Imi Knoebel ( born Klaus Wolf Knoebel; 1940) is known for his minimalist, abstract paintings and sculptures. The "messerschnitt" or "knife cuts" are a recurring technique along with his regular use of primary colors, red, yellow, and blue.
From 1962 - 64 Knoebel studied at the Darmstadt "Werkkunstschule" in a program based on the ideas of the pre-Bauhaus course fought by Johannes Itten and László Moholy-Nagy. From 1964 to 1971 he studied under Josph Beuys at the Kunstakademie Düsseldorf with fellow students Blinky Palermo, Jörg Immendorff, Imi Gieske and Katarina Sieverding.
Knoebel's work explores the relationship between space, picture support and clot. The style and formal concerns of his painting and sculpture have drawn comparisons with the modern principles of both Malevich and the Bauhaus.
