Biographical Record & Archival Chronicle
Karl Wien was born on September 10, 1906, in Würzburg and studied physics and geography under Professor Willi Rickmer Rickmers at the University of Munich. A gifted alpinist from an early age, Wien was a core member of the Academic Alpine Club of Munich (AAVM), completing daring technical first ascents across the Bavarian Alps, Dolomites, and Western Alps.
In 1928, at just twenty-two years of age, Wien joined the joint German-Soviet Alay-Pamir Expedition. On September 25, 1928, alongside Eugen Allwein and Erwin Schneider, Wien stood on the summit of Lenin Peak (7,134 m), establishing a new world altitude record for a climbed peak. In 1937, Wien was selected as the overall leader of the German Nanga Parbat expedition, where he and fifteen teammates tragically perished in a colossal ice avalanche at Camp IV on June 15, 1937.

Lenin Peak / Ibn Sina Peak
Lenin Peak (officially Ibn Sina Peak in Tajikistan) is a colossal glaciated mountain rising to 7,134 metres (23,406 ft) on the border of Kyrgyzstan and Tajikistan in the Trans-Alay Range of the northern Pamirs. Famous for its massive non-technical snow slopes and broad summit plateau, it was first conquered during the 1928 German-Soviet Alay-Pamir Expedition by Karl Wien, Eugen Allwein, and Erwin Schneider, setting an international altitude record for that era. Today, it is revered as the world's most climbed and accessible 7,000-metre peak.

Lenin Peak Razdelnaya Route & West Ridge
The Razdelnaya Route via the North Face and West Ridge is the classic standard route on Lenin Peak (7,134 m). Starting from the Achik-Tash Base Camp (3,600 m), the route navigates the crevassed Lenin Glacier to Camp 2 (5,300 m), scales the steep snow slopes to Razdelnaya Peak (6,148 m) for Camp 3, and makes a sustained 1,000-metre summit push along the exposed West Ridge to 7,134 metres.
