Jochen Scheithauer (b. 1948, Kassel) works within the reductive, constructive wing of German concrete art across painting, relief, sculpture and large-scale work in public space. Trained first as a stonemason, he studied at the Academy of Fine Arts in Munich and at the Gesamthochschule Kassel — a background that shows in the material, three-dimensional bent of much of his work, from wall objects and reliefs to room installations and architectural commissions. He has long been active in the Munich constructive scene, including the Berufsverband Bildender Künstler and the Galerie der Künstler, and has shown in the leading forums of the field, among them the Forum Konkrete Kunst in Erfurt, Europa Konkret, and the Museum Modern Art in Hünfeld. His work was presented at the Kunstverein and at the Museum für Konkrete Kunst in Ingolstadt — the institution to which this portfolio is dedicated.
