Oh Eun-sun, South Korean mountaineer
Oh Eun-sun (Korean: 오은선, Hanja: 吳銀善, born March 5, 1966) is a South Korean mountaineer. She was the first Korean woman to climb the Seven Summits. On April 27, 2010, she reached the summit of Annapurna; upon doing so, she claimed to have climbed all fourteen eight-thousanders, which would have made her the first woman to achieve this feat. However, her claim to have ascended Kangchenjunga was disputed by multiple experts. Oh later admitted that she had stopped a few hundred meters before the summit of Kangchenjunga, and so the Korean Alpine Federation ruled that she had not summited. The mountaineering site ExplorersWeb considered Edurne Pasaban as the first woman to have successfully climbed all fourteen peaks.
