Struwwelpeter (shock-headed" Peter)

Finally managed to get a very old copy of Struwwelpeter (shock-headed" Peter)
this is a very dark and strange collection of childrens stories. Written in 1845 by Heinrich Hoffman. Hoffmann wrote the book in reaction to what he perceived as a lack of good books at the time for children.
 

In six short, illustrated stories, Hoffman, a physician from Frankfurt, told grisly moral tales: of a boy who wasted away after refusing his soup, another who lay writhing in pain after a mistreated dog exacted revenge, and yet another who had his thumb cut off after he sucked on it one too many times. Struwwelpeter’s sin was that he never cut his nails, bathed, or combed his hair; his punishment was distinct and cruel—he was unloved. Hoffman spared none of his fictional children. When they misbehaved, they were punished. Cruel Frederick, for instance, was nasty to all creatures, pulling wings off of flies, killing birds, and throwing kittens down the stairs. But when Frederick beat his dog without mercy, the dog turned on him. Frederick ends up in the bed, wounded and sick, and the dog is never punished. He gets to eat the boy’s dinner (at the table, no less). Text from Atlas Obscura The 19th Century Book of Horrors

In 1955 Writer/director Fritz Genschow adapted Hoffmann's book to the big screen. Previously he had made film adaptions of Hansel and Gretel and would go on to adapt Cinderella, Sleeping Beauty
and other family films. A stage production of Shockheaded Peter, by Philip Carr and Nigel Playfair, with music by Walter Rubens, premiered at the Garrick Theatre in London on 26 December 1900.
