Erich Friedrich Wilhelm Ludendorff (9 April 1865 – 20 December 1937) was a German general, politician, and military theorist. He first achieved fame during World War I for his role in German victories on the Easter Front. He later had a large influence on Germany policy in general during the later years of World War I. In the postwar period, he had various involvements in German nationalism, including as a participant in the Munich Putsch. In his later years, he separated from the NSDAP and was influenced by the views of his second wife, Mathilde Ludendorff.
