Where did Max Ernst go to school for art?

Max Ernst did not attend a traditional art school. He studied philosophy at the University of Bonn and then briefly studied at the University of Cologne before dropping out to pursue art. He was largely self-taught, but he did have some important influences:

* He attended a private art academy in Brussels: This was a brief period of formal art education, but it was not a traditional art school in the sense of an established institution.

* He was heavily influenced by Dadaism: Ernst was a key figure in the Dada movement, and his early works were heavily influenced by the group's anti-art sensibilities and experimental techniques.

* He learned from his peers and collaborations: Ernst collaborated with other artists, particularly in the Surrealist movement, where he learned and developed his unique style.

So, while Ernst didn't have a formal art education in the traditional sense, he gained his artistic knowledge through self-study, his involvement in avant-garde movements, and collaborations with other artists.
