French botanist who, in 1850, experimented with sulfur as a remedy against powdery mildew, a fungus that had a serious negative impact on European grapes during the mid-19th century. The genus Duchartrea (family Gesneriaceae) was named in his honour. He is the binomial author of many species from the botanical family Aristolochiaceae.
In 1854 he was co-founder of the Société Botanique de France, an institution in which he served as president on several separate occasions. In 1861 he attained the chair of botany at the Sorbonne.
He died on 5 November 1894 in Meudon, aged 83.
