su StreamingCommunity. This episode is part of the series "The Conquerors of the Impossible (2/3)". From the 1950s to the 1980s, René Desmaison achieved a large number of "firsts". A specialist in normal routes (west face of Les Drus, Pilier du Freyney, Shroud...), he experienced a tragedy at the Grandes Jorasses, where his exceptional resistance allowed him to survive against all logic. He is the first to claim the practice of the mountain as a high level sport. A man of contrasts, his apparent strength hides great shyness and an unalterable enthusiasm despite the years. Beyond mountaineering, it is the spirit of adventure that has always inhabited him. A whole life devoted to mountaineering.
