Rupprecht Geiger, son of German painter Willi Geiger, started his career as an architect after graduating with a degree in the field in 1935. Geiger painted his first abstract works in 1948 based on impressions of light and colour. The artist was among the main representatives of German Colour Field painter whose work employed hard-edge geometric abstractions and a riotous palette of pinks, reds, and yellows. Painted in vibrant fluorescent hues, Geiger's oeuvre feature repeated forms and compositions across his many canvases, culminating in an ambitious body of work that seemed perhaps more aligned with the color studies of Josef Albers than his peers Willi Baumeister, Fritz Winter, and Bernard Schultze in the German movement ZEN 49, which he co-founded.
