When World War II began, Banach was President of the Polish Mathematical Society and a full professor of University of Lwów . Being a corresponding member of Academy of Sciences of the Ukrainian SSR, and otherwise on good terms with Soviet mathematicians, he was allowed to keep his chair despite the Soviet occupation, from 1939, of LwówL'viv in Ukrainian; Lvov in Russian; in Polish; Leopolis in Latin; Lemberg in German—see also cities' alternative names) is a city in western Ukraine with 830,000 inhabitants (an additional 200,000 commute daily from suburbs).

Lwów was incorporated into the Soviet Union after the war, and Banach died there before he could be repatriated to Poland.
Théorie des opérations linéaires (Teoria operacji liniowych, 1932) is regarded as Banach's most influential work. He also initiated and edited the Studia Mathematica series.
Stanislaw Marcin Ulam, another mathematician of the Lwów School of Mathematics, in his autobiography, attributes this to Banach:Banach was the founder of functional analysis; he also made important contributions to the theory of vector spaces, measure theory, set theory and other branches of mathematics.
