Jean-Baptiste d'Autriche
The ascent by Joseph Anton Specht from Vienna, guided by Leander and Nicodem Klotz from Vent in 1861, was and is usually considered the first. However, personal notes of Archduke John of Austria about his excursion over the Niederjoch from Vent to Schnals in the summer of 1846, made public in 1903, suggest that his guides, Johann Gurschler and Josef Weitthalm from Schnals, had climbed the mountain the previous summer.
