## 1901 – Tarski – bio

Alfred Tarski was born in 1901 in Warsaw, Poland (then part of Russia) and was a mathematician and is considered to be one of the four greatest logicians of all time (along with Aristotle, Frege and Godel). In his first paper in 1921, he collaborated with Stephan Banach on the “Banach–Tarski paradox”, which describes a ball being broken into pieces and then re-assembled into two complete duplicates of the original.

Tarski’s papers include:

- 1935 – Geometry
- 1936 – Introduction to Logic and to the Methodology of Deductive Sciences
- 1948 – A decision method for elementary algebra and geometry
- 1949 – Cardinal Algebras
- 1953 – Undecidable theories
- 1956 – Logic, semantics, metamathematics
- 1956 – Ordinal algebras

His work ranged across the fields of pure logic, algebra, geometry, set theory, model theory, group theory, topology, relation algebra, and more.
