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 6 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.
