Claus von Stauffenberg, German soldier who attempted to assassinate Adolf Hitler (born 1907)

Claus Philipp Maria Justinian Schenk Graf von Stauffenberg was a German army officer who is best known for his failed attempt on 20 July 1944 to assassinate Adolf Hitler at the Wolf's Lair, part of Operation Valkyrie, a plan that would have seen the arrest of Nazi leadership in the wake of Hitler's death and an earlier end to World War II.

The 20 July plot, sometimes referred to as Operation Valkyrie, was a failed attempt to assassinate Adolf Hitler, the chancellor of Germany, and overthrow the Nazi regime on 20 July 1944. The plotters were part of the German resistance, mainly composed of Wehrmacht officers. The leader of the conspiracy, Claus von Stauffenberg, tried to kill Hitler by detonating an explosive hidden in a briefcase. However, due to the location of the bomb at the time of detonation, the blast only dealt Hitler minor injuries. The planners' subsequent coup attempt also failed and resulted in a purge of the Wehrmacht.
