Hans Speidel was a German general during World War II and the Cold War. The former chief of staff to Field Marshal Erwin Rommel, Speidel was a nationalist conservative who agreed with the territorial aspects of the Nazi regime's policies, but strongly disagreed with their racial policies. This led him to participate in the July 20 Plot to assassinate Hitler, after which he was jailed by the Gestapo. At the end of the world war, he escaped from Nazi prison and went into hiding.
After the world war, Speidel emerged as one of the leading German military figures during the early Cold War. He served as Supreme Commander of the NATO ground forces in Central Europe from 1957 to 1963, as the first German NATO commander during the Cold War, and with headquarters at the Palace of Fontainebleau in Paris. He was also a military historian.
In 1960, Speidel took legal action against an East German film studio which portrayed him as having been privy to the assassinations of King Alexander I of Yugoslavia and French Foreign Minister Louis Barthou in 1934, as well as having betrayed Field Marshal Erwin Rommel to the Nazis after the 20 July Plot in 1944.
