Claus Schenk Graf von Stauffenberg

Claus Philipp Maria Schenk Graf von Stauffenberg (15 November 1907 – 21 July 1944) was a German army officer best known for his failed attempt on 20 July 1944 to assassinate Adolf Hitler at the Wolf's Lair and remove the Nazi Party from power. Along with Henning von Tresckow and Hans Oster, he was one of the central figures of the German resistance to Nazism within the Wehrmacht. For his involvement in the movement, he was executed by firing squad shortly after Operation Valkyrie.
