Dr Paul Güssfeldt (spelled Güßfeldt in German) (14 October 1840 – 18 January 1920) was a German geologist, mountaineer and explorer.
Güssfeldt was born in Berlin, where he also died almost 80 years later. After attending the Collège Français in his home city, he studied natural sciences and mathematics in Heidelberg (where he joined the Vandalia student corps), from 1859 to 1865, and then in Berlin, Gießen and Bonn.
He made several first ascents in the Alps, including Piz Scerscen with Hans Grass and Caspar Capat on 13 September 1877 via the north-west spur (the Eisnase route). He made winter ascents of the Grandes Jorasses and the Gran Paradiso, as well as putting up several new routes on Mont Blanc, including the Peuterey ridge on 15–19 August 1893 (with Emile Rey, Christian Klucker and César Ollier). Pointe Güssfeldt (4,112 m), the highest summit on the Aiguille Blanche de Peuterey is named after him, as is the Güssfeldtsattel, the col between Piz Scerscen and Piz Roseg also known as the Porta da Roseg. This steep ice slope was first climbed by Güssfeldt with guides Hans Grass, Peter Jenny and Caspar Capat on 13 September 1872.
In 1883 Güssfeldt made the first attempt on Aconcagua by a European. Bribing porters with the story that there was treasure on the mountain, he approached Aconcagua via the Rio Volcan, making two attempts on the peak by the north-west ridge and reaching an altitude of 6,500 metres. The route that he prospected is now the normal route up the mountain.
Between 1889 until 1914 Güssfeldt was invited by the German Emperor Wilhelm II to join him for his annual summer cruise in the North Sea, which Güssfeldt was given the responsibility of planning as well. The emperor was fond of Güssfeldt and wrote about him in his memoirs.[1]
