Finnish speed skater nicknamed 'Nurmi on Ice,' who dominated the sport's first two Winter Olympics and holds a men's record of five Olympic gold medals that stood unmatched for over half a century.

Arnold Clas Robert Thunberg was born on 5 April 1893 in Helsinki, Finland, and led a somewhat rowdy early life as a compulsive smoker and drinker before turning to speed skating in earnest at 18. He didn't compete internationally until age 28, making his debut at the 1922 World Allround Championships, but quickly became the sport's dominant force for the following decade. At the inaugural 1924 Winter Olympics in Chamonix, Thunberg won three gold medals - the 1,500m, 5,000m, and the combined all-around event - plus a silver in the 10,000m and bronze in the 500m, making him the most decorated athlete of the Games and earning him the nickname 'Nurmi on Ice,' after Finland's legendary distance runner Paavo Nurmi. He returned at the 1928 St. Moritz Olympics to win two more golds - defending his 1,500m title and sharing the 500m gold with Norway's Bernt Evensen - becoming, at 34, the oldest Olympic speed skating champion at the time. Thunberg won five World Allround Championship titles between 1923 and 1931 and four European titles, but at age 39, in peak condition for the 1932 Lake Placid Olympics, he withdrew in protest of the newly introduced American 'pack style' mass-start racing format, a stance shared by several leading European skaters. It proved to be his final Olympics. His five Olympic gold medals across two Games remained the record for men's speed skating until Eric Heiden matched it in a single Olympics in 1980, and his seven total Winter Games medals remain a speed skating record to this day. He later served in the Finnish parliament.
