Karol Olszewski

Karol Stanistaw Olszewski

Karol Stanistaw Olszewski (1846-1915)

Chemist, physicist and expert of low temperatures; the first scholar who liquefied nitrogen and oxygen; he also discovered a method of hydrogen liquefaction and constructed machinery for that purpose, which enabled him to reach the then-lowest world temperature, -225 C.

Karol is an alumni of Jagiellonian University, as is Nicolaus Copernicus and Pope John Paul II.

The Copernicus Monument stands outside the Neoclassical Collegium Phisicum at Ul.Golebra. On its facade is a plaque commemorating the first liquefaction of oxygen, hydrogen, and nitrogen by Karol Olszewski and Walery Wroblewski in 1882:

The Collegium Maius has a room dedicated to Karol Olszewski (photography not allowed).

In addition, his painting hangs within the museum's main hall:

Karol Olszewski

and a street in Krakow was named after him:

Karol Olszewski

Karol Olszewski was my great grandfather's uncle. My father changed the spelling from Olszewski to Olshefski when he was in his 20's to avoid the constant mispronunciations. I visited Poland in September 2007.

Karol was born in Broniszow near Tarnow on Jan 29, 1846. In 1886, he entered the University of Krakow, as an assistant to the chemistry professor Czyrnianski. He succeeded in liquefying and solidifying carbon dioxide. He went to Heidelberg in 1872 where he studied uder Bunsen, Kirchoff and Blum. He received his degree "Insigni Cum Laude ". He returned to Krakow and met with Wroblewski, a newly appointed professor in physics. Karol's redesign of existing equipment allowed them to liquefy oxygen. April 9, 1883 a report was sent to the Academy of Science in Paris and is recognized as the date of the liquefaction of oxygen. Shortly after, the headstrong scientists parted company. Karol died on March 24th, 1915 in Krakow, Poland (at the time of his death, the city was part of the Austrian-Hungrian Empire, named "Krakau").
