to “fix” a person, harm can follow. Many accounts describe shame and fear from that aim.

Time view	How it framed same-sex desire	Common “treatment” angle
Early mind theories	Often as hidden inner conflict	Talk plus suggestive methods
Medical mainstream	Often as a sickness	Structured clinic programs
Post-Stonewall shift	Asked as bias and harm	Support without change pressure

Once the goal changes, the ethics change too. Support can reduce stress without forcing change.

Legal and social reactions: from medical dominance to rights-based bans

After Stonewall, public debate grew louder. Many LGBTQ groups said this work caused real harm. They argued it pushed stigma instead of help. They also said the “cure” claim lacked strong proof.

At the same time, mental health ethics grew stricter. Informed consent became a major standard. Coercion and shame became harder to defend in care.

As views shifted, lawmakers moved too. Legislation against conversion therapy started to spread. Many bans used a human rights frame. They also focused on child safety and fair access to care.

Europe showed this trend in clear ways. Rules grew from the idea that sexual orientation is not a flaw. Where laws changed, clinics faced new limits. That is what policy can do when views catch up.

• Activists pointed to harm and stigma.
• Researchers challenged the cure claim.
• Lawmakers treated it as bias, not care.

When society drops the pathology view, the “conversion” goal loses power.

Current views and bans on conversion therapy today

Today, most mental health groups reject conversion therapy. They cite harm risk and weak proof of success. Many also say it can raise anxiety and low mood. It can also harm trust in care.

European legal frameworks have also shifted. Germany has passed laws to curb the practice. Malta has also banned it. These moves reflect changing public views on sexual orientation and care ethics.

Bans can differ by scope. Some laws target work with minors first. Others cover any offer that aims at change. Some also restrict how services are sold to the public.

Even with bans, people still seek support. The best “psychological treatment” goals tend to be wellbeing. Therapists often help with stress, family strain, and fear. They do not try to erase identity.

If you are choosing care, ask a direct question. Ask what the goal of therapy is. Then check that the goal matches the person’s wellbeing. No one should face pressure to “perform” change.

Future perspectives: where sexual orientation treatments may go next

Future work will likely focus on two aims. First is evidence for what helps mood and function. Second is human rights and care ethics.

Clinics may also offer more joined support. Support can cover both gender identity and sexual orientation stress. But the aim should stay the same. Reduce distress, improve coping, and keep dignity.

Researchers are likely to study better outcomes next. They can track stress levels, sleep, and daily function. They can also study the role of bias and family risk. Those steps fit a care model that respects people.

So what comes after bans? Training may be the next big step. Clinicians can learn stigma care and safe talk. Schools can also learn how to support youth without shame.

When a field stops calling a trait a sickness, “conversion” loses its base.

Quick timeline recap of conversion therapy history

Here is a clear outline of key moments. Use it to place each figure in the right era. It also answers “who invented conversion therapy” in a fair way. It was a chain, not one invention.

1. Late 1800s: Krafft-Ebing links same-sex desire to medical talk and cure hopes.
2. Early 1900s: Steinach argues for body change to shift sexual behavior.
3. Mind theory era: Freud’s mind ideas guide some talk methods, with hypnosis mention.
4. Post-Stonewall era: Activists and science reject the cure idea as harm.
5. Recent decades: Many places ban the practice under rights rules.

That is why the phrase “conversion therapy pioneers” makes sense. Each period had its own leaders. The common link was the desire to change sexual orientation.
