Augustin Pyrame De Candolle
Candolle, Augustin Pyrame De
Born Feb. 4, 1778, in Geneva; died there Sept. 9, 1841. Swiss botanist. Student of G. Cuvier and J. Lamarck.
Candolle was coauthor of the completely revised third edition of Flora of France (1803-15). He was a professor at the universities of Paris (from 1802), Montpellier (from 1808), and Geneva (from 1816). In Geneva he founded the Botanical Gardens and the De Candolle Herbarium. He developed one of the first natural systems for the classification of plants and began publishing a compendium of all known varieties of angiosperms: Introduction to the Natural System of the Plant Kingdom (vols. 1-7, 1824-39; completed by his son Alphonse de Candolle). Candolle founded comparative plant morphology and introduced the concept of the plan of symmetry. He distinguished the similarity of organs according to their functions (analogy) and according to their structural pattern (homology) and extended the principle of correlation to plants.
