He was born Raymond Jules Eugene Lambert in Geneva, where he made his home for his entire life. Lambert was member to a group of elite Genevois climbers. With this group, Lambert tested his skills against French, German and Italian rivals to become the first ascenders of the hardest new climbs in the Mont Blanc Range. Second ascents of the Croz Spur on the Grandes Jorasses and the North Face of the Drus (where his name is immortalised in the Fissure Lambert) put him at the forefront of international mountaineering; however, it was one climb in particular, in 1938, that gave Lambert true legendary status: a winter ascent of the Aiguilles Diables. Caught in a violent February storm, the climbing party found themselves stranded on the summit of Mont Blanc du Tacul. Lambert was the only one capable of contacting rescue. After three days sheltering in a crevasse, all of Lambert's toes were severely frostbitten. Subsequently, all of his toes were amputated.
