Karel Appel was born in Amsterdam on 25 April 1921.
He died in Zurich on 3 May 2006.
Karel Appel studied at the Academy of Fine Arts in Amsterdam
from 1940 to 1943.
His interest was then on Picasso, Paul Klee and Henri Matisse.
The first exhibition of Karel Appel takes place in 1946.
In 1948, Karel Appel was one of the founders with Corneille
and Constant of the experimental group Reflex,
which became the Dutch nucleus of the Cobra group.
Cobra brings together artists from Copenhagen,
Brussels and Amsterdam, hence its name.
Infantile art is one of the sources of inspiration of this group.
In the years 1946-1951, Karel Appel realized many raised
wooden panels and murals on the theme of the child.
He describes themas works "powerful, primitive, stronger
than Negro art and Picasso".
Emblems of revolt and truth, these works make children
appear as derisory actors of a helpless revolt.
In 1949, a wall painted on this theme in the canteen of the
Amsterdam City Hall caused a scandal due to protests from
municipal officials. The work is covered with wallpaper
for ten years. "Appeal made something violent, but of
just violence, popular: Call is of the people, it does not have
the sense of the old surrealist scandal.
