Jan Lukasiewicz 1878 – 1956

Jan Lukasiewicz (1878 – 1956) was a Polish philosopher of the Contemporary era, associated with Analytic Philosophy.

Jan Lukasiewicz was a Polish logician and philosopher and one of the founders of the Lwow-Warsaw school of analytic philosophy. After holding chairs at Lwow and Warsaw and serving briefly in independent Poland as minister of religious affairs and public education, he developed the first system of three-valued logic and a celebrated re-formalization of Aristotle's syllogistic. His Aristotle's Syllogistic from the Standpoint of Modern Formal Logic recovered the historical Aristotle for modern logic, while his polish notation removed the need for parentheses in formal expression. He spent his last years in exile at the Royal Irish Academy in Dublin.
