Achille Compagnoni

Italian mountain climber and skier (1914-2009)

On 31 July 1954, Achille Compagnoni became one of the first two individuals to reach the summit of K2. Born in Santa Caterina di Valfurva, Italy, in 1914, he balanced a career as a professional mountaineer, ski mountaineer, and biathlete, ultimately earning recognition as a Knight Grand Cross of the Order of Merit of the Italian Republic.

Early Career and Athletic Competition

Before his K2 ascent, Compagnoni established himself as a prominent skier. Serving with the Alpini corps of the Italian army, he secured a second-place finish in the fourth edition of the Trofeo Mezzalama alongside Lieutenant Giuseppe Lamberti and Sergeant Ettore Schranz. His competitive record in the Italian men's championships of cross-country skiing included a first-place finish in the 36 km race in 1940, alongside podium finishes in the 50 km and 18 km categories between 1939 and 1942.

The 1954 K2 Expedition

The successful 1954 summit expedition led by Ardito Desio remains the defining moment of his professional life. Compagnoni, accompanied by Lino Lacedelli, reached the peak at 18:10. To facilitate the climb, Walter Bonatti and Amir Mehdi ascended to 7,900 metres carrying supplemental oxygen bottles. The expedition became the subject of long-term controversy regarding the placement of the final camp and the exhaustion of the oxygen supply.

Post-Expedition Controversy

The events surrounding the night of the summit attempt involved a forced, dangerous bivouac for Bonatti and Mehdi. Compagnoni claimed the camp was moved to avoid an overhanging serac, while critics argued the move was intended to prevent Bonatti from joining the summit party. Following legal action in 1964, Bonatti was cleared of accusations regarding the oxygen usage. In 2008, the Club Alpino Italiano officially acknowledged the version of events presented by Bonatti.

Later Years and Legacy

Compagnoni authored accounts of his expeditions, including Uomini sul K2 and Il Tricolore sul K2, both published in 1958. His career spanned decades of Italian alpine history, reflected in his various appointments and awards. He lived the remainder of his life in Italy, eventually passing away in Aosta on 13 May 2009 at the age of 94.
