Z badań nad dziejami i spuścizną polskich filozofujących przyrodników w Kijowie w latach 1900–1919. Część 1: Czesław Białobrzeski / From the research on the history and legacy of Polish philosophical naturalists in Kiev in 1900–1919. Part 1: Czesław Białobrzeski

The aim of this paper is to present less known facts of Czesław Białobrzeski’s life from the period before he left Kiev in 1919 and his familiar works from that period. Particular emphasis is placed on biographical details, some aspects of the creation of his most famous work, and his popularization activities and philosophical interests, especially regarding science and the influence of French conventionalism. 

It turns out that in works such as “Reality in terms of natural science” or “The Principle of Relativity and some of its applications”, Białobrzeski appears to be a naturalist very well versed in philosophical topics related to sciences. The story behind Białobrzeski’s most famous work, “Sur l’équilibre thermodynamique d’une sphère gazeuse libre” which emerges from his correspondence with Władysław Natanson, is also interesting.
