Original preparation of quinine by Pelletier and Caveton, 1820
In 1820, Pierre Joseph Pelletier (1788-1842), a French chemist, and Joseph Caventou (1795-1877), a French pharmacist, isolated quinine and extracted it from cinchona bark. Cinchona had long been used to treat fevers, most notably malaria. Quinine is what makes the bark so effective as a treatment for the disease. This preparation was made by Pelletier and Caventou and was collected by Captain Peter Johnston-Saint, one of Henry Wellcome’s agents, in 1934. It is shown here with similar examples (A182555 and A182556).
