Gone Before 40: The Shortest Lives That Changed History

Galois at 20, Keats at 25, Schubert at 31: what the briefest careers in history managed to leave behind.

History's most haunting record book is the one measured in years withheld. The people below all died before forty — several before thirty — and yet each permanently altered their field. Their combined lifespans total less than four modern lifetimes; their combined legacy is beyond pricing.

The mathematicians

• Évariste Galois — 20. Killed in a Paris duel in 1832, leaving mathematics the theory of groups. His story appears among the great breakthroughs made before 26; no one else on that list had so little time.
• Niels Henrik Abel — 26. Died of tuberculosis in poverty, two days before a letter arrived with the Berlin professorship that would have saved him. The Abel Prize — mathematics' equivalent of a Nobel — now carries his name.
• Srinivasa Ramanujan — 32. The self-taught Madras clerk left notebooks whose formulas mathematicians are still proving and applying, a century on — including results now used in string theory and the study of black holes.

The musicians

• Franz Schubert — 31. Nearly 1,500 works, including 600 songs, a productivity record that stands among composers. His late masterpieces — the C major Quintet, the last three sonatas — were written in his final months, some unperformed for decades after.
• Wolfgang Amadeus Mozart — 35. The Requiem lay unfinished on his desk; the numbers of his impossible catalogue are told here.

The poets

• John Keats — 25. Tuberculosis took him in Rome in 1821, three years after the reviews that supposedly "killed" him. The odes he wrote in a single spring of 1819 are the core of English Romantic poetry. His gravestone reads, at his own bitter request: "Here lies one whose name was writ in water."
• Percy Bysshe Shelley — 29. Drowned sailing off the Italian coast in 1822, a month before his thirtieth birthday, with a book of Keats's poems in his pocket.

The painters

• Egon Schiele — 28. The Spanish flu of 1918 took him three days after his pregnant wife. In barely a decade he produced some three thousand works on paper.
• Amedeo Modigliani — 35. Died of tubercular meningitis in 1920; a century later his Nu couché sold for $170 million, one of the most expensive paintings ever.
• Jean-Michel Basquiat — 27. From subway graffiti to the summit of the art world in eight years; his skull painting Untitled sold in 2017 for $110.5 million, an American record at auction.

The scientist

• Henry Moseley — 27. His X-ray work gave the periodic table its true ordering principle, atomic number. Killed by a sniper at Gallipoli in 1915 — a loss so notorious that Britain thereafter kept its leading scientists from front-line service. Many historians assume the 1916 physics Nobel would have been his.

"I am certain of nothing but the holiness of the Heart's affections and the truth of Imagination."

— John Keats

The arithmetic of loss

Add the missing years — the four decades each of these minds was statistically owed — and you get several centuries of unwritten symphonies, unproved theorems and unpainted canvases. That is the true weight of this list: not what these short lives achieved, astonishing as it is, but the demonstrated rate at which they were achieving it when the clock stopped.

Frequently Asked Questions

Which great genius died youngest?

Évariste Galois, killed in a duel at 20, having already founded group theory — the youngest death among history's first-rank minds.

What did Ramanujan leave behind?

Notebooks containing thousands of results, some of which mathematicians are still proving and applying a century later, including in black-hole physics.

Why does tuberculosis appear so often on this list?

Before antibiotics it was the leading killer of young adults in Europe, claiming Keats, Abel, Chopin and many other artists and scientists in their prime.
