Louis Jean Pierre Vieillot
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. At least 26 of the genera erected by Vieillot are still in use. He was among the first ornithologists to study changes in plumage and one of the first to study  live birds. Biography. 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 "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 "Histoire naturelle des plus beaux oiseaux chanteurs de la zone torride" appeared in 1806. Vieillot's "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 "Nouveau Dictionnaire d'Histoire Naturelle" (1816–19). In 1820, Vieillot undertook the continuation of the "Tableau encyclopédique et méthodique", commenced by Pierre Joseph Bonnaterre in 1790. He also published an "Ornithologie française" (1823–30). Vieillot was granted a government pension in the final  year of his life, but died relatively unknown and in poverty. Vieillot is commemorated in the binomials of a number of birds, such as "Lybius vieilloti" (Vieillot's barbet) and "Saurothera vieilloti" (the Puerto Rican lizard-cuckoo). 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."
