Contemporary accounts give a vivid impression of Rosalie de Constant (1758-1834), the cousin of Benjamin Constant, the French novelist, politician and political philosopher. She was hunchbacked, but she played the mandolin and clavichord. She was short-sighted, and her attention to detail was expressed in an extensive set of paintings of Swiss plants.
She wrote sonnets, proverbs and an unfinished novel, but is most well known for her Herbier peint, a large work of 1245 plates, in which she painted illustrations of plants, wrote descriptions of their use, and classified them. Rosalie de Constant created this work between 1795 and 1832, and it was donated to the Musée cantonal in 1844, and is now held in the Musée botanique cantonal.
The University Library has two volumes of Rosalie’s letters, as well as a volume of her travel writing:
