It is particularly his watercolors that made Oskar Koller, died in 2004, famous on both a national and international level.
Oskar Koller, who also was a founding member of the "Kunsthauses Nürnberg" [Nuremberg Art House], is regarded one of the most important Franconian artists after World War II. His paintings, graphic art, drawings and watercolors are dedicated to city and architecture views in his early period of creation, later they are dominated by flowers, trees, landscapes and portraits["Menschen und Gesichter"(People And Faces)], at times abstract motives can also be found. However, Oskar Koller achieved particularly virtuous compositions in watercolors in which he swiftly set hinted touches of color, their abstract reduction and decorative coloring make for great aestethic effects.
The Oskar Koller Foundation has been in charge of the artists estate since 2002. Additionally, the artist is honored in the Kunstmuseum Erlangen with a permanent exhibition.
