Paul Caminada

Towards the end of the 19th century, engineering projects in mountainous regions suddenly took on a sensational character. At that time, such projects as the Gornergrat, Matterhorn and Jungfrau cable cars as well as probing the névé crest of Montblanc were the results of technology overcoming nature.

These projects entailed extensive explorations of the terrain at altitudes between 2,500 and 4,800 m above sea level using topographical plans as well as the corresponding tunneling in the ground, rock and glacier ice. The engineer's task was to determine the route between the two stations that could be soundly built with the least possible amount of materials and be operated safely.
