Otto Bauer, Austrian philosopher and politician, Foreign Minister of Austria (died 1938)

Otto Bauer was an Austrian politician who was one of the founders and leading thinkers of the Austromarxists who sought a middle ground between social democracy and revolutionary socialism. He was a member of the Austrian Parliament from 1907 to 1934, deputy party leader of the Social Democratic Workers' Party (SDAP) from 1918 to 1934, and Foreign Minister of the Republic of German-Austria in 1918 and 1919. In the latter position, he worked unsuccessfully to bring about the unification of Austria and the Weimar Republic. His opposition to the SDAP joining coalition governments after it lost its leading position in Parliament in 1920 and his practice of advising the party to wait for the proper historical circumstances before taking action were criticized by some for facilitating Austria's move from democracy to fascism in the 1930s. When the SDAP was outlawed by Chancellor Kurt Schuschnigg in 1934, Bauer went into exile, where he continued to work for Austrian socialism until his death.
