[Pierre-François Tingry (1743-1821), a Geneva pharmacist: his research in plant chemistry].

Tingry spent his entire professional and scientific career in Geneva, after completing his pharmacy studies in Paris. An important part of his writings, unpublished and conserved in Geneva, concerns plant chemistry. His work was principally devoted to the composition and varied parts of the flower Lilium album. Although he is classified as a minerologist and inorganic chemist, it is fitting to think of him also as a botanist and innovative talent in pharmacognosis.
