Czesław Ryll-Nardzewski achieved his university entrance in the Vilnius, occupied by Germany, in secret school classes. After the war, he studied mathematics and physics at the Maria-Curie-Skłodowska University in Lublin, where he graduated in 1948. Subsequently, he moved to the University of Breslau, where he qualified as a professor in 1951 and was appointed an extraordinary professor in 1954 and then a full professor in 1964. From 1979 until his retirement in 1996, he taught at the Technical University of Breslau.
Ryll-Nardzewski has been a member of the Polish Academy of Sciences since 1967. He was editor of the journal Probability and Mathematical Statistics, co-editor of the Bulletin of the Polish Academy of Sciences, Colloquium Mathematicum, Fundamenta Mathematicae and Studia Mathematica.
In 1992, Ryll-Nardzewski was awarded the Stefan-Banach Medal.
Ryll-Nardzewski's areas of work were functional analysis, the fundamentals of mathematics, probability theory, and measure theory. A fundamental contribution to basic research is the theorem of Ryll-Nardzewski, according to which finite axiomatization of peano arithmetic is not possible. His theorem on characterization & # x03C9; {\displaystyle \omega } -categorical theories is also called the sentence of Ryll-Nardzewski. The fixed-point theorem of Ryll-Nardzewski from the Functionalanalysis carries his name.
