Question: When was the King of Norway from 1957 until his death died who was awarded Holmenkollen Medal in 1968?
Context: Lauritz Bergendahl (30 January 1887 – 15 April 1964) was a Norwegian Nordic skier who won both the nordic combined and the 50 km cross country skiing events at the Holmenkollen ski festival in 1910, 1912, 1913, 1914, and 1915.  Bergendahl's Holmenkollen 50 km cross country skiing victories have only been exceeded by one skier (Thorleif Haug) while his Holmenkollen Nordic combined victories have been matched by three others (Johan Grøttumsbråten, Rauno Miettinen, and Bjarte Engen Vik).  Bergendahl earned the Holmenkollen medal in 1910 while his nephew Lars earned the honor in 1939. Bernt Assar Rönnlund (3 September 1935 – 5 January 2011) was a Swedish cross-country skier.  Rönnlund's biggest success was at the 1962 FIS Nordic World Ski Championships in Zakopane where he won two gold medals (15 km and 4 × 10 km) and a silver (50 km).  As a result, he earned the Svenska Dagbladet Gold Medal that year for his championship successes.  Rönnlund was the anchorman of the Swedish 4 × 10 km relay team at the 1964 Winter Olympics in Innsbruck, bringing the team from fourth place to victory.  Rönnlund also won the Vasaloppet in 1967 and the 50 km event at the Holmenkollen ski festival twice (1962 and 1968).  For his cross-country skiing successes, Rönnlund was awarded the Holmenkollen Medal in 1968 (shared with King Olav V, Gjermund Eggen and Bjørn Wirkola). Eero Johannes Kolehmainen (24 March 1918 – 7 December 2013) was a Finnish cross-country skier.  He competed in the 50 km event at the 1952 and 1956 Olympics and won a silver medal in 1952, placing fourth in 1956.  In 1957, aged 39, he won the 50 km races at the Holmenkollen ski festival and Lahti Ski Games.  The same year, he was awarded the Holmenkollen medal.  Kolehmainen's best finish at the FIS Nordic World Ski Championships was fifth over 50 km in 1958.  He was a farmer by occupation. Ole Martin Ellefsæter (born 15 February 1939) is a retired athlete from Norway.  He mostly competed in cross-country skiing, and won two gold medals at the 1968 Winter Olympics.  At the 1966 FIS Nordic World Ski Championships he won one gold (4×10 km) and one silver (15 km) medal, and in 1971 he became the first Norwegian to win Vasaloppet.  Anders Aukland and Jørgen Aukland are the only other Norwegians to win this ski race.  Earlier in 1967, Ellefsæter won the 50 km event at the Holmenkollen ski festival, the same year he was awarded the Holmenkollen medal, shared with Toini Gustafsson. Olav V (born Prince Alexander of Denmark; 2 July 1903 – 17 January 1991) was King of Norway from 1957 until his death. Astrid Sandvik (born 1 October 1939) is a Norwegian Alpine skier who finished tied for sixth place (with fellow Norwegian and 1958 Holmenkollen medalist Inger Bjørnbakken) in the women's slalom at the 1956 Winter Olympics in Cortina d'Ampezzo.  In 1963, Sandvik was awarded the Holmenkollen medal (shared with Alevtina Kolchina, Pavel Kolchin, and Torbjørn Yggeseth.) .  Sandvik is one of only eleven non-Nordic skiers to win the Holmenkollen medal (Stein Eriksen, King Haakon VII, Boghild Niskin, Inger Bjørnbakken, Sandvik, King Olav V, Erik Håker, Jacob Vaage, King Harald V, and Queen Sonja (all from Norway); and Ingemar Stenmark (Sweden) are the others.) . Arnfinn Bergmann (14 October 1928 – 13 February 2011) was a ski jumper from Norway.  He won the individual large hill event at the 1952 Olympics and 1952 Holmenkollen ski festival and placed third at the 1950 World Championships.  In 1956 he was awarded the Holmenkollen medal (shared with Borghild Niskin and Arne Hoel). Odd-Willy Martinsen (born 20 December 1942) is a retired Norwegian cross-country skier who competed during the 1960s and 1970s.  He won three medals at the Winter Olympics, a gold in the 4×10 km relay (1968) and silvers in the 30 km (1968) and the 4×10 km relay (1976).  Martinsen won five medals at the FIS Nordic World Ski Championships, a gold in the 4×10 km relay (1966), a silver in the 15 km (1970), and bronzes in the 15 km (1966), 30 km (1970), and 4×10 km relay (1974).  At the 1969 Holmenkollen ski festival, he won the 15 km race.  For his cross-country skiing successes in Norway and abroad, Martinsen received the Holmenkollen medal in 1969.  Thirty-two years later, his daughter, Bente Skari, received the Holmenkollen medal, making them the only father-daughter combination to ever win the prestigious honor. Elling Rønes (28 July 1882 – 12 September 1965) is a Norwegian cross country skier who won the men's 50 km event in 1906 (40 km), 1907, 1908, and 1916 at the Holmenkollen ski festival.  Born in Trysil, he was the first person to win the 50 km event at the Holmenkollen three times.  Rønes would be belatedly awarded the Holmenkollen medal in 1947. Gjermund Eggen (born 5 June 1941) is a retired Norwegian cross-country skier who won three gold medals at the 1966 FIS Nordic World Ski Championships.  The championships were held in Oslo in conjunction with the Holmenkollen ski festival, so Eggen's medals also counted as Holmenkollen victories.  He was awarded the Holmenkollen medal in 1968 (shared with King Olav V, Assar Rönnlund, and Bjørn Wirkola).  He competed at the 1968 Winter Olympics in the 30 km event, but finished only 34th.
