Einar Henry Gerhardsen was a Norwegian politician from the Labour Party of Norway. He was the 22nd prime minister of Norway for three periods, 1945–1951, 1955–1963 and 1963–1965. With a total of 16 years in office, he is the longest serving Prime Minister in Norway since the introduction of parliamentarism. Many Norwegians often refer to him as "Landsfaderen" ; he is generally considered one of the main architects of the post-war rebuilding of Norway after World War II. He also served as the second President of the Nordic Council in 1954.
