Jean Henri Jaume Saint-Hilaire (October 29, 1772 – 1845) was a French naturalist and artist, born in Grasse, France.
Born as Jaume, he added Saint-Hilaire later. Some biographers indicate that this addition was to distinguish himself from a family member, Henri-Honore Jaume, a Jacobin who had been involved in the Reign of Terror, during the French Revolution. He served in the French Army during the , before returning to civilian life in 1800. He then returned to Paris and resumed his studies, especially natural history. He wrote a guide to the new Muséum National d'Histoire Naturelle, and learned floral painting from Gérard van Spaendonck (1746-1822).
In 1805 he wrote his first important publication: Exposition des familles naturelles et de la germination des plantes, contentant la description de 2 337 genres et d'environ 4 000 espèces, 112 planches dont les figures ont ete dessinées par l'auteur [An exposition about natural families and the germination of plants, containing the description of 2,337 genera and about 4,000 species, 112 plates whose figures were drawn by the author]. In it, he popularized the classification of Antoine-Laurent de Jussieu (1748-1836). During 1808-1809 and 1819âÂÂ1822, Jaume published ten volumes about French plants: Plantes de la France décrites et peintes dâÂÂaprès nature [French plants described and painted from nature], grouping together one thousand engravings that he had made himself.
Jaume was quite interested in forests, and became a member of ' in 1831. He also became interested in the culture of Wrightia tinctoria, a member of the plant family Apocynaceae used for its dyeing qualities.
