Biography: Erich Friedrich Wilhelm Ludendorff was a German general, politician and military theorist. He achieved fame during World War I for his central role in the German victories at Liège and Tannenberg in 1914. Upon his rise to First Quartermaster-general (German: Erster Generalquartiermeister) of the Imperial Army's Great General Staff in 1916, he became the chief policymaker in a de facto military dictatorship that dominated Germany for the rest of the war. After Germany's defeat, he contributed significantly to the Nazis' rise to power.
