Charlotte "Lotte" Reiniger (2 June 1899 – 19 June 1981) was a German film director and the foremost pioneer of silhouette animation.
Her best known films are The Adventures of Prince Achmed, from 1926—thought to be one of the oldest surviving feature-length animated films—and Papageno (1935).
Reiniger is also noted for having devised the first form of a multiplane camera; she made more than 40 films, all using her invention.
