query: Who was the first leader of West Germany?
passage: Theodor Heuss
Theodor Heuss (German pronunciation:[ˈte:odɔɐ ˈhɔʏs]; 31 January 1884 – 12 December 1963) was a West German liberal politician who served as the first President of the Federal Republic of Germany from 1949 to 1959. Beside the stern chancellor Konrad Adenauer, Heuss' cordial manners largely contributed to the stabilization of democracy in West Germany during the Wirtschaftswunder years.
passage: President of Germany
If the president dies, resigns or is otherwise removed from office, a successor is to be elected within thirty days. Horst Köhler, upon his resignation on May 31, 2010, became the first president to trigger this re-election process. Jens Böhrnsen, President of the Senate and Mayor of the Free Hanseatic City of Bremen and at the time President of the Bundesrat, assumed the powers and duties of head of state.[22] Similarly, when Christian Wulff resigned in 2012, it was Horst Seehofer, Minister-President of Bavaria, as President of the Bundesrat, who assumed the powers and duties of head of state. When Heinrich Lübke, on the other hand, announced his resignation in 1968, it only came into effect the following year, a mere three months before the scheduled end of his term and after the expedited election of his successor. Back in 1949 Karl Arnold, at the time Minister-President of North Rhine-Westphalia and President of the Bundesrat, also acted as head of state for a few days: after the Basic Law had come into effect and he himself was elected as President of the Bundesrat, the first President of Germany was not yet elected and the office therefore vacant.
