Jan Łukasiewicz

Jan Łukasiewicz (1878–1956) was a Polish logician and philosopher. He produced pioneering works in mathematical logic, the history of logic, and the philosophy of logic. He was an innovative thinker who contributed to the understanding of traditional propositional logic, Aristotle’s syllogistic, and foundational principles of logic like the principle of non-contradiction and the law of the excluded third. Among his greatest achievements was the development of one of the first formalized systems of many-valued logic. As a historian of logic, Łukasiewicz approached the history of logic from the standpoint of modern formal logic. He is regarded as one of the most important historians of logic of the twentieth century.
