DUVEYRIER, HENRI (1840-1892), French explorer of the Sahara, was born in Paris on the 28th of February 1840. His youth was spent partly in London, where he met Heinrich Barth, then preparing the narrative of his travels in the western Sudan. At the age of nineteen Duveyrier, who had already learnt Arabic, began a journey in the northern parts of the Sahara which lasted nearly three years. On returning to France he received, in 1863, the gold medal of the Paris Geographical Society, and in 1864 published Exploration du Sahara: les Touareg du nord. In the war of 1870 he was taken prisoner by the Germans. Subsequently he made several other journeys in the Sahara, adding considerably to the knowledge of the regions immediately south of the Atlas, from the eastern confines of Morocco to Tunisia. He also examined the Algerian and Tunisian shats and explored the interior of western Tripoli. Duveyrier devoted special attention to the customs and speech of the Tuareg, with whom he lived for months at a time, and to the organization of the Senussi. In 1881 he published La Tunisie, and in 1884 La Confrérie musselmane de Sidi Mohammed Ben Alî-Es-Senôusi et son domaine géographique. He died at Sevres on the 25th of April 1892.
