Edouard Wyss-Dunant, was appointed leader of this expedition. All the expedition’s participants were from Geneva, they almost all belonged to the exclusive «L'Androsace» climbing club and knew each other very well. The city and Canton of Geneva provided moral and financial support for the expedition, and the University of Geneva provided the scientific contingent.

The mountaineering task that this team had set itself was primarily exploring the access to the South Col

.

The results of this first Swiss Everest expedition are remarkable, and exceeded even the most optimistic expectations. At the first attempt, they had opened up a new route to Everest, and had reached an extraordinary height on the south-western ridge in difficult conditions. In the opinion of the extremely critical Marcel Kurz, this expedition could almost be compared to a victory. It paved the way for further successes by other expeditions.
