Raoul Pictet
Raoul Pierre Pictet (born April 4, 1846 in Geneva , † July 27, 1929 in Paris ) was a Swiss physicist with a research focus in the field of low-temperature physics .
After studying in his hometown of Geneva and in Paris, Raoul Pictet took part in the opening of the Suez Canal in 1869 as secretary to the Swiss envoy and worked in Egypt from 1871 to 1874. When he returned to Geneva, he initially worked as a teacher, and from 1879 as a professor at the University of Geneva . There Pictet showed that hydrogen , nitrogen and oxygen using high pressure and low temperatures in the liquid aggregate state can be converted and even fixed can be. Louis Paul Cailletet in Paris achieved similar results around the same time with another technical application.
In 1881 Pictet described the principle of the glider for the first time in its patent specification “Innovations in Hulls” . In it he also indicated the important connection between overcoming the wave resistance.
Pictet lived in Berlin since 1886 , where he set up a laboratory for low-temperature physics and taught at Berlin University . He was also an entrepreneur, producing and selling refrigeration machines.
