Paul von Hindenburg
Hindenburg refused to sign this bill into law unless all Jewish veterans of World War I, Jewish civil servants who served in the civil service during the war and those Jewish civil servants whose fathers were veterans were allowed to stay in office. Hitler agreed, in order to get the law signed, even though he believed that the Jews had tried to undermine Germany during the Great War. It was Hindenburg who said that Germany lost the First World War because of politicians and others "stabbing the Army in the back". Hindenburg did not believe the story. He said it so that his wartime deputy Erich von Ludendorff would not write bad things in his memoirs. But Hitler did believe the story, and used it to gain power.
