Snow White (in German Schneewittchen) is a fairy tale known from many countries in Europe, the best known version being the German one collected by the Brothers Grimm. The German version features elements such as the magic mirror and the seven dwarfs, who were first given individual names in the 1912 Broadway play Snow White and the Seven Dwarfs and then given different names in Disney's 1937 film Snow White and the Seven Dwarfs. The story of Snow White and the dwarfs should not be confused with the story of Snow White and Rose Red (in German Schneeweißchen und Rosenrot), another fairy tale that was also collected by the Brothers Grimm.
