This Swiss botanist (1806-1893), like Antoine-Laurent de Jussieu (see the posting of 8 August 2004 immediately below), was also the member of a family of distinguished French speaking botanists. Although born in Paris, he was Swiss and not French. At the International Botanical Congress of Paris in 1867 he drafted the Lois de la Nomenclature botanique which was adopted as the international rules of botanical nomenclature. This work stood without major revision until the "Rochester Code" of 1892, and still remains the basis of the current International Code of Botanical Nomenclature. A prolific author, he was Professor of natural history and Director of the botanic gardens at Geneva from 1835-1850.
