Jan Łukasiewicz (Polish: [ˈjan wukaˈɕɛvʲitʂ]; 21 December 1878 – 13 February 1956) was a Polish logician and philosopher born in Lwów, which, before the Polish partitions, was in Poland, Galicia, then Austria-Hungary. His work centred on analytical philosophy, mathematical logic, and history of logic. He thought innovatively about traditional propositional logic, the principle of non-contradiction and the law of excluded middle. Modern work on Aristotle's logic builds on the tradition started in 1951 with the establishment by Łukasiewicz of a revolutionary paradigm. The Łukasiewicz approach was reinvigorated in the early 1970s in a series of papers by John Corcoran and Timothy Smiley—which inform modern translations of Prior Analytics by Robin Smith in 1989 and Gisela Striker in 2009. Łukasiewicz is regarded as one of the most important historians of logic.
He grew up in Lwów and was the only child of Paweł Łukasiewicz, a captain in the Austrian army, and Leopoldina, née Holtzer, the daughter of a civil servant. His family was Roman Catholic.
He finished his gymnasium studies in philology and in 1897 went on to Lwów University (which, before the Polish partitions, had been in Poland), where he studied philosophy and mathematics. He was a pupil of philosopher Kazimierz Twardowski.
