The Nobel laureate’s groundbreaking discovery revolutionized biology, but his legacy was marred by controversial remarks on genetics and race
James D. Watson, the American biologist who helped unravel the structure of DNA, launching the modern age of genetics and biotechnology, has died at 97. His death was confirmed by Cold Spring Harbor Laboratory, where he worked for decades.
Watson, who shared the 1962 Nobel Prize for describing DNA’s double helix, was arguably the most famous living biologist until repeated racist remarks turned him into a scientific outcast in his later years.
His journey—from prodigious young scientist to Nobel laureate to controversial figure—embodies both the boundless potential of scientific discovery and the profound ethical responsibilities that accompany it.
The Discovery That Changed Everything
In 1953, a mere 25 years old, Watson and British physicist Francis Crick deduced that DNA formed a double helix—a spiraling ladder with paired rungs. This “unzippable” structure immediately revealed how genetic information could be stored, copied, and passed between generations.
They described their finding in Nature with legendary understatement: “It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material”. What felt like “the discovery of the century” to Watson would eventually lead to genetic engineering, gene therapy, and DNA-based medicine.
The achievement earned Watson, Crick, and colleague Maurice Wilkins the 1962 Nobel Prize in Physiology or Medicine. Yet their success was shadowed by their use of X-ray crystallography data from Rosalind Franklin, who received insufficient acknowledgment for her foundational contributions.

Building a Scientific Empire
After his landmark discovery, Watson never matched that scientific high point, but he became a powerful force in shaping molecular biology. He joined Harvard University’s biology department in 1956, where he boldly championed molecular approaches over traditional biology.
In 1968, Watson began directing Cold Spring Harbor Laboratory (CSHL) on Long Island, transforming what was then a “mosquito-infested backwater” into a world-class research institution focused on cancer, neurobiology, and genetics.
“He had to figure out what to do with his life after achieving what he did at such a young age,” biologist Mark Ptashne noted. “He figured out how to do things that played to his strength”.
The Human Genome Project and Ethical Concerns
In 1990, Watson brought his prestige to the Human Genome Project, becoming its first director. He led the ambitious international effort to map all human DNA but resigned in 1992 on principle, opposing plans to patent gene sequences.
“He believed such information about nature should be generally available; otherwise, new research is jeopardized,” noted one biography. Watson also launched the Ethical, Legal, and Social Implications (ELSI) Research Program at the National Institutes of Health.
In 2007, he became only the second person to have his full genome sequenced, making it publicly available while excluding information about Alzheimer’s risk, a disease he feared.
A Controversial Legacy
Watson’s scientific reputation unraveled over repeated offensive comments:
- In 2007, he told The Times of London that he was “inherently gloomy about the prospect of Africa” because intelligence testing indicated Africans were “not really the same as ours”.
- The remarks, widely condemned as racist, led to his immediate suspension and forced retirement as CSHL chancellor.
- Although he apologized, Watson reiterated similar views in a 2019 PBS documentary, stating that differences in IQ testing between races were “genetic”.
- In response, CSHL stripped him of all honorary titles, severing their final ties and stating his views were “reprehensible” and “unsupported by science”.
These weren’t isolated incidents. Throughout his career, Watson made disparaging comments about women, boasted about chasing “popsies,” and made unsubstantiated claims about links between skin color and sex drive.
The Complex Man Behind the Science
James Dewey Watson was born in Chicago on April 6, 1928. A precocious student, he entered the University of Chicago at just 15. His early interest in birdwatching eventually evolved into a fascination with genetics, particularly after reading Erwin Schrödinger’s “What Is Life?”.
He earned his PhD from Indiana University in 1950, then conducted postdoctoral research in Europe before landing at Cambridge’s Cavendish Laboratory, where he met Crick.
Watson’s 1968 memoir, “The Double Helix,” offered a surprisingly candid—and controversial—glimpse into the competitive world of science. Francis Crick complained it “grossly invaded my privacy,” while others objected to its portrayal of scientists as ambitious schemers.
The book also drew criticism for its dismissive portrayal of Rosalind Franklin, referring to her as “Rosy” (a name she never used) and depicting her as difficult, while downplaying her critical scientific contributions.

Despite his public persona, Watson personally supported many female scientists. MIT biologist Nancy Hopkins stated, “I certainly couldn’t have had a career in science without his support. Jim was hugely supportive of me and other women”.
The Double Helix of Achievement and Controversy
Watson’s legacy represents a paradox—a scientist who helped unlock the secret of life while espousing views that threatened to diminish human dignity.
“Unlike most scientists, Watson’s legacy will always be colored by the 50 years of public commentary he also left behind in books, articles, interviews, and lectures,” said Georgia State University law professor Paul Lombardo, an expert on bioethics.
His death marks the passing of both a pioneering geneticist and a cautionary tale about how scientific brilliance doesn’t confer wisdom in all domains. As former NIH director Francis Collins noted, “I only wish that Jim’s views on society and humanity could have matched his brilliant scientific insights”.
Frequently Asked Questions
What exactly did James Watson discover?
Watson and Francis Crick discovered the double-helix structure of DNA in 1953—the twisted-ladder shape that allows genetic information to be stored and copied. This revelation earned them the Nobel Prize and founded modern molecular genetics.
Why was Watson controversial?
Watson made repeatedly controversial statements about race and intelligence, claiming Africans were less intelligent than other populations due to genetics. Most scientists reject these views as both racist and scientifically unfounded, noting that intelligence is influenced by numerous environmental factors.
What was Rosalind Franklin’s role in the DNA discovery?
Rosalind Franklin was an X-ray crystallographer whose data, particularly “Photograph 51,” provided critical evidence for the double helix structure. Watson and Crick accessed her research without her knowledge or proper attribution. Franklin died before the Nobel Prize was awarded, and many historians believe her contributions were insufficiently credited.
What was Watson’s role in the Human Genome Project?
Watson served as the first director of the Human Genome Project from 1988-1992. He resigned in protest over plans to patent human gene sequences, believing genetic information should remain in the public domain.
Where did Watson work throughout his career?
After his DNA discovery, Watson taught at Harvard University (1955-1976), then served as director, president, and chancellor of Cold Spring Harbor Laboratory from 1968 until his forced retirement in 2007.
