When was the first ascent of the Matterhorn’s North Face completed?

The first ascent of the Matterhorn’s North Face was completed on 1–2 August 1931 by the German brothers Franz and Toni Schmid. The route was a major milestone in technical Alpine climbing because the north face was far more difficult than the normal summit route. The Matterhorn’s North Face is one of the most famous walls in mountaineering history. The climb showed how rapidly alpine technique had advanced in the early 20th century. It remains a landmark achievement in climbing ethics and skill.
