Overview


Pharmacists isolated quinine from bark of the Cinchona Tree in back of their pharmacy.

Pierre-Joseph Pelletier (22 March 1788 – 19 July 1842) was a French chemist who did notable research on vegetable alkaloids, and was the co-discoverer of quinine and strychnine.  

Joseph Bienaimé Caventou (1795–1877) was a French chemist. He was a professor at the École de Pharmacie (School of Pharmacy) in Paris. He collaborated with Pierre-Joseph Pelletier in a Parisian laboratory located behind an apothecary. He was a pioneer in the use of mild solvents to isolate a number of active ingredients from plants, making a study of alkaloids from vegetables.
