In the early 16th century, Gottfried “Götz” von Berlichingen, a knight - and rogue - of the Holy Roman Empire, found his hand ripped off by a cannonball during the Siege of Landshut. This did not stop the staunch German, however, who had an iron prosthetic crafted to replace the appendage. PG-13 for language.
Götz, who became a sort of German Robin Hood, was known for his colorful language, as well as his iron fist. Chris Baker of Wired Magaine has the story and photo.
