Giusto Gervasutti, born on April 17, 1909, in Cervignano del Friuli and died on September 16, 1946, on Mont Blanc du Tacul, was an Italian mountaineer who opened numerous routes in the Alps, such as the northwest face of the Ailefroide and the Olan (considered at the time to be the biggest problem in the Alps after the Grandes Jorasses). Gervasutti discovered the mountains at a very young age in the Carnic Alps and the Dolomites, where he forged his temperament as a top-level mountaineer. At sixteen, he began climbing seriously, quickly linking increasingly challenging routes, and then settled in Turin in 1931, which definitively opened the door to major climbs in the Western Alps. His first significant achievements were the south face of the Marmolada and the first ascent of Monte Siera above Sappada, which established his skill on rock faces. In 1932, he discovered high-altitude winter climbing on the Nordend and the Matterhorn, laying the foundations for a style characterized by speed, commitment, and a quest for difficulty in the most challenging conditions. Very quickly, Gervasutti tackled the major problems of the era: in 1934, he opened the northwest face of the Olan, then considered one of the greatest alpine challenges after the Grandes Jorasses, followed by the northwest pillar of the Ailefroide Occidentale in 1936, often cited as one of the most beautiful lines in the Écrins massif. He also made the first ascent of the northeast couloir of Mont Blanc du Tacul and, with Boccalatte and other companions, established a series of pre-war routes that left a lasting mark on the Mont Blanc massif. Nicknamed "Il Fortissimo" for the physical and mental strength he displayed on the rock face, he combined technical mastery on rock, ice, and mixed terrain, a curiosity for modern equipment—particularly Vibram soles—and a keen sense of route finding that impressed his contemporaries. His masterpiece remains the first ascent of the east face of the Grandes Jorasses, achieved in 1942 with Giuseppe Gagliardone, while he was an officer during World War II. This route, long considered the most demanding in the Mont Blanc massif, crystallized his vision: a direct, committing climb where technical difficulty is compounded by extreme psychological exposure. Gervasutti died on September 16, 1946, on Mont Blanc du Tacul, the victim of a rappelling accident, leaving a legacy that extends far beyond his list of first ascents. His routes – Devies-Gervasutti on the Ailefroide, Gervasutti-Boccalette on the Gugliermina peak, the north pillar of the Frêney, the east face of the Grandes Jorasses – remain classics that still define high-level mountaineering. Giusto Gervasutti, a solitary and tormented mountaineer, endowed with an impeccable moral compass, an advocate of lightweight and ethical mountaineering, forever in pursuit of an unattainable happiness, is forever a legend of the mountains.
