Karol Olszewski

From Wikipedia, the free encyclopedia

Karol Stanisław Olszewski (b. January 29, 1846 in Broniszów - March 24, 1915 in Kraków) was a Polish chemist, mathematician and physicist.

In 1883 Olszewski, Zygmunt Wróblewski and Karol Sitarski were the first to liquefy oxygen, nitrogen and carbon dioxide from the atmosphere in a stable state (not, as had been the case up to then, in a dynamic state in the transitional form as vapour).

Olszewski studied at the Faculties of Mathematics and Physics, and of Chemistry and Biology at the Jagiellonian University. He carried out his first experiments using a personally improved compressor, condensing and compressing carbon anhydride (dioxide). He defended his doctoral dissertation at Heidelberg, after which he returned to his parent university, where he obtained the title of extraordinary professor.
