The Oskar Reinhart Museum houses around 500 paintings and sculptures from the end of the 18th to the mid-20th century from Germany, Austria and Switzerland as well as around 7000 prints and drawings from the 15th to 20th century. In terms of German art from the 19th century, the Museum is the worldwide leading institution outside of Germany regarding its wealth and quality. The criteria that Julius Meier-Graefe, Hugo von Tschudi and Alfred Lichtwark had set in 1906 at the Centennial Exhibition of German Art in Berlin were decisive for the collection, as Swiss and Austrian artists were also represented in this exhibition. This event was significant, because it triggered a revaluation of German paintings: everything academic and historically emotive was excluded. Instead, the exhibition simply featured Romantic poetry in image form, living Naturalism in Realism and the “picturesque”. At the same time, artists such as Caspar David Friedrich, Georg Friedrich Kersting and Carl Blechen were rescued from oblivion thanks to this exhibition, whilst the exhibition represented the transnational significance of Hans von Marées, Wilhelm Leibl and Hans Thoma for the first time ever. Oskar Reinhart saw the legendary “Centennial Exhibition” and integrated more than twenty works that were exhibited there into his Collection throughout the course of his life. This included renowned paintings by Arnold Böcklin, Wilhelm Leibl and Anselm Feuerbach.
