Günter Fruhtrunk is today principally recognised as a geometric abstract artist. His striking work is both classical and contemporary, and throughout his career principally created works that were abstract and non-figurative. Fruhtrunk started painting watercolours while serving in World War II as a way of dealing with the realities of warfare. He studied in Paris in the studios of Ferdinand Léger and Jean Arp. Fruhtrunk advocated to free Constructivism from its previously tight constraints, supporting a more colourful and loose expression. This is evidenced in the bold and energetic works that typify much of his oeuvre, which has also led his work to be closely associated with Op art. Throughout his career, GünterFruhtunk participated in documenta and the Venice Biennale, and served as a professor at the Academy of Fine Arts in Munich. He is one of the most outstanding representatives of geometric abstract painting of the German post-war generation, and has been celebrated in numerous exhibitions since his death.
