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. This expedition was done without the use of supplemental oxygen, which help climbers breath at high altitudes. Thomas George Montgomery, a British surveyor, named the mountain K3 in 1856 and Martin Conway gave it the name Broad Peak for its mile long summit ridge in 1892.
