Mathematician:Stefan Banach

Polish mathematician who founded the modern field of functional analysis.

Most famous for his collaborative paper with Alfred Tarski in 1924, in which the Banach-Tarski Paradox was raised. This demonstrated that a contra-intuitive truth could be deduced from the ZFC axioms of set theory, specifically, by assuming the truth of the Axiom of Choice. Impassioned controversy rages to this day.
