Germain Sommeiller died in his native town of Saint-Jeoire on July 11, 1871. Pointe Sommeiller, a 3332-meter-high peak in the Cottian Alps, and Col Sommeiller, the nearby mountain pass linking Bramans, France to Bardonecchia, Italy, were named in his honour. Several streets in Savoy cities such as Annecy also bear Sommeiller's name.
