An 18th-century Venetian scholar whose name became eternally attached to a deceptively simple differential equation that continues to puzzle and inspire mathematicians.
Jacopo Riccati (1676–1754) analyzed a single differential equation so deeply that his name became permanently attached to it. A gentleman scholar of the Italian Enlightenment, he pursued mathematics for pure intellectual delight, not a university post. Living in Venice and on his estate in Treviso, he corresponded with Leibniz and the Bernoulli family. His work featured elegant solutions to problems in calculus and differential equations, shared through letters rather than formal publications. He contributed to physics and hydraulics. The equation bearing his name was one he studied extensively, though he did not invent it. Special solutions found by contemporaries led to the term 'Riccati equation' entering mathematical lexicon. He was a capable amateur whose name, by academic fate, became standard vocabulary in advanced mathematics.

The world at every milestone
He declined several prestigious academic appointments, including offers from Peter the Great of Russia and the University of Bologna.
He was a trained lawyer and served as a magistrate in Venice, pursuing mathematics as a private study.
The Riccati equation is crucial in optimal control theory, used in modern engineering and economics.
His son, Vincenzo Riccati, was also a noted mathematician who continued his father's work.
“I study these equations for the pleasure of finding harmony in nature.”
