context_page_description: Gaston Gradis was a French businessman and explorer. He came from a wealthy family of Bordeaux shipowners. After serving as an artillery captain in World War I, he became the head of various transport and trading businesses. He is known for having undertaken the first crossing of the Sahara by automobile in 1924.
context_section_description: Gradis directed the first expedition to cross the Sahara from north to south by car. For this purpose, on 23 May 1923 he founded the Compagnie générale transsaharienne (CGT). The retired General Jean Baptiste Eugène Estienne, who had designed and built tanks during the war, was made president of the company. The purpose of the company was to "study, establish and exploit land and air communications between the various territories of the African continent, particularly between Algeria and Niger." An exploratory mission was sent under Georges Estienne, son of General Estienne, with his brother René and lieutenant Hubel, accompanied by four legionnaires and four Citroën mechanics. The mission left Adrar on 17 November 1923, reached Tessalit on 30 November, and returned to Adrar on 13 December, having mapped a shorter route than those known before, over excellent terrain.
  Gaston Gradis headed a second exploratory expedition that left Colomb-Béchar at midnight on 25 January 1924 with three large six-wheel Renault cars with double tires. Gradis was accompanied by the Estienne brothers, M. Schwob, an engineer from Renault, and three mechanics. A rival Citroën expedition had left a day before, and the press made great play of the competition, which Gradis thought obscured the important goal of establishing a trans-Saharan route. After reaching Adrar the expedition left for the south in two vehicles, following the tracks of the November reconnaissance expedition, which were still visible. The six-wheel cars proved faster than the Citroën caterpillars. This expedition reached Gao, on the Niger River, and returned to Béchar on 1 March 1924. Gradis was optimistic about the potential for aerial travel along this route.
  The second Gradis expedition left Colomb-Béchar on 15 November 1924 in three six-wheel Renaults. Gradis was accompanied by the journalist Henri de Kérillis, and Marshal Louis Franchet d'Espèrey was accompanied by commandant Ihler. The Estienne brothers again joined the expedition. The other members were three Renault mechanics and three legionnaires. The expedition reached Savé in Dahomey on 3 December 1924 after a journey of 3,600 kilometres (2,200 mi). The expedition leaders took the train south, and reached Porto-Novo on the Atlantic on 14 December 1924. They then returned to Europe by boat, while the Estienne brothers raced back from Savé to Colomb Bechar in six days, setting a new record for long-distance speed in Africa.
