Quantcast

de Candolle, Alphonse

Alphonse Louis Pierre Pyrame de Candolle (Paris October 28, 1806 – Geneva April 4, 1893) was a French-Swiss botanist, the son of the Swiss botanist A. P. de Candolle. Early in his studies he devoted himself to law. He gradually drifted to botany and finally succeeded to his father’s chair at the University of Geneva.

He published a number of botanical works, including continuations of the Prodromus in collaboration with his son,
Anne Casimir Pyrame de Candolle. He also is known for his creation of the first Code of Botanical Nomenclature, which was adopted by the International Botanical Congress in 1867 (known as the ICBN today). He was awarded the Linnean Medal of the Linnean Society of London in 1889.

Apart from botany, he is also known for a study of the religious affiliations of foreign members of the French and British Academies of Science during the Scientific Revolution that demonstrated that in both academies Protestants are more heavily represented than Catholics by comparison with catchment populations. This observation continues to be used as a demonstration that Protestants were more inclined to be scientifically active during the Scientific Revolution than Roman Catholics.
