A French chemist noted for his work on catalysts used in organic chemical reactions. He worked on the industrial applications of hydrogenation and developed the use of nickel to facilitate the addition of hydrogen to carbon compounds. Working at the University of Toulouse, he rose to become dean of the faculty of science in 1905. He was awarded the Nobel Prize for Chemistry in 1912 together with French chemist François Auguste Victor Grignard (1871–1935). The Paul Sabatier University in Toulouse is named in his honour and the Sabatier process is named after him.
