Jacob and Wilhelm Grimm popularized some of today's most enduring fairy tales. "The Frog Prince; or, Iron Henry" was the first tale to be published in Grimms' Fairy Tales (Kinder- und Hausmärchen) (1812). It tells the story of a princess who befriends a frog who, unbeknownst to her, is a prince under a sorcerer's spell. We are honoured to reproduce this manuscript from the Bodmer Foundation as the first release in our Fairy Tale Collection.
