Fridtjof Nansen
In the final decade of his life Nansen devoted himself primarily to the League of Nations, following his appointment in 1921 as the League's High Commissioner for Refugees. In 1922 he was awarded the Nobel Peace Prize for his work on behalf of the displaced victims of the First World War and related conflicts. Among the initiatives he introduced was the "Nansen passport" for stateless persons, a certificate recognised by more than 50 countries.
