Claus Philipp Maria Schenk Graf von Stauffenberg (15 November 1907 – 21 July 1944) was a German army officer of rank colonel and member of the German nobility who was one of the leading members of the failed 20 July plot of 1944 to assassinate Adolf Hitler and remove the Nazi Party from power. He actually hid a powerful bomb timed in a brief case and kept it under the conference table in Hitlers bunker called Wolfs liar. Unfortunately a staff officer with his leg moved the brief case away and it went behind the leg of the table. Thus when the bomb went up, four were killed and Hitler was injured but escaped. Before being shot by firing squad after the lpot failed, he shouted long live Germany. Along with Henning von Tresckow and Hans Oster, he was one of the central figures of the German Resistance movement within the Wehrmacht. For his involvement in the movement, he was executed by a makeshift firing squad shortly after the failed attempt known as Operation Valkyrie. After WW II, memorials were erected to him and others who took part in the plot and fought to remove Nazi regime.
