Fridtjof Wedel-Jarlsberg Nansen was a Norwegian explorer, scientist, diplomat, humanitarian and Nobel Peace Prize laureate. In his youth he was a champion skier and ice skater. He led the team that made the first crossing of the Greenland interior in 1888, traversing the island on cross-country skis. He won international fame after reaching a record northern latitude of 86°14′ during his Fram expedition of 1893–1896. Although he retired from exploration after his return to Norway, his techniques of polar travel and his innovations in equipment and clothing influenced a generation of subsequent Arctic and Antarctic expeditions.
Nansen studied zoology at the Royal Frederick University in Christiania and later worked as a curator at the University Museum of Bergen where his research on the central nervous system of lower marine creatures earned him a doctorate and helped establish neuron doctrine. Later, neuroscientist Santiago Ramón y Cajal won the 1906 Nobel Prize in Medicine for his research on the same subject.
