Daniel Carleton Gajdusek was one of the most celebrated — and later notorious — scientists of the twentieth century. He won a Nobel Prize for discovering how a fatal brain disease spread among a remote New Guinea population, then years later admitted to sexually abusing boys he had brought to live in his home under the guise of adoption. Both facts are part of the historical record, and neither cancels out the other.
Early Life and Education
Gajdusek was born on September 9, 1923, in Yonkers, New York, to Karol Gajdusek, a butcher of Slovak descent, and a mother whose parents were Hungarian immigrants. He showed an early aptitude for science, working as a teenager at the Boyce Thompson Laboratories near his hometown, where he did chemical research on herbicidal compounds.
He went on to earn a degree in biophysics from the University of Rochester, graduating summa cum laude in 1943, before completing his medical degree at Harvard Medical School in 1946. He later did postdoctoral work in physical chemistry at Caltech under Linus Pauling, and trained in pediatrics and infectious disease at Harvard.
The Discovery That Made Him Famous
In the 1950s, after military service and research postings in Iran, Afghanistan, and Turkey, Gajdusek was introduced to a mysterious illness devastating the Fore people of Papua New Guinea. Known locally as “kuru,” the disease caused tremors, loss of coordination, and eventually death, and it was killing a disproportionate number of women and children in the region.
Gajdusek moved into the region, learned the local language, and performed autopsies on kuru victims. He found their brains were riddled with sponge-like holes — a pattern never described before. Through years of painstaking work, he showed the disease could be transmitted to primates by injecting them with infected brain tissue, and eventually traced its spread to a Fore funerary practice of eating the bodies of deceased relatives.
The discovery was groundbreaking: kuru turned out to be one of the first known examples of a disease caused by what would later be understood as a prion, an infectious misfolded protein rather than a bacterium or virus. This same family of diseases includes Creutzfeldt-Jakob disease and, later, mad cow disease. For this work, Gajdusek shared the 1976 Nobel Prize in Physiology or Medicine with Baruch Blumberg.
He spent the following decades as chief of the Laboratory of Central Nervous System Studies at the National Institutes of Health, publishing widely across virology, pediatrics, genetics, and anthropology.
Bringing Children to the United States
Over the course of his career, Gajdusek brought more than 50 children — most of them boys from Papua New Guinea and Micronesia — to live with him in the United States, arranging for many to be legally adopted. He described this as an effort to give them opportunities and an education they would not otherwise have had, and several of the boys did go on to attend American schools and universities with his support.
This arrangement was, at the time, publicly framed as philanthropy. It later became central to the criminal case against him.
Conviction for Child Sexual Abuse
In 1996, Gajdusek was charged with child molestation after the diary of one of the young men he had brought to the U.S. surfaced, describing sexual abuse. In 1997, Gajdusek pleaded guilty to charges involving the sexual abuse of a teenage boy who had lived in his household. He served twelve months in a U.S. prison.
Following his release, he moved to Europe, living in a kind of self-imposed exile rather than returning to the United States, and continued some scientific work from abroad. According to biographical accounts, he did not deny what he had done during this period and expressed views defending sexual contact between adults and children, which drew condemnation even from people who continued to defend his scientific legacy. Some colleagues at the time argued for leniency on the basis of his contributions to medicine — a position that remains controversial and is widely criticized today as minimizing the harm to his victims.
What’s confirmed vs. unconfirmed: The criminal conviction, the guilty plea, and the prison sentence are all matters of public record, confirmed by multiple independent sources including contemporary court reporting and his own institutional biographies. The full scope of how many children were affected has never been comprehensively documented in public records, and any specific number beyond his own household should be treated as unconfirmed.
Death
Gajdusek died on December 12, 2008, in Tromsø, Norway, at the age of 85. He never returned to live in the United States after his release from prison.
Why He’s Still Discussed Today
Gajdusek’s case is frequently cited in discussions about how scientific institutions and peers responded to sexual abuse allegations against a prominent, celebrated figure — and how professional achievement was, for a period, used as a mitigating factor in the response to his crimes. His scientific work on kuru remains a legitimate and significant part of the history of medicine, particularly in the study of prion diseases. His criminal conduct is an equally documented and inseparable part of his biography.
There is no current news event driving a wave of search interest in Gajdusek as of today; interest in him tends to be steady, research- and history-driven traffic from people encountering his name through prion disease research, true-crime discussions of scientific misconduct, or general Nobel Prize history — not a breaking story.

Frequently Asked Questions
What was Carleton Gajdusek famous for?
He was famous for discovering that kuru, a fatal brain disease among the Fore people of Papua New Guinea, was transmissible — work that helped establish the existence of prion diseases and earned him the 1976 Nobel Prize in Physiology or Medicine.
Was Carleton Gajdusek convicted of a crime?
Yes. In 1997, he pleaded guilty to child molestation involving a teenage boy who had lived in his household, and he served twelve months in a U.S. federal prison.
Did Gajdusek adopt children?
Yes, he brought more than fifty children, primarily boys from Papua New Guinea and Micronesia, to the United States over his career, and arranged legal adoption for many of them.
Is Gajdusek still alive?
No. He died on December 12, 2008, in Tromsø, Norway, at age 85.
Did Gajdusek keep his Nobel Prize after his conviction?
Yes. The Nobel Prize is not revoked for later criminal conduct, and Gajdusek remained listed as a laureate for his 1976 award.
Why do people still search for information about Gajdusek?
Most current interest comes from people researching the history of prion disease science, kuru, or cases where a person’s professional prestige affected how their crimes were handled — not from any recent news event.
A note on sourcing: the facts above are drawn from Gajdusek’s Wikipedia entry, his NIH institutional biography, Encyclopaedia Britannica, and contemporaneous professional obituaries (Neurology Today, MedLink Neurology). Any claim about the total number of children affected, or about details of his personal statements while living abroad, beyond what these sources confirm, should be treated as not independently verified.
