Raoul-Pierre Pictet (4 April 1846 – 27 July 1929) was aSwissphysicist. Pictet is co-credited with French scientistLouis-Paul Cailletet as the first to produce liquidoxygen in 1877.[1]
Pictet was born inGeneva. He served asprofessor in the university of that city. He devoted himself largely to problems involving the production of low temperatures and the liquefaction and solidification of gases.[2]
On December 22, 1877, theAcademy of Sciences inParis received a telegram from Pictet in Geneva reading as follows:Oxygen liquefied to-day under 320 atmospheres and 140 degrees of cold by combined use of sulfurous and carbonic acid. This announcement was almost simultaneous with that ofCailletet who had liquefied oxygen by a completely different process.[3]
Pictet died in Paris in 1929.[4]
