Biographical Record & Archival Chronicle
Eugen Allwein was born on February 26, 1900, in Munich and combined a career in medicine with elite mountaineering. Partnering with Willo Welzenbach, Allwein made early landmark ascents in the Western Alps, including the daring 1926 first ascent of the sheer North Face of the Dent d'Hérens.
In 1928, Allwein served as expedition medical officer and lead climber on the landmark German-Soviet Alay-Pamir Expedition. Enduring brutal sub-zero gales and thin air on the high névé slopes, Allwein reached the 7,134-metre summit of Lenin Peak. He later served on the 1929 and 1931 German Kangchenjunga expeditions under Paul Bauer, pioneering high-altitude physiological research and extreme ridge climbing in the Himalaya.

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.
