Karl Renner, Austrian lawyer and politician, 4th President of Austria (d. 1950)

Karl Renner (14 December 1870 – 31 December 1950) was an Austrian politician of the Social Democratic Workers' Party of Austria. He is often referred to as the "Father of the Republic" because he led the first government of German-Austria and the First Austrian Republic in 1919 and 1920, and was once again decisive in establishing the present Second Republic after the fall of Nazi Germany in 1945, becoming its first President after World War II (and fourth overall).
