Walter Dahn counts among the protagonists of neo-expressive art, which saw its heyday in Germany in the 1980s. Walter Dahn, who had studied at the Düsseldorf Academy of Art under Joseph Beuys, belonged to the "Mülheimer Freiheit", a group of artists that was often referred to as the "Neue Wilde" [New Wild Ones], which was largely due to their drastic style of painting but also because of their excessive lifestyle. Walter Dahn's figurative paintings, which always sought to express subjective sensation, are prime examples of the style of the "Neuen Wilden", as they captivate the observer with their exuberant coloring and their gestural-expressive strokes of the brush. Tghe passionate line also dominates the sensitive graphic works by Walter Dahn.
Works by Walter Dahn, who was professor at the Brunswick 'Hochschule für Bildende Künste', are sought-after collector's items on the art market and have been in the focus of numerous exhibitions since the 1970s, which is proof of their international artistic rank.
