Context paragraphs:
Johan Grøttumsbråten: Johan Hagbart Pedersen Grøttumsbraaten (12 February 1899 – 24 January 1983) was a Norwegian skier who competed in Nordic combined and cross-country.  Dominating both events in the 1920s and early 1930s, he won several medals in the early Winter Olympics.  Most notably, he won two gold medals at the 1928 Winter Olympics, and as one of the only two entrants to win two gold medalists from St. Moritz, was the most successful athlete there, along with Clas Thunberg of Finland.  He previously won three medals (one silver, two bronzes) at the inaugural Winter Olympics held in Chamonix in 1924, and went on to defend his Olympic Nordic Combined at the 1932 Winter Olympics.

Winter triathlon: Winter triathlon is a multisport event involving the continuous and sequential completion of running, mountain biking, and cross-country skiing, all on snow.  Course distances are set on the day of the event to achieve a winning time of around 80–90 minutes, after taking account of the snow conditions.

Louis Dufour: Louis Dufour (28 July 1901 – May 1960) was a Swiss ice hockey player who competed in the 1920 Summer Olympics, in the 1924 Winter Olympics, and in the 1928 Winter Olympics.  In 1920 he participated with the Swiss ice hockey team in the Summer Olympics ice hockey tournament.  Four years later he was also a member of the Swiss team in the first Winter Olympics tournament.  At the 1928 Olympics he won the bronze medal with the Swiss ice hockey team.

Clas Thunberg: Arnold Clas Robert Thunberg (5 April 1893 – 28 April 1973) was a Finnish speed skater who won five Olympic gold medals – three at the inaugural Winter Olympics held in Chamonix in 1924 (along with a silver and a bronze medal) and two at the 1928 Winter Olympics held in St. Moritz.  He was the most successful athlete at both of these Winter Olympics, sharing the honour for 1928 Winter Olympics with Johan Grøttumsbraaten of Norway.

List of Olympic medalists in skeleton: Skeleton is one of the Olympic sport disciplines contested at the Winter Olympic Games.  It was introduced at the 1928 Winter Olympics in St. Moritz – the birthplace of skeleton – in the form of a men's event contested over four runs.  Dropped from the 1932 and 1936 Winter Olympics program, skeleton returned in 1948, when St. Moritz hosted again the Winter Olympics, but was discarded from the following Games in Oslo.  After 54 years of absence from the Olympic program, skeleton was reinstated as an official medal sport at the 2002 Winter Olympics in Salt Lake City, featuring individual events for men and women.

1928 Winter Olympics medal table: The 1928 Winter Olympics medal table is a list of National Olympic Committee's nations ranked by the number of medals won during the 1928 Winter Olympics, held in St. Moritz, Switzerland from February 11 to February 19, 1928.  A total of 464 athletes from 25 countries participated in these Games, competing in 14 events in 6 disciplines.

Nordic Games: The Nordic Games was the first international multi-sport event that focused primarily on winter sports, and was held at varying intervals between 1901 and 1926.  It was organized by Sweden’s Central Association for the Promotion of Sports, and more specifically by Viktor Balck, a member of that association and one of the five original members of the International Olympic Committee.  It was, in many ways, a precursor to the modern Winter Olympic Games, whose success was a contributing factor (along with the social and economic turmoil following World War I) to the Nordic Games's discontinuation in the 1920s.

1928 Winter Olympics: The 1928 Winter Olympics, officially known as the II Olympic Winter Games (French: Les "IIes Jeux olympiques d'hiver") (German: "Olympische Winterspiele 1928") (Italian: "II Giochi olimpici invernali") (Romansch: "Gieus olimpics d'enviern 1928"), were a winter multi-sport event which was celebrated February 11–19, 1928 in St. Moritz, Switzerland.  The 1928 Games were the first true "Winter Olympics" held on its own as they were not in conjunction with a "Summer Olympics".  The preceding 1924 Games were retroactively renamed the inaugural Winter Olympics, though they had been in fact part of the 1924 Summer Olympics.  All preceding Winter Events of the Olympic Games were the winter sports part of the schedule of the Summer Games, and not held as a separate Winter Games.  These games also replaced the now redundant Nordic Games, that were held quadrennially since early in the century.

Sigmund Ruud: Sigmund Ruud (30 December 1907 – 7 April 1994) was a Norwegian ski jumper.  Together with his brothers Birger and Asbjørn, he dominated ski jumping in the 1920s and 1930s.  At the 1928 Winter Olympics in St. Moritz, Sigmund earned a silver medal.  At the 1929 FIS Nordic World Ski Championships, he won the ski jumping competition while earning a bronze at the 1930 event.  Sigmund also competed in the ski jumping competition at the Holmenkollen ski festival, which first began in 1933.  He also competed at the 1932 Winter Olympics in the ski jumping event, but finished seventh due to appendicitis.  Additionally, Sigmund wanted to compete in the first alpine skiing events at the 1936 Winter Olympics, though he did not start.

Skeleton at the Winter Olympics: Skeleton is a winter sport featured in the Winter Olympics where the competitor rides head-first and prone (lying face down) on a flat sled.  It is normally run on an ice track that allows the sled to gain speed by gravity.  It was first contested at the 1928 Winter Olympics in St. Moritz and again in 1948 Winter Olympics, after which it was discontinued as an Olympic sport.  Skeleton was reintroduced at the 2002 Winter Olympics, with both men's and women's events, and has been held in each Winter Olympic competition since.  Skeleton is so-named as the first metal sleds introduced in 1892 were said to resemble a human skeleton.
