Descartes, Indre-et-Loire
commune in Indre-et-Loire, France
Descartes (French pronunciation: [dekaʁt] ) is a large village and commune in the Indre-et-Loire department in central France. It is approximately 29 kilometres east of Richelieu and about 48 kilometres east of Loudun, on the banks of the river Creuse, on the border with the Vienne department, which is also the regional border between Centre-Val de Loire and Nouvelle-Aquitaine.
It is famous as the birthplace of the French mathematician and philosopher who invented the Cartesian coordinate system, René Descartes.
History
Initially called La Haye-en-Touraine, the town was the birthplace of the philosopher René Descartes (1596–1650), who invented the Cartesian coordinate system, although his family home was in nearby Châtellerault. Descartes left La Haye in approximately 1606 to attend the College Henri IV at La Flèche. During World War II, the liberation of Descartes happened in 1944. The demarcation line was used as a border of Vichy France from 1940 to 1942. The town was renamed La Haye-Descartes in 1802 in his honour, and then renamed again Descartes in 1967.
In 1966, the commune of Balesmes was merged with the commune of Descartes, as the commune's population was increased to 4,627 in 1968, rather than its smaller population in 1962 (about 1,679 people).
Geography

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
