Evelyn Hooker
Psychologist whose research refuted homosexuality as mental illness.
Evelyn Hooker (née Gentry, September 2, 1907 – November 18, 1996) was an American psychologist whose 1956 paper 'The Adjustment of the Male Overt Homosexual' challenged the prevailing classification of homosexuality as a mental disorder. By administering psychological tests to matched groups of homosexual and heterosexual men and finding no detectable difference in mental adjustment, her work provided empirical evidence that helped lead to the removal of homosexuality from the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders.

Lore & Background
Evelyn Hooker was born Evelyn Gentry in North Platte, Nebraska, and grew up in the Colorado Plains. Her mother, Jessie Bethel, who had a third-grade education, urged her to pursue education. Hooker earned a PhD in psychology from Johns Hopkins University in 1932, despite facing gender-based discrimination. After teaching at Whittier College, she contracted tuberculosis and spent a year in a sanatorium. She later received a fellowship to the Berlin Institute of Psychotherapy, where she witnessed the rise of Hitler and Kristallnacht; the Jewish family she lived with was later killed in concentration camps. These experiences sparked her desire to overcome social injustice.
In 1944, while teaching at UCLA, a student named Sam From confided that he was gay and introduced Hooker to his circle of homosexual friends, including writer Christopher Isherwood and poet Stephen Spender. From challenged her to scientifically study homosexuality. Hooker obtained a grant from the National Institute of Mental Health and gathered 30 homosexual men (via the Mattachine Society) and 30 heterosexual men, matched by IQ, age, and education. She administered psychological tests and asked experts to identify the homosexuals and rate their mental health; no detectable difference was found. Her work was published in 1956, just before Sam From died in a car accident.
Reader's Guide
Evelyn Hooker's 1956 study was critical in refuting the then-dominant view that homosexuality was a mental disorder. By using matched samples and blind expert ratings, she demonstrated that homosexual men were as well-adjusted as heterosexual men. She argued that earlier researchers had created a false correlation by studying homosexual men with a history of mental health treatment. Her findings directly challenged cultural heterosexism and the classification of homosexuality as developmentally inferior. Over the following decades, her work gained wider acceptance and was adopted by the gay rights movement. In 1967, the director of the National Institute of Mental Health asked her to produce a report on how the institute should treat homosexual men; the report recommended decriminalization and equal rights. Though its publication was delayed by the Nixon administration, it was eventually published by a magazine in 1970. Hooker's research laid the groundwork for the eventual removal of homosexuality from the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders. She retired from UCLA in 1970 and entered private practice, serving mostly gay and lesbian clients. The University of Chicago opened the Evelyn Hooker Center for Gay and Lesbian Studies in her honor, and she was the subject of the 1992 Academy Award–nominated film Changing Our Minds: The Story of Dr. Evelyn Hooker.

Frequently Asked Questions
Who is Evelyn Hooker?
Evelyn Hooker (née Gentry, 1907–1996) was an American psychologist best known for producing the first major empirical evidence that homosexuality does not constitute a mental disorder. Her landmark 1956 paper is widely regarded as a turning point in clinical psychology and psychiatry.
What did Evelyn Hooker's 1956 study actually find?
She administered standard psychological tests to carefully matched groups of gay and straight men and discovered no measurable difference in their overall mental adjustment. In plain terms, the data showed that being homosexual did not make a person psychologically less healthy.
Why is Evelyn Hooker considered so important in the history of psychology?
Before her work, the prevailing professional consensus treated homosexuality as a pathology, and her study was the first to challenge that view with rigorous empirical data. Her findings became a key piece of evidence that eventually led the American Psychiatric Association to remove homosexuality from its Diagnostic and Statistical Manual.
How did Evelyn Hooker's research change the psychiatric field?
By demonstrating through controlled testing that gay men showed the same level of psychological adjustment as heterosexual men, she undermined the scientific basis for classifying homosexuality as an illness. This shifted the burden of proof and set the stage for the formal declassification of homosexuality as a mental disorder.
When was Evelyn Hooker born and when did she die?
Evelyn Hooker was born on September 2, 1907, and passed away on November 18, 1996, living to see the broader acceptance of the conclusions her research had helped establish.
