The Ascent of the Jungfrau the 3rd August 1811

On the 29th July 1811, the brothers Johann Rudolf and Hieronymus Meyer from Aarau travelled across the Grimsel to the Lötschental. They reached, accompanied by the two chamois-hunters and mountaineers from the Valais Joseph Bortis and Alois Volken, a carrier from Guttannen, and three of their people from Aarau, the Great Aletsch firn on 1st August via the Lötschenlücke. They were equipped with food, wood, a foldable ladder, bars and ropes. The three porters were sent back, as they were too scary and unaccustomed to mountaineering. The others reached the foot of the Kranzberg, where they pitched their night camp.

The next day, early in the morning, they set out and ascended the Jungfraufirn. Since the glacier was severely jagged in some places, they had to use the ladder for the continuation. When they had the Jungfrau summit in front, a Föhn storm started and they had to return empty-handed.

The afternoon they used to explore the Ewig Schneefäld and the Grüneggfirn. Toward evening they pitched the night camp at the Mittelfluh, the southern foothills of the Trugberg. In the morning of the 3rd August, four of them started a new attempt to climb the Jungfrau. The four crossed the Jungfraufirn and ascended the steep and icy slopes to the Rotthalhorn. With the help of a rope, which they fastened to a stick pushed deep into the snow, they slid down the ice ridge to the Rotthalsattel and reached it at eight o'clock. Only with difficulty, half-seated, half climbing, they overcame the pointed ice ridge, which leads to the summit, looking left and right into the abyss. After crossing a deep firn crack, they stood on the summit at 2 o'clock in the afternoon.

Johann Rudolf Meyer (1739-1813) was not only an enthusiastic alpinist but also a successful silk band manufacturer. Together with the geometer Johann Heinrich Weiss, he published the "Atlas Suisse" between 1796 and 1802, the oldest map based on graphical triangulation covering the whole area of Switzerland. The Atlas contains 16 maps with a scale of 1: 120.000.
