Rudolf Christoph Freiherr von Gersdorff (27 March 1905 – 27 January 1980) was an officer in the German Army. He attempted to assassinate Adolf Hitler by suicide bombing on 21 March 1943; the plan failed when Hitler left early, but Gersdorff was undetected. That same month, soldiers from his unit discovered the mass graves of the Soviet-perpetrated Katyn massacre.
