The painter and graphic artist HAP Grieshaber (actually Helmut Andreas Paul Grieshaber) is regarded as a renovator of expressive-representational woodcuts after World War II.
HAP Grieshaber, who had been trained as a typographer, developed his expressive reduced style as early as in the 1930s. However, he could perform his art only in secrecy during the years of the Nazi dictatorship. But yet, the more powerful did his creative energy unfold after 1945. His monumental expressive woodcuts with their abstract but yet objective language would soon gain great acknowledgement. Mythical and religious subjects occupy a special position in the oeuvre of HAP Grieshaber.
Numerous exhibitions, the most recent "Grieshaber und die Moderne" in the 'Städtische Kunstmuseum Spendhaus' in Reutlingen (2009), deliver proof of HAP Grieshaber's significance for graphic art in the 20th century.
