BERLIN -- As a 22-year-old German army lieutenant, Ewald-Heinrich von Kleist volunteered to wear a suicide vest to a meeting with Adolf Hitler and to blow himself up along with the Nazi dictator. The assassination didn't come to pass, but von Kleist went on to play a key role in the most famous attempt on Hitler later that same year, and was the last surviving member of the group of German officers who tried and failed to kill the Fuehrer on July 20, 1944.
