After his father's assassination attempt against Adolf Hitler failed on 20 July 1944, Stauffenberg was sent to a foster home in Bad Sachsa and given the new surname of "Meister", as the Nazis viewed the name of Stauffenberg unacceptable, due to the prominence of that name in the assassination attempt. Franz-Ludwig's mother, two older brothers, and younger sister Valerie, as well as other relatives, were arrested under Nazi "Sippenhaft" (blood guilt) laws. He was educated at the Schule Schloss Salem and then qualified as a lawyer after passing his "staatsexamen".
