Ernst Hermanns was a German painter and sculptor.
Edward Ralph Kienholz was an American installation artist and assemblage sculptor whose work was highly critical of aspects of modern life. From 1972 onwards, he assembled much of his artwork in close collaboration with his artistic partner and fifth wife, Nancy Reddin Kienholz. Throughout much of their career, the work of the Kienholzes was more appreciated in Europe than in their native United States, though American museums have featured their art more prominently since the 1990s.
