Alison Hargreaves

Alison Jane Hargreaves was a British mountaineer. Her accomplishments included scaling Mount Everest alone, without supplementary oxygen or support from a Sherpa team, in 1995. She soloed all the great north faces of the Alps in a single season—a first for any climber. This feat included climbing the difficult north face of the Eiger in the Alps. Hargreaves also climbed 6,812-metre (22,349 ft) Ama Dablam in Nepal.
