Erwin Rommel (15 November 1891 - 14 October 1944), in full Erwin Johannes Eugen Rommel, also known as the Desert Fox, was a famous German general during WWII, especially famous for his spectacular victories in in North Africa.
The Allies considered him so great a threat that two failed assassination attempts were made.
The possible role that Rommel played in the German resistance and the 20 July plot is unclear. Regardless, he was implicated by participants, and took his own life when given the choice.
After the war, possibly related to the attempts to make every aspect of National Socialist Germany negative, Rommel's reputation has been attacked in various ways, with attacks made on his relationship to National Socialism, his military abilities, and his chivalry and his character in general.
Leftist Wikipedia has an entire article dedicated to attacking the supposed "Rommel myth".
