Günter Dyhrenfurth

Günter Oskar Dyhrenfurth (1886 to 1975) was a German-born, German and Swiss mountaineer, geologist and Himalayan explorer who won a gold medal in alpinism at the 1936 Summer Olympics, the third and final time the award was offered. He led the International Himalaya Expedition of 1930 to Kangchenjunga and that of 1934 to the Baltoro region of the Karakoram, which made the first ascent of Sia Kangri and explored the Gasherbrum group; the first ascent of Gasherbrum I in 1958 followed the route he had proposed. He compiled tables of High Asian mountains and, with Anders Bolinder, kept records of all major Himalayan expeditions, published in the Swiss journal Die Alpen and in the Berge der Welt year-books. His son Norman was also a mountaineer and an important expedition leader and film maker.
