Dutch artist Karel Appel (b. 1921- d. 2006) was born in Amsterdam, Netherlands, and became known for his remarkably colorful and turbulent compositions. He strove to imbue his work with childlike energy, choosing colors and forms instinctually rather than constraining himself with traditional aesthetic principles. Due to his innovative and highly creative approach, he is often credited as a founding member of the avant-garde movement. Appel began painting at the age of fourteen and went on to study at Amsterdam’s Rijksakademie van Beeldende Kunsten between the years 1940 and 1943. In 1946 he hosted his first solo show at the Beerenhuis in Groningen, Netherlands. He became affiliated with groups such as the Jonge Schilders (Young Painters) at the Stedelijk Museum and the Nederlandse Experimentele Groep (Dutch Experimental Group). In 1948 he became a founding member of a group of artists known as CoBrA (a name formed from the initials of the capital cities of the members’ home countries – Copenhagen, Brussels, and Amsterdam) alongside other artists such as Constant Nieuwenhuys and Guillaume Cornelis Beverloo. The group played a formative role in driving the avant-garde movement and their work was collectively characterized by a bold and expressive style that drew on folk art and children’s drawings. In 1950, Appel moved to Paris where he continued to exhibit his work and was eventually awarded the UNESCO prize. During the decades that followed he exhibited his work in Mexico, the United States, Canada, the Netherlands, and France while continuing to acquire notoriety across the globe. In the 80s he developed a partnership with the American poet Allen Ginsberg and continued this work over the course of the next decade. He passed away on May 3, 2006, in Zurich.
