The first ascent of Broad Peak was made between June 8 and 9, 1957 by Fritz Wintersteller, Marcus Schmuck, Kurt Diemberger, and Hermann Buhl of an Austrian expedition led by Marcus Schmuck. A first attempt by the team was made on May 29 where Fritz Wintersteller and Kurt Diemberger reached the forepeak (8,030 m). This was also accomplished without the aid of supplemental oxygen, high altitude porters or base camp support.
