President of Germany
Friedrich Ebert (SPD) served as Germany's first president, followed by Paul von Hindenburg. The office effectively came to an end upon Hindenburg's death in 1934 and its powers merged with those of chancellor. Adolf Hitler now ruled Germany as "Führer und Reichskanzler", combining his previous positions in party and government. The office, however, was not abolished and briefly revived at the end of the Second World War when Hitler appointed Grand Admiral Karl Dönitz as his successor as President of Germany. Dönitz agreed to the surrender to the Allies and was arrested a few days later.
Roman Herzog
Roman Herzog (5 April 1934 – 10 January 2017) was a German politician, judge and legal scholar, who served as President of Germany from 1994 to 1999.
