The Double Helix

9 min read

Harvard University Press refused to publish it. Francis Crick was furious. Maurice Wilkins protested. And Rosalind Franklin, the scientist whose work had been essential to the discovery being described, was already dead and unable to respond at all.

The book that caused all this controversy was The Double Helix, James Watson's 1968 memoir about discovering the structure of deoxyribonucleic acid, commonly known as DNA. It would go on to become one of the most celebrated science books of the twentieth century—and one of the most criticized.

A New Kind of Science Writing

Before Watson's book, scientific memoirs tended to be dignified affairs. They emphasized the careful accumulation of data, the measured progression of ideas, the collegial sharing of knowledge. They were, in other words, rather boring.

Watson threw all of that out.

His book read like a thriller. There were heroes and rivals. There was a race against time—specifically, a race against the brilliant American chemist Linus Pauling, who was also trying to crack the structure of DNA. There were moments of despair and flashes of insight. There was a pub in Cambridge called The Eagle where Watson and Crick announced to the lunchtime crowd that they had discovered the secret of life.

The intimate, first-person style was shocking for its time. Watson didn't present himself as a dispassionate seeker of truth. He admitted to ambition, competitiveness, even pettiness. He described scientific research as it actually felt from the inside: messy, political, and deeply personal.

This honesty won the book enormous praise. In 1998, the Modern Library ranked it seventh among the hundred best nonfiction books of the twentieth century. In 2012, the Library of Congress named it one of eighty-eight "Books That Shaped America." For many readers, it was the first glimpse behind the curtain of how major scientific discoveries actually happen.

The Discovery Itself

To understand the book's significance, you need to understand what Watson and Crick actually discovered, and why it mattered so much.

By the early 1950s, scientists knew that DNA was the molecule responsible for heredity—the substance that carries genetic information from parents to children. But nobody knew what it looked like or how it worked. Understanding its structure would be the key to understanding life itself at the molecular level.

The answer turned out to be the double helix: two spiral strands wound around each other like a twisted ladder. The rungs of the ladder are made of paired chemical bases, and the sequence of these bases encodes genetic information. When a cell divides, the two strands unzip, and each serves as a template for building a new partner strand. It was an elegant solution to the problem of how life copies itself.

Watson and Crick figured this out in 1953, working at the Cavendish Laboratory in Cambridge, England. Along with Maurice Wilkins, they received the Nobel Prize in Physiology or Medicine in 1962. Watson was just twenty-five years old when they made the discovery—young even by the standards of a field where major breakthroughs often come from people in their twenties and thirties.

The Rosalind Franklin Controversy

Here is where the story gets complicated, and where Watson's book has drawn its sharpest criticism.

Rosalind Franklin was a brilliant X-ray crystallographer working at King's College London. Her photographs of DNA fibers—particularly the famous "Photo 51"—provided crucial evidence for the helical structure. Without her data, Watson and Crick might never have solved the puzzle when they did.

But Franklin died of ovarian cancer in 1958, at the age of thirty-seven. She never received the Nobel Prize, which is not awarded posthumously. And she could not respond when Watson's book appeared a decade later.

Watson's portrayal of Franklin was devastating. He depicted her as difficult, dowdy, and obstructionist. He called her "Rosy"—a nickname she disliked and her friends never used. He described her as unable to interpret her own data, when in fact she was close to solving the structure herself.

The book also glossed over a crucial ethical question: how did Watson and Crick get access to Franklin's data in the first place? Maurice Wilkins showed them Photo 51 without Franklin's knowledge or permission. This was a significant breach of scientific ethics, though it was treated almost casually in Watson's account.

Anne Sayre, a friend of Franklin's, published a corrective biography in 1975 called Rosalind Franklin and DNA. Sayre argued that Watson's portrayal was not just unflattering but fundamentally inaccurate. She documented the sexism Franklin faced throughout her career, the difficult working conditions at King's College, and the enormous barriers women encountered in science during that era.

To his credit, Watson acknowledged some of this in the book's epilogue. He wrote that his initial impressions of Franklin, "both scientific and personal, were often wrong." He praised her "superb work" and noted the "enormous barriers she faced as a woman in the field of science." But for many readers, the damage was already done by the time they reached the epilogue. The vivid, unflattering portrait in the main text is what stuck.

Why Harvard Refused

The controversy began before the book was even published. Watson was a professor at Harvard, and Harvard University Press was the natural choice for publication. But when Crick and Wilkins learned what was in the manuscript, they objected strenuously.

