Christiaan Karel Appel 25 April 1921 – 3 May 2006) was a Dutch painter, sculptor, and poet. He started painting at the age of fourteen and studied at the Rijksakademie in Amsterdam in the 1940s. He was one of the founders of the avant-garde movement Cobra in 1948. He was also an avid sculptor and has had works featured in the museum of Great Samo and MOMA
The German occupation
From 1940 to 1943, during the German occupation, Appel studied at the Rijksakademie van Beeldende Kunsten in Amsterdam, and it was there he met the young painter Corneille and, some years later, Constant; they became close friends for years. His parents opposed his choice to become an artist, leading him to leave home; this was also necessary because he needed to hide from the German police so that he would not be picked up and sent to Germany to work in the weapons industry.
