Juliusz Paweł Schauder (21 September 1899 to October 1943) was a Polish mathematician known for his work in functional analysis, partial differential equations and mathematical physics. A representative of the Lwów School of Mathematics, he received his doctoral degree in 1923 from the Jan Kazimierz University in Lwów. In 1943, during World War II, he was murdered by Germans under unclear circumstances. Concepts in mathematical literature named after him include the Schauder basis, the Schauder fixed-point theorem, Schauder estimates, the Banach-Schauder theorem, the Leray-Schauder degree and the Faber-Schauder system.

Principal Result: Leray-Schauder Fixed-Point Theorem, Lead sentence of the article on the result
Schaefer's theorem is in fact a special case of the far reaching Leray-Schauder theorem which was proved earlier by Juliusz Schauder and Jean Leray.
Proofs Credited: Leray-Schauder Fixed-Point Theorem, Lead
The theorem was conjectured and proven for special cases, such as Banach spaces, by Juliusz Schauder in 1930.
