[3][4] She grew up in Frankfurt before attending an all-girls boarding school near Lake Geneva.
[6] On 27 July of that year, she and Max Helff, Günter von Saar, Helene Wirthl, and Richard Witzenböck were the first to ascend the Tricot ridge of the Aiguille de Bionnassay.
[7] In 1919, she descended Monte Rosa after reaching its summit, becoming the first woman to climb its east face.
[5] On 18 August 1925, Noll-Hasenclever, Hans Pfann, and Hermann Trier climbed the Weisshorn, and during their descent of the nearby Bishorn, an avalanche swept over them and carried them down to the Bies Glacier, trapping Noll-Hasenclever and Pfann.
[3][5][1] She was buried in Zermatt in a section of the graveyard known as the "Mountaineers' Cemetery", which mainly holds people who died climbing local peaks.
