Alfred Tarski
Alfred Tarski (/ˈtɑːrski/; Polish: [ˈtarskʲi]; born Alfred Teitelbaum; January 14, 1901 – October 26, 1983) was a Polish-American logician and mathematician. A prolific author best known for his work on model theory, metamathematics, and algebraic logic, he also contributed to abstract algebra, topology, geometry, measure theory, mathematical logic, set theory, type theory, and analytic philosophy.
Educated in Poland at the University of Warsaw, and a member of the Lwów–Warsaw school of logic and the Warsaw school of mathematics, in 1939 he immigrated to the United States, where in 1945 he became a naturalized citizen. Tarski taught and carried out research in mathematics at the University of California, Berkeley, from 1942 until his death in 1983.
His biographers Anita Burdman Feferman and Solomon Feferman state that, "Along with his contemporary, Kurt Gödel, he changed the face of logic in the twentieth century, especially through his work on the concept of truth and the theory of models."
Alfred Tarski was born Alfred Teitelbaum (Polish spelling: "Tajtelbaum") to Polish-Jewish parents in comfortable circumstances. He first showed mathematical ability in secondary school, at Warsaw's Szkoła Mazowiecka. Nevertheless in 1918 he entered the University of Warsaw intending to study biology.
After Poland regained independence in 1918, Warsaw University came under the leadership of Jan Łukasiewicz, Stanisław Leśniewski, and Wacław Sierpiński and quickly became a world-leading research institution in logic, foundational mathematics, and the philosophy of mathematics. Leśniewski recognized Tarski's potential as a mathematician and encouraged him to abandon biology.
Tarski attended courses taught by Łukasiewicz, Sierpiński, Stefan Mazurkiewicz, and Tadeusz Kotarbiński and in 1924 became the only person ever to complete a doctorate under Leśniewski's supervision. His thesis, O wyrazie pierwotnym logistyki (On the Primitive Term of Logistic), was published in 1923.
Tarski and Leśniewski soon grew cool to each other, mainly due to Leśniewski's growing anti-semitism. In later life, however, Tarski expressed the warmest praise (which was reciprocated) for Kotarbiński.
In 1923 Alfred Teitelbaum and his brother Wacław changed their surname to "Tarski". The brothers also converted to Roman Catholicism, Poland's dominant religion: Alfred, even though he was an avowed atheist.
