Mario Puchoz (pron. fr . AFI : [pyʃo] ) ( Courmayeur, 15 January 1918 – K2, 21 June 1954 ) was an Italian mountaineer.
Puchoz was born and lived in Courmayeur, at the foot of Mont Blanc. From a peasant family, he became passionate about the mountains, becoming a mountain guide.[1]
During the Second World War he was enlisted in the Alpine corps (Monte Cervino ski battalion), and participated in the Italian campaign in Russia in the Italian Expeditionary Force.[2][3]
After the war, Puchoz continued his activity as a mountaineer and mountain guide.
In 1953, he was summoned by Ardito Desio among the candidates to form the Italian expedition to attempt the first ascent of K2 in 1954; having passed the selections, Puchoz left with the other members of the expedition towards Pakistan.[4]
He participated with his other expedition companions in the preparation of the climbing route, the transport of materials and the establishment of the various base camps. On 18 June 1954, while he was at Camp II, at around 6,000 meters above sea level, Puchoz began to feel some discomfort, but it did not seem worried, and expressed the desire to remain at Camp II.[4][5] On 20 June, however, his condition suddenly worsened, and, despite the care of Dr. Guido Pagani, the expedition's doctor, Mario died at one in the morning on June 21.[4]
Dr. Pagani's diagnosis was fulminant pneumonia.[4] Today, in light of medical progress in general and knowledge of the problems of high altitude in particular, it is believed that the cause of Mario Puchoz's death was high altitude pulmonary edema.[6][7][8]
Due to bad weather, the expedition companions could not reach Camp II until July 26; Puchoz's body was recovered and transported to the base camp, where he was buried near Arthur Gilkey's tomb (where today the so-called Gilkey memorial stands).[4]
