Background: Hillary was born to Percival Augustus and Gertrude (nee Clark) Hillary in Auckland, New Zealand, on 20 July 1919. His family moved to Tuakau, south of Auckland, in 1920, after his father, who served at Gallipoli with the 15th (North Auckland) Regiment, was allocated land there. His grandparents had emigrated from Yorkshire to northern Wairoa in the mid-19th century.
Context: Hillary climbed ten other peaks in the Himalayas on further visits in 1956, 1960-1961, and 1963-1965. He also reached the South Pole as part of the Commonwealth Trans-Antarctic Expedition, for which he led the New Zealand section, on 4 January 1958. His party was the first to reach the Pole overland since Amundsen in 1911 and Scott in 1912, and the first ever to do so using motor vehicles.  In 1960 Hillary organized an expedition to search for the fabled abominable snowman. Hillary was with the expedition for five months, although it lasted for ten. No evidence of Yetis was found, instead footprints and tracks were proven to be from other causes. During the expedition, Hillary travelled to remote temples which contained "Yeti scalps"; however after bringing back three relics, two were shown to be from bears and one from a goat antelope. Hillary said after the expedition: "The yeti is not a strange, superhuman creature as has been imagined. We have found rational explanations for most yeti phenomena".  In 1962 he was a guest on the television game show What's My Line?; he stumped the panel, comprising Dorothy Kilgallen, Arlene Francis, Bennett Cerf, and Merv Griffin. In 1977, he led a jetboat expedition, titled "Ocean to Sky", from the mouth of the Ganges River to its source. From 1977 to 1979 he commentated aboard Antarctic sightseeing flights operated by Air New Zealand. In 1985, he accompanied Neil Armstrong in a small twin-engined ski plane over the Arctic Ocean and landed at the North Pole. Hillary thus became the first man to stand at both poles and on the summit of Everest. This accomplishment inspired generations of explorers to compete over what later was defined as Three Poles Challenge. In January 2007, Hillary travelled to Antarctica as part of a delegation commemorating the 50th anniversary of the founding of Scott Base.
