Herbert George Wells trained as a biologist under Thomas Henry Huxley, then wrote novels describing atomic bombs and armored tanks decades before either existed; a physicist later said one of them planted the idea of a nuclear chain reaction in his head.

A boy in Bromley, Kent, broke his shin in 1874 and spent weeks in bed with nothing to do but read. That is a small, ordinary injury. It also produced, eventually, a body of fiction that predicted the atomic bomb, the tank, and a form of media panic that would not exist for another sixty years.

Herbert George Wells was born on September 21, 1866, the fourth child of a shopkeeper and former professional cricketer. Money was tight; his mother worked as a housekeeper at a country estate, and young Wells drifted through apprenticeships in drapery and pharmacy before a scholarship rescued him. At the Normal School of Science in South Kensington he studied biology under Thomas Henry Huxley, the anatomist known as "Darwin's Bulldog" for his public defense of evolution. Wells later called that year the most important of his life. It gave him a habit of thinking about species, extinction, and time scales that most novelists of his era never touched.

What made his early novels different?

By the mid-1890s Wells was turning that training into fiction nobody else was writing. The Time Machine (1895) sent its narrator hundreds of thousands of years forward to watch the sun cool and humanity split into two failing species. The Island of Doctor Moreau (1896) and The Invisible Man (1897) followed, each one using a scientific premise to ask what happens when power outruns conscience. None of it read like the adventure fiction of the day; it read like a biologist had gotten loose in a novel.

Then, in 1897, Pearson's Magazine in Britain and Cosmopolitan in the United States began serializing a new story: an invading Martian army lands in England and very nearly wins. The War of the Worlds appeared in hardcover the following year, and it did something Wells's earlier books hadn't: it set its catastrophe in real, named English towns, among people going about ordinary business, which is exactly what made it feel less like a fable and more like a warning.

Could fiction actually predict a weapon?

In 1903, Wells published a short story called "The Land Ironclads" in the Strand Magazine, describing hundred-foot armored vehicles that crossed trenches and broke infantry lines. Thirteen years later, at the Battle of Flers-Courcelette in 1916, the British army sent real tanks into combat for the first time. Winston Churchill, who chaired the wartime committee that developed them, is widely credited with having read Wells's story.

The more startling case came in 1914, with a novel called The World Set Free. Wells imagined a weapon he called an "atomic bomb," a device that released a continual, uncontrollable explosion of radioactive energy, used in a war he set decades into his own future. Nobody in 1914 knew how to split an atom, let alone weaponize it. Wells was guessing, and by his own account guessing loosely; the physics in the book is closer to poetry than to engineering.

Here is the part that is documented rather than merely plausible: the Hungarian physicist Leo Szilard read the novel and later wrote that it "made a very great impression on me." On September 12, 1933, Szilard was crossing Southampton Row in London, irritated by a newspaper account of a speech in which Ernest Rutherford dismissed the idea of harnessing atomic energy as "moonshine." Waiting at a traffic light, Szilard worked out the concept of a neutron-driven nuclear chain reaction, the mechanism that would eventually make a working bomb possible. He filed a patent on the idea the following year. Szilard did not claim the novel handed him the physics; he credited it with putting the idea of an atomic bomb in his head years before he had any means of building one, which is a narrower and more honest claim than it sometimes gets turned into.

The panic that made him famous to people who had never read him

Wells lived to see his fiction escape his control entirely. On October 30, 1938, Orson Welles and the Mercury Theatre on the Air adapted The War of the Worlds for CBS radio, staging it as a sequence of fake news bulletins interrupting a dance-music broadcast. Listeners who missed the opening disclaimer heard a Martian invasion of New Jersey reported as it happened. Newspapers the next morning ran stories of panicked callers and jammed switchboards; later research, including work by the historian W. Joseph Campbell, has argued the scale of that panic was considerably smaller and more localized than the legend suggests, inflated partly by newspapers eager to discredit a radio industry that was pulling their advertisers away. What is not disputed is that the broadcast made Wells's fifty-year-old plot recognizable to an American public that had mostly never opened the book, and it did so using exactly the mechanism, mass communication outrunning people's ability to verify it, that Wells had spent his career worrying about.

Wells kept writing for another two decades, publishing utopias and histories alongside more warnings, and drew four Nobel Prize nominations in literature without ever winning. In 1934, diabetic himself, he helped found what later became Diabetes UK. He died on August 13, 1946, a year after the weapon he had once merely imagined was used twice, in earnest, on two Japanese cities.

Why keep reading him now

Wells is easy to file as a curiosity, the man who guessed right a few times before better instruments existed. That undersells what he was actually doing, which was less prediction than pattern recognition: he watched what science was starting to make possible and asked, seriously, what a society untrained to handle it would do with it. The tools have changed since 1898. Machine learning systems and gene editors raise the same question Wells kept asking about his Martians and his atomic bombs, which is whether the people holding the new power have thought about it for longer than it takes to build it. That question has not aged out of relevance; if anything, each new technology puts it back in front of us.
