DUTREUIL DE RHINS, Jules-Léon. Saint-Étienne ?.1.1846 — Tong-mbon-ndo near Sinang Fu 5.6.1894. French Marine Officer, Cartographer, Traveller and Explorer. Born in the Loire area, joined early the navy. In the 1870s captain. In 1876 he commanded the detachment of sixty men given to the king of Annam. DdR felt unhappy there and returned to France in 1877 continuing his career in navy as a cartographer. In 1882 in Egypt, in 1883 participated in the third Congo expedition of Brazza. Having been long time interested in Central Asia and carefully prepared for exploration there he was given in 1891 a grant of the Ministry of Education and of the A.I.B.L. for a journey to Lhasa and started immediately.
With his companion Fernand Grenard DdR travelled through Constantinople and Russia to Samarkand. In August-November 1891 they crossed the mountains (Altyn Tagh and Ustin Tagh) to Kashgar. Then through Takla Makan to Yarkand and Khotan, which was reached in July 1892. After three months’ stay they made an unsuccesful attempt to force their way into Tibet, returned in November and spent the winter in Khotan. With bought camels they decided to try a little used route through Tcherchen to the lake Tingri Nor. This route of 1000 km they travelled in September-December 1893 and reached a distance of 100/150 km from Lhasa. In the village of Nak Chou they were arrested by Tibetan cavalry, and after 50 days of unsuccesful negotiations decided to retreat in March 1894. Now they decided to circle Tibet from north and travelled 2000 km in three months. In the sources of Yangtse near Sinang Fu in the village Tong-mbon-ndo Tibetan villagers attacked the French travellers killing DdR and robbing and capturing Grenard, who was later sent home by Chinese officers.
DdR became originally interested in Tibet when he was preparing a map of Indochina and seeing the unknown north-western boundary. Ten years he planned his exploration. The expedition found, among other things, the famous Dutreuil de Rhins Manuscript of the Gandharī Dharmapada.
