Progress often demands sacrifices, but some scientists have crossed ethical lines by disregarding fundamental human rights for the sake of groundbreaking research. The loss of lives and the trauma inflicted on individuals are often overshadowed by the legacy of the researchers, leaving victims forgotten.
10. Saul Krugman
In 1954, Dr. Saul Krugman initiated research at New York’s Willowbrook State School, a facility for mentally disabled children on Staten Island. As an infectious disease expert, Krugman aimed to study hepatitis transmission and vaccine efficacy. He conducted experiments on 700 children, injecting half with a mild hepatitis strain to observe immune responses and immunity retention, while the other half served as the control group.
Ultimately, the researchers concluded that children intentionally infected with hepatitis exhibited milder symptoms compared to those who contracted it naturally. Krugman and his team defended their experiment by highlighting the widespread hepatitis cases at the facility, arguing that the children were likely to contract the disease regardless. Critics, however, condemned the study for unethical practices, including misleading parents about the risks and failing to obtain fully informed consent.
The researchers faced accusations of coercing parents into enrolling their children in the hepatitis study by claiming no space was available in non-experimental sections of the school. Critics argued that efforts should have focused on addressing the unsanitary conditions causing hepatitis rather than exacerbating the problem through unethical experimentation.
9. Laud Humphreys
Laud Humphreys, a sociologist in the 1960s, focused his research on homosexual encounters in public restrooms, a phenomenon that led to numerous arrests during that era. He sought to understand the motivations behind these impersonal interactions, known as “Tearoom Sex,” and to explore the identities and lives of the men involved outside these clandestine encounters.
To conduct his research, Humphreys positioned himself as a 'watchqueen,' someone who stayed in the room to alert participants of approaching authorities. Under this guise, he gained the trust of many men, persuading them to share personal details without disclosing his true identity or intentions.
For those unwilling to share information, Humphreys took more invasive steps. He tracked them after they left the restroom, noting license plates and addresses. Later, he visited their homes in disguise, posing as a health service interviewer to extract the information they had initially refused to provide. While his research contributed to decriminalizing such acts, it also sparked significant controversy over privacy violations and the exposure of personal information.
8. John Hunter
John Hunter, an 18th-century Scottish figure, is celebrated as a pioneer of modern surgical practices. Despite his scientific contributions, his methods were ethically questionable. Leaving formal education at 13, Hunter spent years dissecting animals during his travels. At 20, he joined his brother William in London, who ran a medical school. John's role was to secure a steady supply of cadavers for anatomical studies and dissections.
Initially, it’s believed Hunter personally exhumed freshly buried bodies from graveyards. However, he soon turned to a more efficient method, forming a lifelong alliance with grave robbers and body-snatchers, a partnership well-documented throughout his career. When these sources failed, Hunter resorted to taking what he needed, such as teeth for his grafting experiments, often without consent.
Composer Joseph Haydn, a close friend of Hunter’s wife, suffered from nasal polyps. After refusing Hunter’s offer to remove them, Haydn was lured to Hunter’s home, where he was forcibly restrained by two men in an operating chair. Haydn narrowly escaped the procedure by convincing Hunter to let him go. Hunter’s life ended in 1793, and his body was dissected by his own students.
7. Ewen Cameron
Dr. Ewen Cameron is infamous for his involvement with the CIA’s MKUltra project, which focused on brain manipulation. Even prior to this, he had a history of disregarding human rights in his experiments. Cameron was particularly interested in memory and developed a controversial technique called depatterning and psychic driving, aimed at erasing a person’s memory and personality to reprogram them with new traits.
One patient, referred to as Mary C, endured 35 days of sensory deprivation followed by 101 days of psychic driving—a process involving the continuous playback of positive affirmations. Other patients were placed in controlled comas and exposed to looped recordings for up to 85 days, drifting between consciousness and unconsciousness. While Cameron succeeded in erasing memories and personalities, he failed to reconstruct them as intended.
Despite criticism from peers, Cameron’s government affiliations allowed him to continue his controversial work. He was even tasked with evaluating Nazi war criminal Rudolph Hess to determine his fitness for trial. Some sources claim Cameron believed the real Hess had already been executed and that he was examining an imposter.
6. Cornell University’s Practice Babies
If your surname is Domecon, it might be worth investigating. This name was assigned to numerous orphaned infants starting in 1919, standing for 'domestic economy.' In one of the strangest academic programs ever, universities like Cornell and the University of Minnesota allowed female students to learn childcare by caring for real babies—orphans temporarily placed in their care.
