When Karel Appel passed away in 2006 at the age of 80, he was honored with major retrospective exhibitions across Europe. His journey, however, had been long—from his early attempts in a war-torn Amsterdam to his international recognition as one of the postwar era’s most original and expressive painters.

Appel studied at the Rijksakademie in Amsterdam during the German occupation and debuted in 1947 with a solo exhibition in Groningen. His first major commission, a mural in Amsterdam’s city hall, met with harsh criticism and was covered for ten years—an early indication of how provocative his colorful, spontaneous style could be. Following this setback, he left the Netherlands for Paris, where he soon connected with like-minded young avant-garde artists.

In 1948, Appel co-founded the groundbreaking Cobra group with Asger Jorn, Constant, Corneille, Christian Dotremont, and Joseph Noiret. The name derived from the members’ home cities—Copenhagen, Brussels, Amsterdam—and became synonymous with a new, free artistic approach. Cobra united painters and poets in a shared pursuit of spontaneity and creative joy, directly opposing the intellectual and geometric abstraction of the time.

Appel’s paintings are defined by intense energy and strong presence. Color is applied thickly, sometimes straight from the tube, and bold brushstrokes give his subjects—often animals, humans, or imaginary creatures—a simultaneously brutal and playful character. As Appel himself explained: “If I paint like a barbarian, it’s because we live in a barbarous age.” His work reflects both aggression and vitality, often softened by a naïve humor.
