LIQUIFACTION OF OXYGEN
December 22, 1879 - Swiss, French
The liquefaction of oxygen was announced by Raoul Pierre Pictet (1846-1929), a Swiss chemist and physicist, by sending a telegram to the French Academy: Oxygen liquefied today under 320-atm and 140 degrees of cold by combined use of sulfurous and carbonic acid. French physicist Louis Cailletet made a similar announcement two days later. Pictet's early interest was in ice-making machines. Later, he studied extremely low temperatures and the liquefaction of gases. Both Pictet and Cailletet used both cooling and compression to liquefy oxygen but they achieved this using different techniques. Pictet's method had an advantage in that produced the liquid gas in greater quantity and was easier to apply to other gases.
