Jacob (1785-1863) and Wilhelm Grimm (1786-1859) were German academics, philologists, and cultural researchers who together collected and published folklore during the 19th century. Their 'Children's and Household Tales' (1812-1857) preserved over 200 German folktales including 'Snow White,' 'Cinderella,' and 'Hansel and Gretel.' Beyond collecting tales, they pioneered the scientific study of language and folklore, with Jacob Grimm's 'German Grammar' establishing Grimm's Law, a foundational principle of historical linguistics.
