Annapurna I (8,091 m; 26,545 ft) is the 10th highest mountain in the world and the first of the eight-thousanders – the 14 mountain that stand taller than 8,000 metres – to have been successfully climbed, on 3 June 1950, by Maurice Herzog and Louis Lachenal (both France). As of 31 January 2018, only 251 people had successfully reached the top of Annapurna in 261 ascents (fewer than any other eight-thousanders), and 69 people died – 11 of them on the way back from the top. No other eight-thousander is deadlier: for every three climbers who make it safely up and down Annapurna I, one dies trying (27.6 percent).
