Career
Mazur made important contributions to geometrical methods in linear and nonlinear functional analysis and to the study of Banach algebras. He was also interested in summability theory, infinite games and computable functions. Mazur was a student of Stefan Banach at University of LwóWest
His doctorate, under Banach"s supervision, was awarded in 1935.
On 6 November 1936, he posed the "basis problem" of determining whether every Banach space has a Schauder basis, with Mazur promising a "live goose" as a reward: Thirty-seven years later, a live goose was awarded by Mazur to Per Enflo in a ceremony that was broadcast throughout Poland. From 1948 Mazur worked at the University of Warsaw.
