Louis Pierre Vieillot (10 May 1748, Yvetot – 24 August 1830, Sotteville-lès-Rouen) was a French ornithologist.
Vieillot is the author of the first scientific descriptions and Linnaean names of a number of birds, including species he collected himself in the West Indies and North America and South American species discovered but not formally named by Félix de Azara and his translator Sonnini de Manoncourt. He was among the first ornithologists to study changes in plumage and one of the first to study live birds. At least 77 of the genera erected by Vieillot are still in use.
Vieillot was born in Yvetot. He represented his family's business interests in Saint-Domingue (Haiti) on Hispaniola, but fled to the United States during the Haitian rebellions that followed the French Revolution. On Buffon's advice, he collected material for the French: Histoire naturelle des oiseaux de l'Amérique Septentrionale, the first two volumes of which were published in France beginning in 1807.
Vieillot returned to France for the last time in 1798, where the position created for him at the Bulletin des Lois left him sufficient leisure to continue his natural history studies. Following the death of Jean Baptiste Audebert, Vieillot saw the two parts of the "Oiseaux dorés" through to completion in 1802; his own French: Histoire naturelle des plus beaux oiseaux chanteurs de la zone torride appeared in 1806.
Vieillot's French: Analyse d'une nouvelle Ornithologie Elémentaire (1816) set out a new system of ornithological classification, which he applied with slight modifications in his contributions to the French: Nouveau dictionnaire d'histoire naturelle (1816–1819). There was bitter rivalry between the leading ornithologists and the classification introduced by Vieillot was strongly criticized by Coenraad Temminck in a pamphlet published in 1817.[1] [2] In 1820, Vieillot undertook the continuation of the French: [[Tableau encyclopédique et méthodique]], commenced by Pierre Joseph Bonnaterre in 1790. He also published an French: Ornithologie française (1823–1830).
Towards the end of his life Vieillot became blind. He was granted a government pension in his final year but died in relative poverty.
Vieillot is now considered to be the authority for the scientific names of 88 genera and 402 species. Only Carl Linnaeus, Philip Sclater, and John Gould are considered to be the authority for more species. Viellot is commemorated in the scientific names of three birds: Lybius vieilloti (Vieillot's barbet), Coccyzus vieilloti (Puerto Rican lizard cuckoo) and Sphecotheres vieilloti (Australasian figbird).[3]
Some believe that Leach's Storm-petrel should be named Vieillot's Storm-petrel since he was the first to obtain a specimen of the species and to describe it. He did this in the New Dictionary of Natural History, published in 1817. He described the type location as the shores of Picardy, "se tient sur l"Ocean."
