Müller, Hermann (hĕrˈmän mülˈər) [key], 1876–1931, German statesman. A Social Democrat, he succeeded in 1919 to the post of German foreign minister and signed the Treaty of Versailles. He was chancellor in 1920 and again from 1928 to 1930. During the second tenure Germany accepted the Kellogg-Briand Pact and the Young Plan. Largely because of the diplomatic efforts of Müller's foreign minister, Gustav Stresemann, the occupation of the Rhineland was ended in 1929. Müller's cabinet was the last parliamentary government of the Weimar Republic. He was succeeded by Heinrich Brüning.
