Ueli Steck (born October 4, 1976, in Langnau in Emmental, Switzerland) is a Swiss climber. He is also a skilled carpenter and lives in Ringgenberg in Interlaken. At the age of 17, Steck achieved the 9th difficulty rating (UIAA) in climbing. As an 18-year-old, he climbed the north face of the Eiger and the Bonatti Pillar in the Mont Blanc massif. In June 2004, he climbed the Eiger, Mönch, and Jungfrau within 25 hours with Stephan Siegrist. Another success was the so-called Khumbu-Express in 2005, for which the climbing magazine Climb named him one of the three best alpinists in Europe. The project consisted of the first solo climb of the north wall of Cholatse (6440 m) and the east wall of Taboche (6505 m).
