May 29 1953 is arguably the most important date in mountaineering history. At around 11:30am, Sherpa Tenzing Norgay and New Zealander Edmund Hillary became the first people to stand on the summit of the world’s highest mountain, Everest.
It’d be 22 years before Japanese mountaineer Junko Tabei would become the first woman to stand on the summit, which she achieved on May 16 1975. Three years later, Reinhold Messner and Peter Habeler became the first people to summit without supplemental oxygen, on May 8 1978. Fast forward to 2019, and it’s thought that a record 358 people reached the summit on a single day alone: May 23.
