1955–58 Commonwealth Trans-Antarctic Expedition, Antarctic Plateau, Antarctica

In keeping with the tradition of polar expeditions of the 'heroic age' the CTAE was a private venture, though it was supported by the governments of the United Kingdom, New Zealand, United States, Australia and South Africa, as well as many corporate and individual donations, under the patronage of Queen Elizabeth II. It was headed by British explorer Dr Vivian Fuchs, with New Zealander Sir Edmund Hillary leading the New Zealand Ross Sea Support team. The New Zealand party included scientists participating in International Geophysical Year (IGY) research while the UK IGY team were separately based at Halley Bay.
Fuchs was knighted for his accomplishment. The second crossing of the continent did not happen until 1981, during the Transglobe Expedition led by Ranulph Fiennes.
