Deutsches FilminstitutFounded in 1949, the Deutsches Filminstitut – DIF is the oldest cinematic institution in Germany and also one of the country's largest. To collect, process and analyse information on film is one of the main purposes of the DIF. A second purpose is the collection of films, their preservation and, if necessary, restoration in order to bring them back to the screen. In 2006, the Deutsches Filmmuseum, Frankfurt/Main, merged with the DIF and is now an institution of the latter. Together the DIF / Deutsches Filmmuseum now provide an exceptional variety of services and comprehensive expertise in film, but also run two cinemas: the award-winning Cinema of the Deutsches Filmmuseum in Frankfurt and the Caligari Filmbühne in Wiesbaden.
