Answer the question at the end by quoting:

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.
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.

Did Edmund explore anywhere else after that expedition?

In 1977, he led a jetboat expedition, titled "Ocean to Sky", from the mouth of the Ganges River to its source.

Some context: Louis "Louison" Bobet (pronounced [lwi.zo bo.be]; 12 March 1925 - 13 March 1983) was a French professional road racing cyclist. He was the first great French rider of the post-war period and the first rider to win the Tour de France in three successive years, from 1953 to 1955. His career included the national road championship (1950 and 1951), Milan-San Remo (1951), Giro di Lombardia (1951), Criterium International (1951 & 52), Paris-Nice (1952), Grand Prix des Nations (1952), world road championship (1954), Tour of Flanders (1955), Criterium du Dauphine Libere (1955), Tour de Luxembourg (1955), Paris-Roubaix (1956) and Bordeaux-Paris (1959).
Louis Bobet was born one of three children above his father's baker's shop in the rue de Montfort, Saint-Meen-le-Grand, near Rennes. His father gave him a bicycle when he was two and after six months he could ride it 6 km. Bobet's father was also called Louis and the son was called Louison - little Louis - to avoid confusion The ending -on is a diminutive in French but outside Brittany Louison refers more usually to a girl. He was known as Louis in his early years as a rider, even as a professional, until the diminutive Louison gained in popularity.  His sister played table tennis, his brother Jean football, although he also became a professional cyclist. Louison played both table tennis and football and became Brittany champion at table tennis. It was his uncle, Raymond, who was president of a cycling club in Paris who persuaded him to concentrate on cycling.  Bobet's first race was a 30 km event when he was 13. He came second in a sprint finish. He raced in his local area and won four events for unlicensed riders in 1941. He qualified for the final of the unofficial youth championship, the Premier Pas Dunlop in 1943 at Montlucon and came sixth. The winner was Raphael Geminiani, who would become a professional team-mate and rival.  Bobet is said to have carried messages for the Resistance during the second world war. After D-Day he joined the army and served in eastern France. He was demobilised in December 1945.
Does he have a sister?

IN: Backlund was born in Princeton, Minnesota, in 1949. During his freshman year, Backlund was an All-American in both football and wrestling (191 lb [87 kg], finishing third) while at Waldorf Junior College in Forest City, Iowa. During his sophomore campaign, Backlund focused on wrestling and once again earned All American Honors (190 lb [86 kg] and national runner-up). Backlund was an amateur wrestler at North Dakota State University, winning the Division II NCAA Championship at 190 pounds in 1971.

After having been popular with the fans from early on, in the final months of his title reign, Backlund changed his image, cutting his moppish hair into a crewcut, wearing amateur wrestling singlets and losing muscle mass and definition. Fans seemingly grew weary of this "Howdy Doody" character (as The Grand Wizard had dubbed him). In 1983, he was voted the Wrestling Observer Newsletter's Most Overrated Wrestler. Vincent K. McMahon, who had bought the WWF from his father, wanted to put the title on the more charismatic and muscular Hulk Hogan. McMahon initially suggested Backlund to turn heel and lose to Hogan, but when Backlund refused, a transitional champion became necessary between Backlund and Hogan. Backlund sustained a (kayfabe) injury when The Iron Sheik assaulted him with his Persian clubs and on December 26, 1983, Backlund lost the title to Sheik when Backlund's manager, Arnold Skaaland, threw in the towel while Backlund was locked in the camel clutch.  Due to Backlund's (kayfabe) injury, Hogan took over Backlund's rematch and became the new WWF World Heavyweight Champion. However, this was a television storyline only; Backlund wrestled The Iron Sheik at least three times for the title, all at non-televised house shows (including once at the Boston Garden, winning by disqualification), and also wrestled The Magnificent Muraco for the Intercontinental Heavyweight Championship, also at a non-televised house show.  Backlund continued to work for the WWF for a while after the title change, but did not receive another title shot for the WWF World Heavyweight Championship after Hogan's victory. On August 4, 1984, Backlund defeated Salvatore Bellomo in his last WWF match for 8 years.

What was his image change?
