We would like to draw your attention to the exhibition "Max wird Beckmann" at the Herzog Anton Ulrich Museum. The Climatology & Environmental Meteorology Department was involved in the meteorological classification of an early work (Landscape with Lake) by Max Beckmann. We would like to express our sincere thanks to the curator of the exhibition Prof. Thomas Döhring for this exciting collaboration. The picture shows the title page of the Beckmann exhibition catalogue.
