Raymond Lambert (18 October 1914 - 24 February 1997) was a Swiss mountaineer who together with Sherpa Tenzing Norgay reached an altitude of 8611 metres (just 237 metres from the summit) of Mount Everest, as part of a Swiss Expedition in May 1952. At the time it was the highest point that a climber had ever reached. There was a second Swiss expedition in autumn 1952, but a party including Lambert and Tenzing was forced to turn back at a slightly lower point. The following year Tenzing returned with Edmund Hillary to reach the summit on 29 May 1953.
