Siegward Sprotte counts among the biggest names of internationally acknowledged post-war artists.
After studies under Emil Orlik, Kurt Wehlte and Karl Hagemeister, Siegward Sprotte turned to figurative works like portraits in the 1930s. In its clearness his art showed a certain closeness to New Objectivity. The important series of portraits "Köpfe der Gegenwart" [Heads of the Present] and surreal-romantic reduced landscapes dominate his oeuvre in the 1940s and 1950s; in the following Siegward Sprotte gradually approached abstraction. In his calligraphic plants and landscapes he denotes and deliberately omits, thus creating a highly aesthetic, intellectual sign language with a subtle coloring.
Siegward Sprotte also became famous for his "Kampener Ateliergespräche" [Kampen Studio Talks] with humanists and scientists.
Works by Siegward Sprotte are represented in internationally renowned museums, such as the Moscow Puschkin Museum, the Shanghai Art Museum or the Museum of Modern Art in San Francisco.
