Claude Gay, often named Claudio Gay in Spanish texts, (March 18, 1800 – November 29, 1873), was a French botanist, naturalist and illustrator. This explorer carried out some of the first investigations about Chilean flora, fauna, geology and geography. The Cordillera Claudio Gay in the Atacama Region of Chile is named after him.
Research and travelsHe first went to Paris to study medicine, but he quickly abandoned this idea to become a researcher in natural history. In 1828, he went to Chile to teach physics and natural history at a college in Santiago. In 1829, he accepted a position as a researcher for the Chilean government to carry out a scientific survey of the country.
He returned to France in 1832, and gave his collections to the Muséum national d'histoire naturelle in Paris.
He returned to Chile in 1834 and explored the country again for four years. After having visited Peru in 1839, he lived in Santiago, where he wrote the multi-volume Historia fisica y politica de Chile. In 1841, Chile conferred the Chilean nationality to him, and his opus work was published by the Chilean government between 1844 and 1871.
Gay returned to France in 1843, and in May, 1856, he was elected a member of the French Academy of Sciences. He made a journey through Russia and Tartary from 1856-1858. At the end of 1858, he was sent by the French Academy of Sciences to study the mining system of the United States. He returned to France in 1860, and in 1863, he journeyed to Chile for the last time.
He is commemorated in the name of a number of plants and animals, including the flower Montiopsis gayana and the rufous-bellied seedsnipe Attagis gayi.
The journal of the Botanical Society of Chile, Gayana, is named in his honour and published by the Universidad de Concepción, Chile.
