Written by world-renowned physician, author and lifelong citizen of Frankfurt Heinrich Hoffman, Stuwwelpeter, (pronounced Stroo-velpayter) or Slovenly Peter, is his most famous character. He began sketching for children to ease their nerves while visiting his doctor’s office, and eventually wrote Struwwelpeter as a gift for his three-year-old son in 1844. It and many other stories quickly became classics (and cautionary tales) worldwide. The small gallery is a collection of original artwork created by Hoffman, editions and parodies of Struwwelpeter from the 19th and 20th centuries, as well as other paraphernalia to do with his life and work as an author and an psychiatric innovator. The book can be purchased in scores of languages - Mark Twain did one translation. It’s worth a look if you are at the Römerberg wandering around, particularly as admission is free and they have a great gift shop.
