Klein, a French painter and performance artist, was a leader of the avant-garde movement called Nouveau Réalisme and greatly influenced the development of Minimalism.

His 1958 exhibition The Void featured an empty, white-painted gallery. He experimented with several unorthodox methods to create his works. What were his “living brushes”? Discuss
