The first four expeditions on Grand Combin reached only the minor summit east of Grand Combin (Aiguille du Croissant). The first one was made by mountain guides from the valley (Maurice Fellay and Jouvence Bruchez) on July 20, 1857. The first complete ascent of Grand Combin was finally made on July 30, 1859 by Charles Sainte-Claire Deville with Daniel, Emmanuel and Gaspard Balleys, and Basile Dorsaz.
