James Dewey Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped light the long fuse on a revolution in medicine, crimefighting, genealogy and ethics, has died, according to his former research lab. He was 97.<\/p>\n
The breakthrough \u2013 made when the brash, Chicago-born Watson was just 24 \u2013 turned him into a hallowed figure in the world of science for decades. But near the end of his life, he faced condemnation and professional censure for offensive remarks, including saying Black people were less intelligent than white people.<\/p>\n
Watson shared a 1962 Nobel prize with Francis Crick and Maurice Wilkins for discovering that deoxyribonucleic acid, or DNA, is a double helix, consisting of two strands that coil around each other to create what resembles a long, gently twisting ladder.<\/p>\n
That realization was a breakthrough. It instantly suggested how hereditary information is stored and how cells duplicate their DNA when they divide. The duplication begins with the two strands of DNA pulling apart like a zipper.<\/p>\n
Even among non-scientists, the double helix would become an instantly recognized symbol of science, showing up in such places as the work of Salvador Dal\u00ed and a British postage stamp.<\/p>\n
The discovery helped open the door to more recent developments such as tinkering with the genetic makeup of living things, treating disease by inserting genes into patients, identifying human remains and criminal suspects from DNA samples and tracing family trees. But it has also raised a host of ethical questions, such as whether the body\u2019s blueprint should be altered for cosmetic reasons or in a way that is transmitted to a person\u2019s offspring.<\/p>\n
\u201cFrancis Crick and I made the discovery of the century, that was pretty clear,\u201d Watson once said. He later wrote: \u201cThere was no way we could have foreseen the explosive impact of the double helix on science and society.\u201d<\/p>\n
Watson never made another lab finding that big. But in the decades that followed, he wrote influential textbooks and a best-selling memoir and helped guide the project to map the human genome. He picked out bright young scientists and helped them. And he used his prestige and contacts to influence science policy.<\/p>\n
Watson died in hospice care after a brief illness, his son said on Friday. His former research lab confirmed he had died a day earlier.<\/p>\n
\u201cHe never stopped fighting for people who were suffering from disease,\u201d Duncan Watson said of his father.<\/p>\n
Watson\u2019s initial motivation for supporting the gene project was personal: his son Rufus had been hospitalized with a possible diagnosis of schizophrenia, and Watson figured that knowing the complete makeup of DNA would be crucial for understanding that disease \u2013 maybe in time to help his son.<\/p>\n
He gained unwelcome attention in 2007, when the Sunday Times Magazine of London quoted him as saying he was \u201cinherently gloomy about the prospect of Africa\u201d because \u201call our social policies are based on the fact that their intelligence is the same as ours \u2013 where all the testing says not really\u201d. He said that while he hoped everyone was equal, \u201cpeople who have to deal with Black employees find this is not true\u201d.<\/p>\n
He apologized, but after an international furor he was suspended from his job as chancellor of the prestigious Cold Spring Harbor Laboratory in New York. He retired a week later. He had served in various leadership jobs there for nearly 40 years.<\/p>\n
In a television documentary that aired in early 2019, Watson was asked if his views had changed. \u201cNo, not at all,\u201d he said. In response, the Cold Spring Harbor lab revoked several honorary titles it had given Watson, saying his statements were \u201creprehensible\u201d and \u201cunsupported by science\u201d.<\/p>\n
He had shown \u201ca regrettable tendency toward inflammatory and offensive remarks, especially late in his career\u201d, Dr Francis Collins, director of the National Institutes of Health, said in 2019. \u201cHis outbursts, particularly when they reflected on race, were both profoundly misguided and deeply hurtful. I only wish that Jim\u2019s views on society and humanity could have matched his brilliant scientific insights.\u201d<\/p>\n
It was in the fall of 1951 that the tall, skinny Watson \u2013 already the holder of a PhD at 23 \u2013 arrived at Britain\u2019s Cambridge University, where he met Crick. As a Watson biographer later said: \u201cIt was intellectual love at first sight.\u201d<\/p>\n
Together they sought to tackle the structure of DNA, aided by X-ray research by colleague Rosalind Franklin and her graduate student Raymond Gosling. Watson was later criticized for a disparaging portrayal of Franklin in The Double Helix, and today she is considered a prominent example of a female scientist whose contributions were overlooked. She died in 1958.<\/p>\n
Watson and Crick built Tinker Toy-like models to work out the molecule\u2019s structure. One Saturday morning in 1953, after fiddling with bits of cardboard he had carefully cut to represent fragments of the DNA molecule, Watson suddenly realized how these pieces could form the \u201crungs\u201d of a double helix ladder.<\/p>\n
His first reaction: \u201cIt\u2019s so beautiful.\u201d<\/p>\n
Following the discovery, Watson spent two years at the California Institute of Technology, then joined the faculty at Harvard in 1955. Before leaving Harvard in 1976, he essentially created the university\u2019s program for molecular biology, Mark Ptashne, a scientist, recalled in a 1999 interview.<\/p>\n
Watson became director of the Cold Spring Harbor Laboratory in 1968, its president in 1994 and its chancellor 10 years later. He made the lab on Long Island an educational center for scientists and non-scientists, focused research on cancer, instilled a sense of excitement and raised huge amounts of money.<\/p>\n
Watson was born in Chicago on 6 April 1928, into \u201ca family that believed in books, birds and the Democratic party\u201d, as he put it. From his birdwatcher father he inherited an interest in ornithology and a distaste for explanations that didn\u2019t rely on reason or science.<\/p>\n
He got interested in genetics at the age of 17 when he read a book that said genes were the essence of life.<\/p>\n
At the time, it wasn\u2019t clear that genes were made of DNA, at least for any life form other than bacteria. But Watson went to Europe to study the biochemistry of nucleic acids like DNA. At a conference in Italy, Watson saw an X-ray image that indicated DNA could form crystals.<\/p>\n
\u201cSuddenly I was excited about chemistry,\u201d Watson wrote in The Double Helix. If genes could crystallize, \u201cthey must have a regular structure that could be solved in a straightforward fashion.<\/p>\n
\u201cA potential key to the secret of life was impossible to push out of my mind,\u201d he recalled.<\/p>\n
His 2007 remarks on race were not the first time Watson struck a nerve with his comments. In a speech in 2000, he suggested that sex drive is related to skin color. And earlier he told a newspaper that if a gene governing sexuality were found and could be detected in the womb, a woman who didn\u2019t want to have a gay child should be allowed to have an abortion.<\/p>\n
