The man in the foreground is Wilhelm Voigt, also known as the Hauptmann von Köpenick. He was a famous forgery artist and professional imposter. He successfully masqueraded as a Prussian military officer for a number of years. Although he was later caught and imprisoned for his crimes, he is still celebrated by some as a folk hero. I found this statue honoring him outside the Köpenick City Hall. Photo taken in April 2012.
