Person: Schauder, Juliusz Pawel

Julius Schauder was a Polish mathematician known for his work in functional analysis, partial differential equations and mathematical physics.

After the collapse of Austria, Schauder joined a new Polish army which was being organised in France.
He returned to Poland with this army in 1919, by this time the country of Poland had been reestablished and it was to a Polish Lwów that Schauder went.
Schauder had to teach in high school in order to supplement a meager income as lecturer ...
Schauder published fixed point theorems for Banach spaces in 1930.
While Schauder was in Paris he collaborated with J Leray and their joint work led to a paper Topologie et équations fonctionelles Ⓣ(Topology and functional equations) published in the Annales scientifiques de l'École Normale Supérieure.
By the time Schauder received this prize his final publication (1937) had appeared in print.
In particular, Schauder's formulation of a fixed point theorem originated a new, extremely fruitful method in the theory of differential equations, known as Schauder's method ...
The topological method developed in the 1934 Leray-Schauder paper ...
Schauder was treated well by the new Soviet administration.
Schauder sent pleas for help to Hopf and Heisenberg saying he had many important results but no paper to write them on.
We should comment on the picture of Schauder.
Schauder was there, as were Aleksandrov, Lefschetz, Borsuk, and some dozen other topologists.

Born 21 September 1899, Lemberg, Austrian Empire (now Lviv, Ukraine). Died September 1943, Lwow, Poland (now Ukraine).
