The Brothers Grimm (die Brüder Grimm or die Gebrüder Grimm), Jacob and Wilhelm Grimm, were German academics, philologists, cultural researchers, lexicographers and authors who together collected and published folklore during the 19th century. They were among the first and best-known collectors of folk tales, and popularized traditional oral tale types such as "Cinderella" ("Aschenputtel"), "The Frog Prince" ("Der Froschkönig"), "The Goose-Girl" ("Die Gänsemagd"), "Hansel and Gretel" ("Hänsel und Gretel"), "Rapunzel", "Rumpelstiltskin" ("Rumpelstilzchen"), "Sleeping Beauty" ("Dornröschen"), and "Snow White" ("Schneewittchen"). Their classic collection Children's and Household Tales (Kinder- und Hausmärchen), was published in two volumes, in 1812 and in 1815.
