Adrien Dagory, born January 7, 1922 in Vanves (France) and died December 31, 2006 in Narbonne (France), was a French mountaineer, cameraman, and filmmaker. In 1952, he successfully climbed the west face of Les Drus, which many thought impossible with extensive use of aid climbing, with the Bleausards team of which he was a member: Guido Magnone, Lucien Bérardini, Adrien Dagory, and Marcel Lainé.

In 1954, he was part of a French expedition to the south face of Aconcagua, a 6,962-meter peak in Argentina. This expedition, led by René Ferlet, also included Lucien Bérardini, Guy Poulet, Robert Paragot, Pierre Lesueur, and Edmond Denis. There were no high-altitude Sherpas here, no one to share the hard work of the successive and grueling portages.
