The Lobotomy: How a Nobel Prize-Winning Procedure Became Medical Disgrace

A Nobel Prize Was Awarded in 1949 for a Procedure That Damaged Tens of Thousands of Patients

António Egas Moniz, a Portuguese neurologist, received the 1949 Nobel Prize in Physiology or Medicine for his development of the prefrontal leucotomy — a procedure that severed connections between the frontal lobes and the rest of the brain as a treatment for severe psychiatric illness. Moniz had performed his first leucotomy in 1935. By the time he received the Nobel, tens of thousands of lobotomies had been performed worldwide, and the procedure's devastating effects on personality, cognition, and human functioning were already well documented in the medical literature.

The story of the lobotomy is not simply a story of medical error or ignorance. It is a story of how psychiatric desperation, institutional convenience, ambitious operators, inadequate follow-up, and the absence of controlled clinical trials combined to make a harmful procedure celebrated as a triumph before its damage could be systematically measured. The Nobel Prize for lobotomy remains the most controversial award in the prize's history, and repeated petitions to the Nobel Committee to posthumously revoke it have been declined on the grounds that the prize cannot be returned.

The Psychiatric Context: Why Anyone Tried This

To understand why lobotomy was embraced, one must understand the condition of psychiatry in the 1930s. State psychiatric hospitals in the United States and Europe were chronically overcrowded, understaffed, and had essentially no effective treatments for the most severe conditions: schizophrenia, severe depression, obsessive-compulsive disorder, and manic episodes. Patients were institutionalized for decades. Available treatments were limited to hydrotherapy (prolonged baths), restraints, barbiturate sedation, and, from the early 1930s, insulin coma therapy (deliberately inducing hypoglycemic coma) and Metrazol convulsive therapy (chemically inducing seizures) — all dangerous and of limited efficacy.

The overworked psychiatrists who ran these institutions were desperate for anything that might allow patients to be discharged, or at least managed without physical restraint. A surgical intervention that reduced agitation and made patients more docile — even at the cost of cognitive function and emotional depth — was evaluated by many administrators primarily in terms of its institutional management benefits, not its effect on the patient's inner life.

Moniz to Freeman: From Europe to American Mass Production

Egas Moniz began his procedure in 1935, drilling holes in the skull and injecting pure alcohol to destroy frontal lobe tissue. He later refined the technique to use a leucotome — a wire loop that could be rotated to cut a core of tissue. His published results claimed improvement in a majority of patients, though his follow-up methodology was inadequate by any modern standard. The Nobel Committee's decision in 1949 was based substantially on these papers.

American neurologist Walter Freeman and neurosurgeon James Watts saw Moniz's reports and began their own series of operations in 1936. Freeman became the procedure's most prolific and enthusiastic American promoter. He performed or supervised more than 3,000 lobotomies in his career. His signature innovation was the "transorbital lobotomy," developed in 1945: using a modified ice pick (or a purpose-made instrument called an orbitoclast) inserted through the thin bone of the upper eye socket, Freeman could reach the frontal lobes without drilling the skull. The procedure took about 10 minutes, could be performed under electroconvulsive shock rather than general anesthesia, and did not require a neurosurgeon.

Rosemary Kennedy and the Cost of Secrecy

Among the most discussed individual cases of lobotomy is Rosemary Kennedy, the third child of Joseph P. Kennedy Sr. and Rose Kennedy, and sister of President John F. Kennedy. In November 1941, Joseph Kennedy authorized a lobotomy for 23-year-old Rosemary, who had intellectual disabilities (likely from oxygen deprivation at birth) and was experiencing mood swings and behavioral difficulties that embarrassed the family's political ambitions and social standing.

The outcome was catastrophic. The procedure, performed by Freeman and Watts while Rosemary remained conscious, left her permanently incapacitated: she lost the ability to speak coherently, lost control of her left side, and required institutional care for the rest of her life. She lived until 2005, spending 64 years at Saint Coletta's School in Wisconsin. The family kept her existence secret for over 20 years; she was absent from all public Kennedy family events until 1962, when Eunice Kennedy Shriver's founding of the Special Olympics (partly inspired by Rosemary's condition) brought intellectual disability into public conversation.

The Scientific Critique Grows and Chlorpromazine Arrives

By the late 1940s, serious critical literature was accumulating. Nolan Lewis and other American psychiatrists published studies showing that lobotomized patients who appeared "improved" had in fact been reduced to a child-like dependency with blunted emotions, impaired judgment, and incontinence — outcomes the procedure's proponents counted as success because they were no longer disruptive. The mortality rate from the procedure was approximately 3–4% from direct surgical complications, with higher rates in some series.

The lobotomy's decline accelerated sharply after 1954 with the introduction of chlorpromazine (Thorazine), the first effective antipsychotic medication. A drug that could reduce the hallucinations and agitation of schizophrenia without brain damage was instantly preferable to surgery. The Joint Commission on Mental Illness and Health's 1961 report endorsed outpatient treatment and the deinstitutionalization movement further reduced the institutional pressures that had driven lobotomy's adoption.

• Approximately 40,000–50,000 lobotomies were performed in the United States between 1936 and the mid-1950s
• An estimated 100,000 were performed worldwide, with the UK performing about 17,000 and Scandinavia and other European countries performing additional thousands
• The Soviet Union banned lobotomy in 1950 as "contrary to the principles of humanity" and inconsistent with Communist ideology's materialist view of consciousness
• The last known lobotomy performed in the United States by Walter Freeman resulted in the death of Helen Mortensen in 1967; the hospital revoked his surgical privileges

The Nobel Prize That Cannot Be Revoked

The Nobel Committee has received multiple petitions to revoke Moniz's prize, the most notable organized by survivors and disability rights advocates. The Committee has consistently declined, citing its policy that Nobel Prizes are never revoked regardless of subsequent developments. The Committee's position acknowledges that Moniz's work reflected contemporary evidence standards but notes that the prize was awarded "for the discovery of the therapeutic value of leucotomy in certain psychoses" — language that critics argue reflects the same inadequate evidence base that allowed the procedure to spread unchallenged for two decades.
