W. A. Ehren Tool is a ceramist whose work seeks to raise awareness about war. He attended University of California, Berkeley. A third-generation soldier who served as a Marine in Desert Shield and Desert Storm in 1991, Tool began studying drawing when he left the Corps in 1994. His work centers on the production of clay cups, which are decorated with press molds of military medals or bombs and images of war and violence. He often assembles them, broken or intact, into installations or uses them in videos, and then gives them away (thousands to date) as a way to provoke conversations about war.
