James Smithson
1765–1829 · 64 years Tier III
An illegitimate son of a duke who never saw America
He was born in secret, in Paris, sometime around 1765, and registered under a false name so the scandal would not follow his mother home. His father was Hugh Percy, later the first Duke of Northumberland; his mother, Elizabeth Macie, a widow with money of her own. English law made him nobody's heir. He was naturalized as James Louis Macie, took a degree at Pembroke College, Oxford, in 1786, and was elected to the Royal Society the next year at twenty-two, sponsored by Henry Cavendish. He spent the rest of his life moving through Europe's laboratories and salons, publishing on minerals and gases, never marrying, never settling, and never once crossing the Atlantic.
Smithson published around twenty-seven papers in his lifetime — on calamine, on tears, on snake venom, on the crystals that form in coffee cups — competent, minor work that a mineral, smithsonite, still commemorates. What made him matter was the will he wrote in London in 1826, leaving his fortune to a nephew, Henry James Hungerford, with a clause almost nobody expected to trigger: if the nephew died without children, the whole estate would go to the United States, a country Smithson had never visited, to found at Washington 'an Establishment for the increase and diffusion of knowledge among men.' He died in Genoa in 1829. The nephew died in 1835, unmarried and childless. In 1838 Richard Rush returned from London with eleven crates holding 104,960 gold sovereigns, and in 1846 Congress turned the money into the Smithsonian Institution.
Smithson's own words say what drove him better than any biographer could add: 'The best blood of England flows in my veins... but this avails me not. My name shall live in the memory of man when the titles of the Northumberlands and Percys are extinct and forgotten.' Illegitimacy had cost him the name Percy and any legal claim on his father's dukedom; the will was his answer to that erasure, aimed at a country that had nothing to do with the grievance. The irony he did not live to see: his own scientific legacy went up in flames. In 1865 a fire swept the half-finished Smithsonian Castle and destroyed his mineral collection, his papers, and his library, leaving almost nothing of the man's actual work inside the institution built to bear his name.
Smithson never set foot in the United States, alive or dead, until 1904. His grave in Genoa's Protestant cemetery sat undisturbed for seventy years, until a planned quarry threatened to destroy it; Alexander Graham Bell, then a Smithsonian regent, sailed to Italy in 1903, exhumed the remains, and delivered them to Washington under military escort. They were entombed in a crypt built into the Castle's north entrance in 1905, intended as temporary and never moved again. The institution his gold started has grown into a sprawling complex of museums, galleries, and research centers that carries his name into rooms he never imagined and would never see.
