Zygmunt Florenty Wróblewski (October 28, 1845 – April 16, 1888) was a Polish chemist and physicist. Wróblewski was born in Grodno (Russian Empire, now in Belarus). He studied at the Kiev University and after a six-year exile for participating in the January Uprising (1863), he studied in Berlin and Heidelberg. He defended his doctoral dissertation at the Munich University in 1876 and became an assistant professor of the Strassburg University. In 1880 he became member of the Polish Academy of Skills. He was introduced to the issue of gas condensation in Paris by professor Caillet at the École Normale Superieure. When he was offered the chair of the Faculty of Physics at the Jagiellonian University, he came to Kraków, where he began to study gases and soon began working with Karol Olszewski. While studying carbonic acid he discovered the CO2 hydrate. He reported this finding in 1882[1][2][3]. On 29 March 1883 they used a new method of condensing oxygen, and on 13 April of the same year - nitrogen. In 1888, while working on the physical properties of hydrogen, Wróblewski upset a kerosene lamp and was heavily burned, dying soon afterwards at a Kraków hospital. Karol Olszewski continued the experiments using an improved Picket cascade apparatus, and utilizing carbon dioxide, boiling ethylene in vacuum, as well as boiling nitrogen and boiling air as cooling agents.
