Rupprecht Geiger (German, 1908–2009) was a leading figure of postwar abstraction and Color Field painting, internationally recognized for his radiant monochromes and hard-edged geometric artworks. The son of painter Willi Geiger, he moved between architecture, painting, sculpture, and printmaking before dedicating himself fully to the exploration of color as an autonomous force.
Geiger’s abstract artworks are defined by precise geometric forms and an intense chromatic vocabulary, most notably his iconic reds. For Rupprecht Geiger, red was not merely a formal choice but a symbol of vitality, energy, and presence. Across paintings and limited edition prints, he investigated how color alone could generate spatial depth and emotional resonance, positioning his work at the forefront of non-objective art in postwar Germany.
In 1949, together with Willi Baumeister and Fritz Winter, Geiger co-founded the artist group Zen 49 in Munich, which played a decisive role in reestablishing abstract art in Germany after World War II. By the early 1960s, he concentrated exclusively on painting and printmaking, producing a body of artworks and fine art prints that remain central to European Color Field abstraction.
Rupprecht Geiger participated in multiple editions of documenta (2, 3, 4, and 6) and exhibited at the Museum for Non-Objective Painting, later the Guggenheim Museum. Major retrospectives at institutions such as the Neue Nationalgalerie in Berlin and the Lenbachhaus in Munich confirmed his enduring significance within twentieth-century art.
