The Brothers Grimm (die Bruder Grimm or die Gebruder Grimm), Jacob (1785-1863) and Wilhelm Grimm (1786-1859), were German academics, linguists, cultural researchers, lexicographers and authors who together specialized in collecting and publishing folklore during the 19th century. They were among the best-known storytellers of folk tales, and popularized stories such as "Cinderella" ("Aschenputtel"), "The Frog Prince" ("Der Froschkonig"), "The Goose-Girl" ("Die Gansemagd"), "Hansel and Gretel" ("Hansel und Gretel"), "Rapunzel", "Rumpelstiltskin" ("Rumpelstilzchen"),"Sleeping Beauty" ("Dornroschen"), and "Snow White" ("Schneewittchen"). Their first collection of folk tales, Children's and Household Tales (Kinder- und Hausmarchen), was published in 1812.
The popularity of the Grimms' best folk tales has endured well. The tales are available in more than 100 languages and have been later adapted by filmmakers including Lotte Reiniger and Walt Disney, with films such as Snow White and the Seven Dwarfs and Sleeping Beauty. In the mid-20th century, the tales were used as propaganda by the Third Reich; later in the 20th century psychologists such as Bruno Bettelheim reaffirmed the value of the work, in spite of the cruelty and violence in original versions of some of the tales, which the Grimms eventually sanitized.
Twentieth century educators debated the value and influence of teaching stories that include brutality and violence, causing some of the more gruesome details to be sanitized. Degh writes that some educators believe that children should be shielded from cruelty of any form; that stories with a happy ending are fine to teach, whereas those that are darker, particularly the legends, might pose more harm. On the other hand, some educators and psychologists believe that children easily discern the difference between what is a story and what is not and that the tales continue to have value for children. The publication of Bruno Bettelheim's 1976 The Uses of Enchantment brought a new wave of interest in the stories as children's literature, with an emphasis on the "therapeutic value for children". More popular stories such as "Hansel and Gretel" and "Little Red Riding Hood" have become staples of modern childhood, presented in coloring books, puppet shows, and cartoons. Other stories, however, have been considered too gruesome and have not made a popular transition.
Regardless of the debate, the Grimms' stories have continued to be resilient and popular around the world, although a recent study in England appears to suggest that parents consider the stories to be overly violent and inappropriate for young children, writes Libby Copeland for Slate. Nevertheless, children remain enamored with grim stories as the recent success of The Grimm Series by Adam Gidwitz and The Sisters Grimm by Michael Buckley illustrates.