The babies, aged between three months and a few years, resided in 'practice apartments' designed as training grounds for young women to master household management and childcare. These infants received continuous care, often from as many as 11 or 12 different student mothers during their time in the program. Each student spent six weeks living in the apartment, caring for the baby, before passing the responsibility to the next participant. Although the program ended at Cornell in 1969, some of the now-adult participants have shared how their unstable early upbringing led to lasting trust issues and mental health challenges.
5. Freud And Emma Eckstein
Sigmund Freud has faced significant criticism over the years, particularly for his treatment of Emma Eckstein. Eckstein, one of Freud’s patients, reportedly suffered from irregular and painful menstruation. Freud, convinced of a connection between the nose and genitals, decided the solution was to remove part of her nose.
The procedure not only failed to address her condition but also led to severe complications. Eckstein’s nose wouldn’t heal due to gauze left inside by the surgeon, causing massive bleeding. After a year of recovery, her original issue remained unresolved. Freud concluded that the failure wasn’t due to his theory or the surgeon’s error but rather Eckstein’s alleged 'uncontrollable lust and longing' for him.
Freud defended the surgeon, a close friend, who had performed the botched procedure. He argued that Eckstein’s unresolved issues and the severe bleeding from her damaged nose were not due to surgical error but rather her alleged uncontrollable desire for him. Freud dismissed any fault in his theory or the surgeon’s actions, attributing the complications to Eckstein’s emotions.
4. Muzafer Sherif
Muzafer Sherif, a psychologist in the 1950s, sought to study the escalation of conflict between groups. To observe this firsthand, he organized a camping trip for two groups of 11-year-old boys, deliberately fostering rivalry to see how far tensions would rise.
The 22 boys, unaware they were part of an experiment, traveled to Robbers Cave State Park in Oklahoma. Initially, they bonded within their own groups, the Rattlers and the Eagles. However, when introduced to each other and forced into competitions, the situation deteriorated. What began with name-calling escalated into property damage, food fights, and even disputes over sharing pencils.
After the two groups developed intense animosity, researchers introduced cooperative tasks to reduce hostilities. Over time, the boys began working together, though the experiment left them with a lingering dislike for one another.
3. Lauretta Bender
Lauretta Bender, a neuropsychiatrist at Bellevue Hospital in the 1940s and 1950s, was known for her controversial use of electroshock therapy on children, particularly those diagnosed as autistic. Despite her public claims of success, many children subjected to her treatments became violent or catatonic. As adults, some of her patients faced imprisonment, committed suicide, or were described by their families as irreparably damaged.
Survivors of Bender’s treatments later recounted the horrific conditions at Bellevue, where they were forced to appear cheerful despite enduring brutal procedures. Children were shocked until they seized or lost consciousness, only to be given candy upon waking. Many were misdiagnosed as autistic or schizophrenic, with some later revealing they were merely shy or withdrawn. Bender eventually expanded her methods to include LSD experiments.
2. Eugene Saenger
Dr. Eugene Saenger is a figure of controversy, hailed by some as a hero and condemned by others as a monster. The University of Cincinnati honors him with a scholarship fund, praising his contributions to nuclear medicine. However, his research methods were highly questionable. In the 1960s, Saenger exposed over 90 cancer patients to extreme radiation doses, claiming to explore potential cures and symptom relief.
In reality, the Pentagon sponsored his research to determine the radiation levels that would incapacitate or disorient a person. The subjects were predominantly poor and working-class, with about 60% being Black. Twenty-one patients died within a month of exposure, though Saenger initially claimed only eight deaths were radiation-related and later denied any connection.
Saenger maintained that he informed patients about radiation exposure and even collected consent forms before it was standard practice. However, critics argue he failed to disclose the lethal risks of the experiments.
1. Chester Southam
In the 1960s, Dr. Chester Southam initiated his cancer research by injecting live cancer cells into inmates at the Ohio State Penitentiary. He observed that healthy individuals' immune systems rejected the cells within a month, while cancer patients had a slower response. Southam expanded his experiments by injecting cancer cells into elderly, cancer-free patients at the Jewish Chronic Disease Hospital in Brooklyn.
Southam persuaded hospital administrators that consent forms and patient disclosure were unnecessary. He proceeded to inject 22 chronically ill patients with cancer cells, keeping the experiment secret even from the hospital’s chief of medicine. Ironically, three doctors who rejected his proposal were Holocaust survivors who had lost family members to Nazi atrocities.
