Stanisław Leśniewski and Kazimierz Ajdukiewicz were inspired by Husserl's formal analysis of language.

* Stanisław Leśniewski

Stanisław Leśniewski was perhaps the first to make widespread use of this distinction or fallacy, seeing it all around in analytic philosophy of the time, for example in Russell's Principia Mathematica ; at the logical level, a use – mention mistake occurs when two heterogeneous levels of meaning or context are confused inadvertently.

In this period Lukasiewicz and Stanisław Leśniewski founded the Lwów – Warsaw school of logic which was later made internationally famous by Alfred Tarski who had been Leśniewski's student.

* 1920 – 1939 professor at Warsaw University founds with Stanisław Leśniewski the Lwów – Warsaw school of logic ( see also Alfred Tarski, Stefan Banach, Hugo Steinhaus, Zygmunt Janiszewski, Stefan Mazurkiewicz )

* Stanisław Leśniewski

By early September he had gathered a group of mathematicians from Warsaw University and Lwów University ( most notably, founders of the Polish School of Mathematics — Stanisław Leśniewski, Stefan Mazurkiewicz and Wacław Sierpiński ), who were also able to break Russian ciphers.

Stanisław Leśniewski coined " mereology " in 1927, from the Greek word μέρος ( méros, " part "), to refer to a formal theory of part-whole he devised in a series of highly technical papers published between 1916 and 1931, and translated in Leśniewski ( 1992 ).

* Kazimierz Twardowski ( Vienna, 1885 – 1889 ), became father of the Lwów-Warsaw School of logic ( Jan Lukasiewicz, Stanisław Leśniewski, Tadeusz Kotarbiński, Kazimierz Ajdukiewicz and Alfred Tarski )

During the Polish – Soviet War ( 1919 – 1921 ), some one hundred Russian ciphers were broken by a sizable cadre of Polish cryptologists who included Army Lt. Jan Kowalewski and three world-famous professors of mathematics — Stefan Mazurkiewicz, Wacław Sierpiński and Stanisław Leśniewski.

Among his students were the logicians Stanisław Leśniewski, Jan Łukasiewicz and Tadeusz Czeżowski, the historian of philosophy Władysław Tatarkiewicz, the phenomenologist and aesthetician Roman Ingarden, as well as philosophers close to the Vienna Circle such as Tadeusz Kotarbiński and Kazimierz Ajdukiewicz.
