The Double Helix: James Watson’s Frank Personal Account of the Race to Discover DNA’s Structure
The Double Helix (1968) is an autobiographical account of the discovery of the structure of DNA, told in the first person. It narrates the events that led to one of the greatest scientific breakthroughs of all time: understanding the three-dimensional structure of deoxyribonucleic acid, the molecule of heredity. By identifying the structure of DNA, the molecule of life, Francis Crick and James Watson revolutionised biochemistry and won the Nobel Prize.

A Race Against the Best
Watson was only in his mid-twenties at the time, a young scientist eager to make his mark. His honest account of the exciting race against other world-class researchers to solve one of science’s greatest mysteries offers a dazzlingly clear picture of a world of brilliant scientists with great gifts, very human ambitions and bitter rivalries.
With a humility not spoiled by false modesty, Watson describes his and Crick’s desperate efforts to beat Linus Pauling to the Holy Grail of the life sciences: the identification of life’s basic building block. Few scientists have ever been so candid in putting into words the flavour of their work.
Ethics and Everyday Science
The book captures a host of ethical, civic and moral questions that are part of a scientist’s daily life. Watson’s behaviour is not always admirable, and his portrait of colleagues has been criticised, but the situations he found himself in will surely inspire more than one reader to pursue an academic career.
Cambridge, 1951–1953
Watson arrived at the Cavendish Laboratory in Cambridge in 1951 and found in Francis Crick, an older physicist turned biologist, the perfect partner: both believed that the structure of DNA could be found by building models guided by the available evidence. Their rivals included Linus Pauling at Caltech, the greatest structural chemist of the day, who published a three-stranded model that turned out to be wrong, and the team at King’s College London, Maurice Wilkins and Rosalind Franklin, who were producing the best X-ray images of DNA.
Rosalind Franklin
The book’s most controversial pages concern Franklin. Watson describes "Rosy" in condescending terms, and he recounts how Wilkins showed him one of her X-ray photographs, now known as Photo 51, without her knowledge; it gave him crucial evidence of a helix. Franklin died of cancer in 1958, aged thirty-seven, and the Nobel Prize of 1962 went to Watson, Crick and Wilkins. Watson’s epilogue acknowledges her achievement and his early misjudgement, but later writers, beginning with Anne Sayre’s biography of her in 1975, have restored her central role.
A Book Its Subjects Disliked
The manuscript was so frank that both Crick and Wilkins objected to it, and Harvard University Press, which had planned to publish it, withdrew. It appeared instead with a commercial publisher in 1968, with a foreword by Sir Lawrence Bragg, the director of the Cavendish. Its gossipy, personal tone, so unlike the usual image of science, is precisely what made it a bestseller and a model for later scientific memoirs.
Watson’s Later Years
Watson went on to a long career at Harvard and at Cold Spring Harbor Laboratory and was the first head of the Human Genome Project. His reputation was badly damaged late in life by public remarks about race, for which the laboratory stripped him of his honorary titles. He died in November 2025, aged ninety-seven.
Who Is It For?
The Double Helix is a classic of twentieth-century literature. You do not need to be well versed in biochemistry or molecular biology to understand the science. Compared with other famous popular-science books it is one of the most readable, with numerous illustrations. It is highly recommended for the general reader: a historical document of great value, told with the pace of a novel.
