The Nazi War Criminals - Rudolph Hess 

Hess was an early member of the Nazi Party and served as Hitler's deputy after the Nazis gained power. During the night of May 10, 1941 Hess piloted a German fighter plane over England and parachuted to earth with the intention of opening peace negotiations with the British. He was immediately imprisoned in the Tower of London where he remained for the rest of the war. He was convicted of conspiracy to commit crimes and crimes against peace and sentenced to life in prison. He served the majority of his sentence in Berlin's Spandau Prison and after 1966 was its only prisoner. He died in 1987 while in captivity.
