Amundsen's South Pole expedition
The first expedition to reach the Geographic South Pole was led by the Norwegian explorer Roald Amundsen. He and four other crew members made it to the geographical South Pole on 14 December 1911, which was to be five weeks ahead of the British party led by Robert Falcon Scott as part of the Terra Nova Expedition.
