Patrick Cordier, born on December 29, 1946, in Besançon, and died on June 5, 1996, in Les Pennes-Mirabeau, was a French climber, mountaineer, and researcher. The son of teachers living in Paris, he discovered the mountains at a young age in Chamonix, where the family owned a chalet, and learned to climb on the crags of Fontainebleau and Saussois. A rock climber first and foremost, specializing in big walls and solo climbing, he became one of the best climbers of his generation within a few years. In 1967, he was the youngest member of the French team that established the direct route on Trollryggen, on the Trollveggen in Norway, a then legendary and feared face, which brought him international recognition in the mountaineering community. Between 1968 and 1970, he achieved several major first ascents on the limestone faces of southeastern France, notably the Duc wall in the Verdon Gorge with the route Les Enragés, as well as the Voûtes wall in the Dévoluy massif, establishing a committed style in which he deliberately limited the use of pitons. In the Mont Blanc massif, and more specifically in the Chamonix Aiguilles, Patrick Cordier opened or participated in the opening of routes that would become classics, such as the northwest pillar of the Grands Charmoz, later known as the Cordier Pillar. He played a key role in introducing "clean" climbing techniques to France, inspired by what he discovered in North America in the early 1970s. In 1972, during a trip to Alaska, Canada, and California, he made the third solo ascent of The Nose on El Capitan in Yosemite Valley, bringing back to Europe the systematic use of nuts and cams, which he then applied to the walls of Mont Blanc. A pioneer of this piton-free climbing in the Alps, he notably climbed the west pillar of Pointe Lépiney in 1975 and, most importantly, the south pillar of Aiguille de Roc, which would later bear his name and is considered the first major route opened in France using only nuts and cams. Simultaneously, he established an independent guiding company in Chamonix with Jean Afanassieff and the Bodin brothers, demonstrating his commitment to remaining free from traditional institutional constraints. A high-mountain guide and professor at the French National School of Skiing and Mountaineering (ENSA), he passed on his experience to a new generation of mountaineers. His activities expanded to include remote exploration: in 1975, he made the first ascent of Mount Ross in the Kerguelen Islands, the last unclimbed peak in French territory, roped up with Jean Afanassieff. He then participated in expeditions to the Karakoram, notably to K2, before achieving the first ascent of Bubuli-Mo-Tin and opening a new route on the second tower of Trango. Alongside his climbing career, Cordier conducted research in neuroscience. A figure both discreet and influential, often described as "outsider" and libertarian, Patrick Cordier profoundly marked the evolution of climbing through his pursuit of freedom, his ethic of calculated risk-taking, and his rejection of media hype. He died on June 5, 1996, at the age of 49, in a motorcycle accident on the highway between Aix and Marseille, leaving behind the image of a visionary mountaineer, whose routes still bear his name and his mark today.
