North Pole, northern end of the earth's axis, lat. 90°N. It is distinguished from the north magnetic pole. U.S. explorer Robert E. Peary is traditionally credited as being the first to reach (1909) the North Pole. In 1926, Richard E. Byrd and Floyd Bennett may have been the first persons to fly over the pole, but entries in Byrd's diary suggest that they may have missed the actual pole; if so, that feat would belong to Roald Amundsen.
