Hermann Hess Helfenstein

Hermann Hess Helfenstein (3 February 1916–14 October 2008) was a Swiss naturalist, explorer, climber and engineer.

He was member of the "Schweizer Alpen Club" (SAC in Switzerland) and "Deutscher Anden Verein" (DAV in Chile).

[4] Hermann Hess led and sponsored a 5-month expedition[5] to the Northern Patagonian Ice Field from 1 November 1941 to 1 March 1942, starting this time from the west with E. Hoffmann, J. Alig, G. Mani and the porter I. Vargas finding severe climatical and geographical difficulties.

[6][7] In that decade he made also the successful first climb with R. Eggmann and J. Neumeyer to isolated Cerro Maca in 1944.

He returned to Santiago, Capital of Chile, in 1963 and undertook the higher summits of the North Andes Mountain Range with members of DAV W. Foerster, F. Oestemer, H. Janko and other climbers until his death in 2008.
