DUPEYTY-TRAHON, Jean-Ferdinand. Claire-Fontaine (Seine-et-Oise) 30.3.1794 — 1836. French Indologist. Son of an officer, who had served in India under Haidar ‘Ali, became interested in India through his father’s reminiscences. After studies of medicine in Paris became in 1813 the physician of the 150th regiment, but felt unhappy in the army and resigned after the defeat in 1814. Started now studies of everything somehow connected with India like Arabic, Persian, Sanskrit and Hindustani. Without visiting India he wrote a kind of encyclopedia, which was partly meant to serve as a travel guide. A great majority of the lemmata are in Urdu, in addition some Anglo-Indian and Sanskrit terms are included. This posthumous work was edited by Caüet.
