When did Sir Vivian Fuchs and Sir Edmund Hillary lead the first expedition to cross Antarctica by land?
“The 1955–58 Commonwealth Trans-Antarctic Expedition (CTAE) was a Commonwealth-sponsored expedition that successfully completed the first overland crossing of Antarctica, via the South Pole. The expedition was funded by the governments of the United Kingdom, New Zealand, Australia and South Africa, as well as private and corporate donations, under the patronage of Queen Elizabeth II. It was headed by British explorer Dr Vivian Fuchs, with New Zealander Sir Edmund Hillary leading a supply support team.
