The Pied Piper of Hamelin, actually city tourism employee Michael Boyer, leads local children dressed as rats through a quiet street on November 19, 2012 in Hameln, Germany. The Pied Piper (in German: Der Rattenfaenger), is one of the many stories featured in the collection of fairy tales collected by the Grimm brothers, and the 200th anniversary of the first publication of the stories will take place this coming December 20th. Boyer, a U.S. citizen who has lived in Hameln for 15 years, and city children regularly perform a reenactment of the Pied Piper tale throughout the summer months. The Grimm brothers collected their stories from oral traditions in the region between Frankfurt and Bremen in the early 19th century, and the works include such global classics as Sleeping Beauty, Little Red Riding Hood, Rapunzel, Cinderella and Hansel and Gretel.
