John Crabbe Cunningham

John Crabbe Cunningham (23 November 1927 – 31 January 1980) was a Scottish climber. Born in Glasgow, he was a member of the Creagh Dhu Mountaineering Club and climbed extensively in the Scottish mountains, where he pioneered new techniques of ice climbing.

During the 1950s and 1960s, Cunningham went to New Zealand, India, South Georgia and Antarctica. He wanted to climb Mount Everest, and in 1953 he had gone to Nepal via India with Hamish MacInnes, also a Scottish mountaineer, to start his climb. However, Hillary and Tenzing had made it to the top of Mount Everest before he could begin.

On 23 November 1964, he made the first ascent of Antarctica's Mount Jackson.
