He sheltered several people persecuted by the Terror, including Roland and Louis-Marie de La Révellière-Lépeaux. It was at this time he became tutor to Eudora Roland, Roland's daughter. La Réveliière-Lépeaux, having become a member of the Directoire, allowed Bosc to leave for the United States, first as vice-consul to Wilmington in 1797, then as consul to New York in 1798. Upon his return to France, he published Memoire sur quelques especes des champignons des parties meridionales de l'Amerique septentrionale (1811). This work was the first-ever systematic examination of the mushrooms of the southern United States, and established Bosc as the founder of mycology in that region. Bosc was brought back to France, where he served for a time as administrator of hospitals and prisons and obtained, in 1803, after a sojourn in Switzerland and Italy courtesy of Georges Cuvier, a position in the gardens and nurseries of Versailles. He gave his collections to his naturalist friends. Thus, Fabricius and Guillaume-Antoine Olivier received his insects; François Marie Daudin, his birds; Pierre André Latreille, his reptiles; and the comte de Lacépède, his fish. He was also the friend and protector of naturalists Jean-Baptiste Bory de Saint-Vincent and Jean-Marie Léon Dufour. In 1806, he was elected to membership in the Académie des sciences in the rural husbandry section. In 1825, he succeeded André Thouin to the chair of plant culture at the National Museum of Natural History in Paris. He died unexpectedly not many years later in Paris, in 1828. Legacy Bosc's legacy lies mainly in the fields of agronomy and natural history. He was the author of three volumes of Suites à Buffon, edited by René Richard Louis Castel: Histoire naturelle des Coquilles (Paris, 5 volumes, 1802); Histoire naturelle des Vers (Paris, 3 volumes, 1802); and Histoire naturelle des Crustacés (Paris, 2 volumes, 1802). Bosc participated in the editing of the Nouveau Dictionnaire d'histoire naturelle appliquée aux arts, principalement à l'agriculture, à l'économie rurale et domestique, under the direction of Jean-François-Pierre Deterville and Sonnini de Manoncourt (Paris, 24 volumes, 1803–1804, re-edited in 36 volumes, 1816–1819), and the Nouveau Cours complet d'agriculture théorique et pratique, also directed by Deterville (Paris, 13 volumes, 1809, re-edited in 16 volumes, 1821–1823). Bosc also supervised the editing and republication of the agricultural classic, Théâtre d'agriculture (1600) by Olivier de Serres, published by the Société centrale d'agriculture de Paris, whose Annales he also published.
