title: [Theophile-Jules Pelouze (1807-1867) was one of the French pharmacists who has the most contributed to the evolution of the organic chemisty in the first half of the 19th century].
abstract: Through some examples of his works, realized between 1833 and 1845 (studies on the tannin, the reaction of etherification, and on the nature of the chemical function of the glycerin), this article tries to bring to light his scientific approach. This one is not only based on the immediate analysis and the elementary analysis, but also on the study of characteristic chemical reactions, which are going to give him information onto the chemical nature and the constitution of the molecules which he studies. This approach will lead him finally to use these reactions not only in an analytical purpose but also in a purpose of synthesis.
