German-born Max Ernst was a provocateur, a shocking and innovative artist who mined his unconscious for dreamlike imagery that mocked social conventions. A soldier in World War I, Ernst emerged deeply traumatized and highly critical of western culture. These charged sentiments directly fed into his vision of the modern world as irrational, an idea that becamethe basis of his artwork. Ernst's artistic vision, along with his humor and verve come through strongly in his Dada and Surrealists works; Ernst was a pioneer of both movements. Spending the majority of his life in France, during WWII Ernst was categorized as an "enemy alien"; the United States government affixed the same label when Ernst arrived as a refugee. In later life, in addition to his prolific outpouring of paintings, sculpture, and works-on-paper, Ernst devoted much of his time to playing and studying chess which he revered as an art form. His work with the unconscious, his social commentary, and broad experimentation in both subject and technique remain influential.
