Charles Gaudichaud-Beaupré was a 19th-century French botanist and phycologist noted for botanical collections made during voyages of exploration and for taxonomic work on flowering plants and algae. He participated in circumnavigations and expeditions associated with European scientific institutions, produced descriptive floras and monographs, and influenced later naturalists and herbaria in Paris and beyond.
Born in Angoulême, Charente, Gaudichaud-Beaupré trained in the milieu of post-Revolutionary France during the Consulate and July Monarchy. He studied under professors associated with the Muséum national d'Histoire naturelle, interacted with contemporaries from the circles of Jean-Baptiste Lamarck, André Michaux, and botanists connected to the expeditions of Nicolas Baudin and Louis Duperrey. His early mentorship and links to botanical gardens in Bordeaux and the herbarium networks of Paris placed him in contact with collectors who had served on voyages with James Cook, Matthew Flinders, and explorers returning from New Holland and Van Diemen's Land.
Gaudichaud-Beaupré embarked on naval and scientific voyages that echoed the routes of Francis Garnier, Louis Isidore Duperrey, and earlier circumnavigators such as James Cook and William Bligh. He served as naturalist on the circumnavigation of the corvette La Physicienne under command linked to the French naval expeditions contemporary with Jacques Arago and collectors like Étienne Geoffroy Saint-Hilaire. His fieldwork included stops in regions associated with the exploration histories of Brazil, Chile, Peru, Tahiti, Hawaii (then the Sandwich Islands), Mauritius, Réunion, New South Wales, and the islands of the Pacific Ocean. During these voyages he exchanged specimens and correspondence with figures of the period such as Alexander von Humboldt, Aimé Bonpland, Charles Darwin, Joseph Dalton Hooker, and curators at the British Museum and Muséum national d'Histoire naturelle.
Gaudichaud-Beaupré published floristic accounts, monographs, and descriptive treatments reflecting taxonomic methods influenced by Carl Linnaeus and the botanical traditions of France and Britain. His works included systematic lists and botanical plates used by later taxonomists like Augustin Pyramus de Candolle, Alphonse Pyramus de Candolle, and John Stevens Henslow. He contributed to knowledge of Malpighiales, Fabaceae, Rutaceae, and algal groups studied by contemporaries such as William Henry Harvey and Jean Vincent Félix Lamouroux. His publications were cited by botanists compiling regional floras for South America, Oceania, Africa, and insular floras referenced in the bibliographies of George Bentham, Joseph Hooker, and editors at the Kew Gardens and the Herbarium of the Muséum national d'Histoire naturelle.
Gaudichaud-Beaupré described numerous plant taxa and his author abbreviation "Gaudich." is attached to species names in international botanical nomenclature overseen by bodies related to the International Code of Nomenclature for algae, fungi, and plants. Genera and species were dedicated to him by peers including Adrien-Henri de Jussieu, Erik Acharius-era lichenologists, and later commemorations by botanists connected with Kew and the Paris Herbarium. His specimens reside in major collections such as the Muséum national d'Histoire naturelle (Paris), the Royal Botanic Gardens, Kew, and herbaria that benefited from exchanges with curators like Pierre-Joseph Redouté-associated networks and collectors who worked with Joseph Banks and Robert Brown. Modern taxonomic revisions by researchers in systematic botany and phycology continue to reference his types and field notes preserved in archives alongside correspondence with figures such as Georges Cuvier, Isidore Geoffroy Saint-Hilaire, and Adrien de Jussieu.
Gaudichaud-Beaupré lived in the intellectual communities of Paris and maintained connections to scientific societies including the Académie des sciences and regional botanical societies analogous to those hosting presentations by Claude-Louis Berthollet and René Desfontaines. He died in Paris in 1854, leaving botanical collections, manuscripts, and a legacy reflected in plant epithets and citations in floras authored by Augustin Pyramus de Candolle, George Bentham, Alphonse de Candolle, and subsequent generations of naturalists who curated material at Herbarium collections in Europe and Australasia.
