Guillaume Cornelis van Beverloo, born in Liege on July 3, 1922 and died in Auvers-sur-Oise, France on September 5, 2010, was a Belgian painter and printmaker of Dutch parents, better known by his pseudonym Corneille. He began to study art sporadically in Amsterdam in 1940. There he met other painters such as Constant and Karel Appel.
Interested in the work of Pignon, Matisse and Picasso, he began exhibiting in 1946. He visited Hungary soon after and discovered surrealism, also inspired by the work of Klee and Joan Miró. Along with Appel and Constant among others, Corneille was part of the "Experimentale Group" (Dutch Experimental Group) as well as Reflex magazine. With those already mentioned, Corneille later joined the CoBrA movement (1948).
The group dissolved in 1951 and Corneille traveled to Paris, where he acquired African art from his trip in 1949 to North Africa. It also began in 1953 to carry engravings to etching as well as ceramic works the following year. The influence of his African collection is evident in the evolution of his work at the end of the 1950s, when he gradually abandoned his abstract landscape and began to exhibit an imaginative style, with landscapes seen in bird's eye, exotic animals and very stylized forms .
