The first ascent of Broad Peak was made between June 8 and 9, 1957, by Fritz Wintersteller, Marcus Schmuck, Kurt Diemberger, and Buhl of an Austrian expedition led by Schmuck. A first attempt by the team had been made on May 29, when Fritz Wintersteller and Kurt Diemberger reached the forepeak (8030 m). This was also accomplished without the aid of supplemental oxygen, high-altitude porters or base camp support.
