 After sociology had been readmitted to academic life in Poland in 1956, a group of sociologists at the universities of Warsaw and Łódź around Stanisław Ossowski set up a Sociological Section within the Polish Philosophical Association "(Polskie Towarzystwo Filozoficzne)", which became a member of the International Sociological Association (ISA) (of which Ossowski had already been a founding member in 1949).The following year, the section transformed into an independent body, adopting the traditional name "Polskie Towarzystwo Socjologiczne".Ossowski was elected its first president, other founding board members included Nina Assorodobraj, Józef Chałasiński, Antonina Kłoskowska, Jan Lutyński, Stefan Nowak, Zygmunt Pióro, Jan Strzelecki and Jan Szczepański.
