The first siblings to conquer all 14 mountains over 8,000 m (26,246 ft) are brothers Mingma and Chhang Dawa Sherpa (Nepal). Mingma completed his climbs between 2000 and 2011, and Dawa completed his between 2001 and 2013.
Both brothers used supplementary oxygen for only the four highest mountains. They now operate the expedition firm Seven Summits Treks, organizing supported climbs and treks throughout Nepal, Pakistan and China.
