[4] The two Austrians, Rainer and Angerer, also a member of the SA, knew that the German duo, Max Sedlmayer and Karl Mehringer had spent a long time on the First Band during their fatal attempt in 1935.

[6] The German pair were the first to reach a difficult section that required a pendulum action, called a tension traverse, to get across the steep rock face.

[7] At this stage the four climbers combined into one team and continued their ascent to the "Death Bivouac", where Sedlmayer and Mehringer were last seen from Kleine Scheidegg the previous year.

[8] The following day Kurz died almost within reach of a rescue team but for his inability to pass the knotted abseil rope, that had been dropped down by rescuers, through a carabiner with his frozen fingers.

[7] The climb is recalled in the 2007 drama documentary The Beckoning Silence inspired by climber Joe Simpson's book of the same name[9] and again in the 2008 feature film North Face directed by Philipp Stölzl.
