Jean Baptiste Douville (1794–1837), French traveller, was born at Hambye, in the department of Manche. Having at an early age inherited a fortune, he decided to gratify his taste for foreign travel. According to his own profession he visited India, Kashmir, Khorasan, Persia, Asia Minor and many parts of Europe. In 1826 he went to South America, and in 1827 left Brazil for the Portuguese possessions on the West Coast of Africa, where his presence in March 1828 is proved by the mention made of him in letters of Castello Branco, the governor-general of Luanda.
In May 1831 he reappeared in France, claiming to have pushed his explorations into the very heart of central Africa. His story was readily accepted by the Société de Géographie of Paris, which hastened to recognize his services by assigning him the great gold medal, and appointing him their secretary for the year 1832. On the publication of his narrative, Voyage au Congo et dans l'interieur de l'Afrique Equinoxiale, which occupied three volumes and was accompanied by an elaborate atlas, public enthusiasm ran high.

Before the year 1832 was out, however, it was established that Douville's voyage was romance and not verity. He had probably been inspired by the appearance of René Caillié's account of his journey to Timbuktu, and wished to obtain a share of the fame attaching to African explorers. Douville tried vainly to establish the truth of his story in Ma Defense (1832), and Trente Mois de ma Vie, ou Quinze Mois avant et Quinze Mois aprés ma Voyage au Congo (1833).
