Background
Ollenhauer was born in Magdeburg and joined the Social Democratic Party of Germany in 1920.
Ollenhauer was born in Magdeburg and joined the Social Democratic Party of Germany in 1920.
When the Nazis took power in 1933 he fled Germany for Prague. After the outbreak of WW2 Ollenhauer travelled across Europe in order to avoid Nazi persecution, first going to Denmark, then France, Spain, Portugal, and eventually London, where he remained until the end of the war. In London, he kept close ties to the Labour Party, which financially supported the expatriate Social Democratic Party of Germany (called SoPaDe), of which Ollenhauer was a member.
In February 1946, Ollenhauer returned to Germany.
In May the same year, he was voted deputy leader of the Social Democratic Party of Germany, behind Kurt Schumacher. Ollenhauer entered the Bundestag after the 1949 German federal elections.
After Schumacher"s unexpected death in 1952, the Social Democratic Party of Germany elected Ollenhauer as its leader. He ran as the Social Democratic Party of Germany"s candidate for Chancellor of Germany in the 1953 and 1957 German elections, both of which were lost to Konrad Adenauer"s Christian Democratic Union. While the plan was denounced as radical at the time, it helped pave the way for Willy Brandt"s Ostpolitik, as well as indirectly influencing some developments within the European Union, such as a European common security policy) and the eventual reunification of Germany.
Ollenhauer"s proposal is also known as the Ollenhauer Plan.
In 1961, Ollenhauer declined to run for Chancellor a third time, instead supporting the candidacy of Berlin mayor Willy Brandt. Ollenhauer died in Bonn on 14 December 1963.
He also worked with the Union of German Socialist Organisations in Great Britain.