Crick felt that Watson had violated the implicit confidentiality of their collaboration. Private conversations, personal quirks, and unflattering moments were being exposed to the world. Scientific colleagues would be reading about each other's weaknesses and rivalries. It felt like a betrayal.

Wilkins had his own concerns. His complicated relationship with Rosalind Franklin was being laid bare, and not in a way that showed him in the best light either.

Harvard bowed to the pressure and dropped the book. It was eventually published by Atheneum in the United States and Weidenfeld & Nicolson in Britain. The controversy, of course, only increased public interest. The book became a bestseller.

The Critical Editions

Over the years, scholars have produced several annotated editions that help readers understand the full context of Watson's memoir.

In 1980, the geneticist Gunther Stent edited a Norton Critical Edition that collected both positive and negative reviews from the book's initial publication. It included responses from major scientific figures like Peter Medawar and Jacob Bronowski, as well as letters from Crick, Wilkins, and Watson himself. The biochemist Erwin Chargaff, who had been dismissive of Watson and Crick's work, refused to allow his critical review to be reprinted—a small act of ongoing scholarly warfare.

In 2012, a new annotated and illustrated edition appeared, timed to coincide with the fiftieth anniversary of the Nobel Prize. This version, edited by Alex Gann and Jan Witkowski, included more than three hundred annotations, facsimile letters, and previously unpublished photographs. It even restored a chapter that had been dropped from the original edition, describing Watson's holiday in the Italian Alps in 1952.

The New York Times science writer Nicholas Wade, reviewing this edition, noted that "anyone seeking to understand modern biology and genomics could do much worse than start with the discovery of the structure of DNA, on which almost everything else is based." Whatever its flaws, Watson's book remains essential reading for understanding how molecular biology became the dominant paradigm of twentieth-century life science.

From Page to Screen

In 1987, the British Broadcasting Corporation adapted Watson's memoir into a television film called Life Story. In the United States, it was broadcast under the more dramatic title The Race for the Double Helix.

The film starred Jeff Goldblum as Watson—an interesting casting choice that captured something of Watson's gangly, enthusiastic energy. Tim Pigott-Smith played Francis Crick, and Juliet Stevenson portrayed Rosalind Franklin. The script was written by William Nicholson, who would later earn Academy Award nominations for Shadowlands and Gladiator.

The dramatization won the 1988 British Academy of Film and Television Arts Award for Best Single Drama. It gave viewers who hadn't read the book a vivid sense of the competition, the eureka moments, and the human cost of scientific ambition.

The Larger Questions

Reading The Double Helix today raises questions that go far beyond one discovery or one book.

How should credit be assigned in collaborative scientific work? Watson and Crick built on data gathered by Franklin and others. They benefited from conversations with colleagues, from access to unpublished results, from the entire ecosystem of postwar molecular biology. The Nobel Prize went to three men. Was that fair?

How honest should scientific memoirs be? Watson's candor was refreshing, but it also caused real harm to real people. Is it better to maintain professional discretion, or to tell the truth about how science actually works?

And what do we owe to the scientists who are overlooked, especially when that overlooking is systematic rather than accidental? Rosalind Franklin was not the only woman whose contributions were minimized or forgotten. Her story has become a symbol of a much larger pattern.

Watson, now in his nineties, remains a controversial figure. He has made remarks about race and intelligence that have been widely condemned as racist, leading to the revocation of honorary titles and his departure from Cold Spring Harbor Laboratory, the institution he led for decades. His legacy is complicated in ways that extend far beyond the pages of his most famous book.

Why It Still Matters

Despite all the controversy—or perhaps because of it—The Double Helix remains essential reading for anyone interested in how science works.

The discovery it describes transformed our understanding of life. The Human Genome Project, genetic engineering, CRISPR gene editing, mRNA vaccines—all of these developments trace back to the moment when Watson and Crick figured out that DNA was a double helix. Modern biology is unimaginable without that insight.

The book itself transformed science writing. After Watson, it became possible—even expected—for scientists to write about their work with personality and passion. The sterile objectivity of earlier scientific memoirs gave way to something more human and more readable.

And the controversies the book sparked have never been fully resolved. We are still arguing about scientific credit, about the treatment of women in research, about the ethics of competition and collaboration. These are not historical questions. They are live issues in every laboratory, every university, every funding agency in the world.

Watson wanted to tell the story of how he felt at the time, not how he felt in retrospect. That choice made his book vivid and immediate. It also made it partial and unfair. Perhaps that combination—the excitement and the injustice, the brilliance and the blindness—is the most honest portrait of scientific discovery we have.
