Norwegian explorer Roald Amundsen was born #OTD in 1872.
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 & 15 other men in the airship Norge became the first explorers verified to have reached the North Pole. He disappeared in June 1928 while flying on a rescue mission for the airship Italia in the Arctic.
