The Dark History of Lobotomy: How a Brutal Surgery Won a Nobel Prize

A Surgery That Should Never Have Existed

Between roughly 1935 and 1970, somewhere between 40,000 and 50,000 people in the United States alone had lobotomies performed on them. In the UK the number was around 17,000. Globally, the total ran into the hundreds of thousands. These were not desperate last-resort procedures performed quietly and with shame. The prefrontal lobotomy was celebrated, promoted aggressively by its champions, and rewarded with the highest honor in medicine.

The man most responsible for its spread in America, Walter Freeman, performed lobotomies as a kind of traveling show, driving a van he called the "lobotomobile" from state hospital to state hospital, demonstrating his technique to doctors who had no surgical training. He operated on hundreds of patients in a single year, sometimes doing multiple in a single day. His youngest patient was twelve years old.

Where It Started: Moniz and the Nobel Prize

The prefrontal lobotomy was invented by a Portuguese neurologist named Antonio Egas Moniz in the 1930s. The procedure severed the connections between the prefrontal cortex and the rest of the brain. Moniz's theory, based largely on animal experiments by American researchers John Fulton and Carlyle Jacobsen, was that cutting these connections would relieve the anxiety and obsessive thinking seen in severe psychiatric illness.

The animal research Moniz drew on showed that chimpanzees with damaged frontal lobes became calmer and less agitated when confronted with stressful tasks. Moniz extrapolated from chimpanzees to human patients with a speed and confidence that later struck critics as reckless. He performed his first procedure in 1935 and published results the following year claiming success.

His initial technique involved injecting alcohol to destroy tissue in the frontal lobes. He later moved to a tool called a leucotome, a thin instrument with a wire loop that could be rotated to core out sections of brain tissue. In 1949, Moniz received the Nobel Prize in Physiology or Medicine for "the discovery of the therapeutic value of leucotomy in certain psychoses." It remains one of the most controversial Nobel awards in history, and there have been intermittent campaigns to revoke it posthumously, so far without success.

Walter Freeman and the Ice Pick

Walter Freeman was an American neurologist who became Moniz's most enthusiastic promoter. He initially performed the standard procedure with his surgical partner James Watts, but what he really wanted was something faster, cheaper, and scalable to the massive overcrowded state mental hospitals across America.

The transorbital lobotomy, which Freeman developed, achieved exactly that. The patient was rendered unconscious with electroconvulsive shock (Freeman had no anesthesia training and was not permitted to administer chemical anesthesia). Freeman then inserted an instrument resembling an ice pick through the thin bone above the eye socket, into the space behind the eyeball, and into the frontal lobe. He moved the instrument back and forth to sever connections, then repeated on the other side. The whole procedure took ten minutes.

Freeman was not a surgeon. His partner Watts, who was, eventually refused to participate and the two parted ways. Freeman continued operating alone. He didn't scrub in, didn't wear gloves in early demonstrations, and treated the procedure with a briskness that horrified conventionally trained physicians. He once performed 25 transorbital lobotomies in a single day.

Who Got Lobotomized

The patient population was not limited to people with the most severe and intractable psychiatric conditions. As the procedure spread and its implementation became faster and cheaper, the criteria for recommending it expanded dramatically.

State mental hospitals were catastrophically overcrowded. The economics of the situation pushed administrators toward any procedure that might discharge patients or at least make them easier to manage. A lobotomized patient who sat quietly in a chair was a quieter ward. That was often the actual goal.

Women received lobotomies at higher rates than men. Many patients were institutionalized for what we would now recognize as depression, anxiety, postpartum illness, or nonconformist behavior. Some were homosexual men whose families or doctors considered their sexuality a form of mental illness requiring treatment. Children and teenagers were operated on. The elderly were operated on. Patients who had simply not responded to other treatments, or whose families found them difficult, were operated on.

Rosemary Kennedy, sister of President John F. Kennedy, received a lobotomy in 1941 at age 23. She had been described as mildly intellectually disabled and prone to mood swings and disobedience. After the operation, she was left permanently incapacitated, unable to walk or speak coherently, and was institutionalized for the rest of her life. Her father Joseph Kennedy had authorized the surgery without fully informing the rest of the family.

The Results

What did lobotomy actually do to patients? The honest answer is that the outcomes varied enormously and the reporting by early proponents was selective and unreliable. Freeman's own follow-up was inconsistent and optimistic in a way that later analysis found difficult to justify.

Some patients did become calmer and more manageable. But the mechanism was not therapeutic in any meaningful sense: it was damage. The frontal lobes are central to personality, planning, judgment, emotional regulation, and the capacity for complex thought. Severing their connections produced not healing but deficit.

Common outcomes included flattening of personality, loss of initiative, impaired judgment, incontinence, seizures, and in some cases death. Freeman's own records show a mortality rate of around two to three percent from the procedure itself, which across the tens of thousands of operations he performed represents a significant number of deaths. Death rates at some hospitals were higher.

Critics during the period, including many psychiatrists and neurologists, raised these objections loudly. The problem was that the alternative, leaving severely ill patients in overcrowded and brutal state hospitals with almost no effective treatments available, was also genuinely terrible. Lobotomy's proponents argued, with some justice, that they were offering something when nothing else worked. The argument was used to justify far more than it should have.

The End of the Lobotomy Era

The procedure's decline came from two directions simultaneously. The first was the development of chlorpromazine (Thorazine) in 1952, the first effective antipsychotic medication. A drug that could control psychotic symptoms without brain damage immediately made the case for lobotomy much harder to sustain.

The second was accumulating evidence of harm. Studies that followed lobotomy patients long-term showed outcomes that Freeman's triumphalist accounts had obscured. The patients who seemed improved in short-term assessments were often simply quieter, more passive, less able to complain or resist. Long-term, many showed significant cognitive and personality deterioration.

Freeman performed his last lobotomy in 1967. The patient died of a brain hemorrhage. Freeman's hospital privileges were revoked. He died in 1972, reportedly still believing in the value of the procedure.

Moniz had a more dramatic end. In 1949, one of his former lobotomy patients shot him, leaving him partially paralyzed. He continued working and died in 1955. His Nobel Prize was never revoked.

The Lesson That Wasn't Fully Learned

Lobotomy is often presented as a dark chapter that medicine has cleanly moved past. The reality is more uncomfortable. The conditions that enabled it, overcrowded institutions, economic pressure to reduce patient numbers, willingness to accept superficial behavioral improvement as evidence of success, and insufficient long-term follow-up of invasive treatments, didn't disappear when the ice picks were put away.

The history of lobotomy is not primarily a story about one reckless doctor. It's a story about institutional failure, inadequate oversight, and the human capacity to mistake convenience for care. The patients who were destroyed by it deserve to be remembered as more than footnotes in medical history.
