Berthold Bartosch (29 December 1893 – 13 November 1968) was a film-maker, born in Polaun, in the Bohemia region of Austria-Hungary (now part of the Czech Republic).
He moved to Berlin in 1920 and collaborated with Lotte Reiniger on her paper silhouette animations: Bartosch created what some consider the first multiplane camera in order to achieve some of the effects for these films.
[1] In 1919, Bartosch opened a branch of Hanslick's production company in Berlin, where he met other artists including Berthold Brecht and Jean Renoir.
Special effects like halos, smoke and fog were made with lather spread on glass plates and lit from behind.
L'idee, when released in 1933, featured a score by composer Arthur Honegger, including an ondes Martenot, which is believed to be the very first use of an electronic musical instrument in film history.
