The Grand Combin, which yields in height to only a few European mountains, was long one of the least known of Alpine summits. The first to commence the exploration of the great massif which separates the Val de Bagnes from the Val d'Entremont was Gottlieb Samuel Studer, of Berne, who on August 14, 1851 reached for the first time the summit of the Combin de Corbassière with the guide Joseph-Benjamin Fellay, and has published an account of that and a subsequent excursion in Bergund Gletscher-Fahrten. He was followed in that ascent five years later by W. and C. E. Mathews, and in 1857, William Mathews anticipated Studer in the ascent of the second peak of the Grand Combin.
