Karel Appel is considered to be one of the most influential postwar Dutch painters. He is mostly known as a renowned member of the Cobra-movement and counted prominent artists such as Corneille and Constant, whom he had been close with since their joint time at the academy, among his peers. Appel’s international breakthrough came in 1957, after Cobra.
He settled in New York and his work progressed slowly toward the abstract arts, although Karel Appel never acknowledged in doing so. Music was an important source of inspiration for him. Karel Appels oeuvre was in a league of its own, albeit heavily leaning on the expressionist arts.
