HAP Grieshaber (1909-1981). From the blog:
A woodcut artist who opposed militarism and war, [Grieshaber] spent years silenced for his pacifism. He lived and worked in England, France, and Greece before the war, but got deported back to Germany because of his pacifism. In Germany, after 1933, he was only able to create art in secret. Grieshaber did manual labor and delivered newspapers to earn a living during WWII, but still continued to work on his woodcuts. It wasn’t until after the war and after Grieshaber was released from an American internment camp, when the country was desolate of artists and in desperate need of art, that anyone was interested in the work he was doing.
Grieshaber's works are powerful meditations on death and culpability.
