Friedrich Wilhelm Voigt (13 February 1849 – 3 January 1922) was a German impostor who, in 1906, masqueraded as a Prussian military officer, rounded up a number of soldiers under his "command", and "confiscated" more than 4,000 marks from a municipal treasury.
Although he served two years in prison, he became a folk hero as The Captain of Köpenick (Der Hauptmann von Köpenick ) and was pardoned by Kaiser Wilhelm II.
