Hermann Kümmerly (1857–1905) studied Painting and was trained as a map painter. In 1884 he overtook the paternal company together with his brother Arnold. His relief map of Evolena–Zermatt–Monte Rosa (1891) in the SAC’s yearbook was seminal; Rudolf Leuzinger etched the map. Kümmerly became famous for his Swiss school wall map with modern relief depiction (1896). He and his brother-in-law Julius Frey, who joined the company as co-partner in 1898, thus rendered the company “Kümmerly+Frey” to the leading producer of school wall maps. The school wall map of the Canton of Grisons (1902) is an especially beautiful example of felicitous relief depiction.
