Edward Marczewski (1907–1976) – his family name was Szpilrajn, but he was forced to change it in 1940 to avoid persecutions. He was a student of the Warsaw School of Mathematics. His scientific interests focused around the set theory, topology, theory of real functions, analytical functions, theory of probability. Since 1945 he was Professor of the University of Wrocław; between 1953 and 1957 – he was the rector of the university, photo by Tadeusz Drankowski, Ossoliński National Institute.

Hugo Steinhaus (1887–1972) – one of the creators of the Lvov School of Mathematics, a professor of the Jan Kazimierz University of
Lvov, from 1945 a professor of the University of Wrocław. His scientific interests involved mathematical analysis, Fourier series, orthogonal expansions and linear operations, probability theory, as well as applications of mathematics in biology, medicine and technics. He was a wellknown popularizer of science and an aphorist, photo by Stanisław Kokurewicz, „Remembrance and Future” Center.

Bronisław Knaster (1893–1980) – he studied medicine in Paris and mathematics in Warsaw. He was a cofounder of the Warsaw
School of Mathematics, between 1939 and 1941 he was professor of Ivan Franko University in Lvov, and between 1945 and 1963 professor of the University of Wrocław. His scientific interests concerned topology, and especially the theory of continua. He was a co-organizer and employee of the PAN Mathematic Institute in Wrocław, photo by Tadeusz Drankowski, Ossoliński National Institute.

Władysław Ślebodziński (1884–1972) – he studied mathematics in Kraków and Göttingen. In 1921–1939 he was a lecturer in Poznań. During the war he was a teacher in secret teaching, he was arrested and sent to a concentration camp. From 1945 professor
