The Slovenian Theatre Museum was founded under the aegis of the Slovenian National Theatre in Ljubljana in 1952, to mark the 60th anniversary of the Provincial Theatre in Ljubljana. The first director was Janko Traven, who collected an enormous amount of material from the early periods of Slovenian theatrical history. Prior to 1945, he brought together in the museum materials from theatre archives. Donors of private collections also supported him. Traven published a series of articles on Slovenian theatrical and film history in various newspapers and magazines, mostly in the theatre pamphlets. After the death of Janko Traven, the new director, Dusan Moravec, began sorting out the collected material more systematically, with the assistance of his associates. In 1964 they started issuing documents and articles about Slovenian theatrical and film history in the magazine "Documents of the Slovenian Theatre Museum". It has countinued to be published twice a year. Dusan Moravec and his associates started publishing "The Repertoire of Slovenian Theatres", in order to mark the 100th anniversary of the Drama Society. In 1978, the Theatre Museum merged with the Film Museum in Ljubljana. Hence the institution has since 1979 been called National Theatre and Film Museum. The film department has published numerous independent studies and series of papers from the domain of the history and theory of Slovenian film. The museum acquired its own display rooms, a hall for performances and offices for the first time in 1990. In August 1996 the National Theatre and Film Museum was devided into two independent institutions: Slovenian National Theatre Museum and Slovenian Cinematheque
