Benoît Chamoux

Benoît Chamoux (19 February 1961 – 6 October 1995) was a French Alpinist, who claimed to have summited 13 of the Eight-thousanders in the Himalayas.

Three of these climbs are disputed and are not formally recorded (Makalu in 1995, Cho Oyu in 1990 and Shishapangma in 1990). His official recorded number of ascents is 10.

Biography
Chamoux was born in La Roche-sur-Foron near Mont Blanc in the department of Haute-Savoie, France. He disappeared near the summit of his 14th Himalayan peak, Kangchenjunga (8586m) on 5 October 1995 with photographer Pierre Royer and their Sherpa Riku. Three of his eight-thousander ascents were to either their fore-summits or the plateau, and are disputed.

The non-profit "Foundation Benoît Chamoux" was created under the auspices of the Foundation of France with the mission to educate Sherpa children who have lost their fathers in mountain expeditions.
