Answer
The answer is November. Stauffenberg, the key figure in the failed 20 July plot to assassinate Adolf Hitler, was born on November 15, 1907, in Jettingen, Germany. His full name is Claus Schenk Graf von Stauffenberg. He came from a noble Catholic family with a long history of military service. Stauffenberg's opposition to Hitler grew during World War II as he witnessed the atrocities committed by the Nazi regime.
