Oh Eun-sun

Oh Eun-sun (born 1966) is a South Korean mountaineer and the first South Korean woman to climb the Seven Summits. On 27 April 2010 she reached the summit of Annapurna, and on doing so she claimed to have climbed all fourteen eight-thousanders, which would have made her the first woman to achieve the feat. Her claim to have ascended Kangchenjunga was, however, disputed by multiple experts. Oh later admitted that she had stopped a few hundred metres before the summit of Kangchenjunga, and the Korean Alpine Federation ruled that she had not summited. The mountaineering site ExplorersWeb officially considers the Basque climber Edurne Pasaban the first woman to complete all fourteen.
