, and Lwów, where he finished school in 1920 and began studying mathematics at the Lwów Polytechnic University. He studied with Hugo Steinhaus, Antoni Łomnicki and Stanisław Ruziewicz, among others. As early as 1923 he took on small tasks at the Faculty of Mathematics. On August 1, 1925 he became a junior assistant at the Jan Kazimierz University in Lwów (now University of Lviv). He published his first scientific work in 1926 at the age of 23. In 1928 he completed his dissertation on the theory of orthogonal sequences. In 1929 he went to University of Göttingen on a scholarship and returned to Lemberg in 1930 as a senior assistant. In 1934 he presented his habilitation thesis The investigations of orthogonal systems. The following year he became an assistant professor at the Lwów Polytechnic University and received his teaching license at the University of Lwów.

In 1948 he was appointed full professor at the University of Poznań, where he remained until his retirement in 1970. He also worked at the State Institute of Mathematics, which was incorporated into the
