Published in conjunction with the Documenta 13 exhibition in Kassel, Germany, the Documenta notebook series "100 Notes,100 Thoughts" ranges from archival ephemera to conversations and commissioned essays. These notebooks express director Carolyn Christov-Bakargiev's curatorial vision for Documenta 13.
Rudolf Arnheim (1904–2007) was a German-born author, art and film theorist, and perceptual psychologist. He learned Gestalt psychology from studying under Max Wertheimer and Wolfgang Köhler at the University of Berlin and applied it to art. His magnum opus was his book Art and Visual Perception: A Psychology of the Creative Eye (1954). Other major books by Arnheim have included Visual Thinking (1969), and The Power of the Center: A Study of Composition in the Visual Arts (1982). Art and Visual Perception was revised, enlarged and published as a new version in 1974, and it has been translated into fourteen languages. He lived in Germany, Italy, England, and America. Most notably, Arnheim taught at Sarah Lawrence College, Harvard University, and the University of Michigan. He has greatly influenced art history and psychology in America.
