Christian Landenberger is one of the painters in Germany who dealt with plein-air painting in impressionist manner from early on. From 1883 to 1885, he studied at the Munich Art Academy, but shortly thereafter turned to an unacademic, direct approach to painting, from which new developments emerged, especially in the landscape genre. In 1892, he was a founding member of the Munich Secession, and regularly showed works in the exhibitions until 1916. One motif of Impressionism, which he repeatedly dealt with from 1893, are the bathing boys. Summer painting stays had repeatedly taken him to Lake Constance and Ammersee, where the surroundings offered him the perfect conditions for the implementation of light effects, atmospheric moods and the relaxed unity of man and nature, as well as the observation of the children's natural movements and postures without any artificiality. The surface of the water in particular allows for an iridescent use of color that is detached from the local color and is applied in a very relaxed and spontaneous style. For one of these motifs, "Sommerabend am See" (Summer Evening by the Lake, Neue Pinakothek, Munich) from 1904, he received the gold medal at the 10th International Art Exhibition in the Glass Palace in Munich. The "Badenden Knaben", a motif to which Max Liebermann devoted himself in more than 30 versions from the late 1890s with great success, is one of the central themes of German Impressionism and is therefore of central importance for Landenberger's work.
