Roald Engelbregt Gravning Amundsen (, ; ; 16 July 1872 – ) was a Norwegian explorer of polar regions. He was a key figure of the period known as the Heroic Age of Antarctic Exploration. Born in Borge, Østfold, Norway, Amundsen began his career as a polar explorer as first mate on Adrien de Gerlache's Belgian Antarctic Expedition of 1897–1899. From 1903 to 1906, he led the first expedition to successfully traverse the Northwest Passage on the sloop Gjøa. In 1909, Amundsen began planning for a South Pole expedition. He left Norway in June 1910 on the ship Fram and reached Antarctica in January 1911. His party established a camp at the Bay of Whales and a series of supply depots on the Barrier (now known as the Ross Ice Shelf) before setting out for the pole in October. The party of five, led by Amundsen, became the first to successfully reach the South Pole on 14 December 1911. Following a failed attempt in 1918 to reach the North Pole by traversing the Northeast Passage on the ship Maud, Amundsen began planning for an aerial expedition instead. On 12 May 1926, Amundsen and 15 other men in the airship Norge became the first explorers verified to have reached the North Pole. Amundsen disappeared in June 1928 while flying on a rescue mission for the airship in the Arctic. The search for his remains, which have not been found, was called off in September of that year. Early life Amundsen was born into a family of Norwegian shipowners and captains in Borge, between the towns Fredrikstad and Sarpsborg. His parents were Jens Amundsen and Hanna Sahlqvist. Roald was the fourth son in the family. His mother wanted him to avoid the family maritime trade and encouraged him to become a doctor, a promise that Amundsen kept until his mother died when he was aged 21. He promptly quit university for a life at sea. When he was fifteen years old, Amundsen was enthralled by reading Sir John Franklin's narratives of his overland Arctic expeditions. Amundsen wrote "I read them with a fervid fascination which has shaped the whole course of my life".

This expedition, led by Adrien de Gerlache using the ship the RV Belgica, became the first expedition to
