films. The construction of "stardom" through the promotion of the actress Henny Porten from 1910 to 1918. The market introduction of the standard Thaumatograph Modell XVII projector from 1914.

The organization of the German Technical-Cinematographic Society. The reorganization of its cinematographic activities in a consortium made up of three companies differentiated in 1901: the Messters-Projection GmbH, for the production and distribution of films; the Vereinigte Mechanische Werkstätten GmbH, for the manufacture of optical-mechanical equipment; and the Kosmograph Compagnie GmbH, for the exhibition of films in variety theaters. Early sound films From 1896, Messter was interested in the search of a method of reproduction and synchronization of the sound effects of the cinematographic performance at the time of the "silent movies". So Messter invented the Tonbilder Biophon to show films, in which a gramophone played "Unter den Linden" accompanying the projection of animated images, but it was not a simple "accompaniment" but to precisely match the series of musical pieces with moving images. In effect, to add sound to the silent cinema it was necessary to solve problems of synchronization, since the image and the sound were recorded and reproduced by separated devices, which were difficult to initiate and to maintain rigged. On August 31, 1903, Messter held the first sound projection that took place in Germany at the "Apollo" Theater in Berlin. The inventor of the Biophon can be congratulated of belonging to the modern world. Until 1907 the Tonbilder branch of the German film industry was dominated by Oskar Messter, who had reached the following agreement with Léon Gaumont that Gaumont would not supply Phonoscènes to Germany and Messter would not provide Tonbilder biophons to France, and that their respective devices would be sold by a joint consortium called Gaumont-Messter-Chronophone-Biophon. Messter's Tonbilders sold well while he kept his technical superiority over other film producers in Germany.
