Charles Gaudichaud-Beaupré (September 4, 1789 – January 16, 1854) was a French botanist.
Gaudichaud was born in Angoulême, to J-J. Gaudichaud and Rose (Mallat) Gaudichaud. He studied pharmacology informally at Cognac and Angoulême, and then under Robiquet in Paris, where he acquired a knowledge of botany from Desfontaines and Louis Richard. In April 1810, he was appointed pharmacist in the military marine, and from July 1811 to the end of 1814, he served in Antwerp. He also studied chemistry and herbology.
His greatest claim to fame was serving as botanist on a circumglobal expedition from 1817 to 1820. He accompanied Freycinet, who made the expedition on the ships Uranie and Physicienne. The wreck of the Uranie in the Falkland Islands, at the close of 1819, deprived him of more than half the botanical collections he had made in various parts of the world. He is also known for his collections in Australia.
In 1831, Gaudichaud sailed on L'Herminie to South America, visiting Chile, Brazil and Peru. In 1836, he undertook a third voyage, circumnavigating the globe on La Bonite.
He died in Paris.
Gaudichaud is commemorated in the scientific names of two species of South American lizards, Ecpleopus gaudichaudii and Garthia gaudichaudii (the Chilean marked gecko),[1] and one species of Brazilian frog, Crossodactylus gaudichaudii.[2] Two Hawaiian species of flowering plants, in the genus Scaevola are named after him, Scaevola gaudichaudiana and Scaevola gaudichaudii.[3] [4] Also, a genus of South American plants in the family Malpighiaceae, Gaudichaudia, is named after Gaudichaud.[5]
He wrote various treatises, with memoirs on potato blight, the multiplication of bulbous plants, the increase in diameter of dicotyledonous plants, and other subjects.
