Guillaume Cornelis van Beverloo (born 1922), better known under his pseudonym Corneille, is a Dutch artist.
Corneille, Cornelis van Beverloo was born in 1922 in Liege in Belgium. Corneille studied art at the Academy of Art in Amsterdam, in the Netherlands. He was one of the founders of the Experimentele Groep Holland in 1948 and in 1949 he was also one of the founders of the COBRA group. He was active within the group from the beginning, not only painting but also publishing poetry in the Cobra magazine. The poetic Corneille was strongly influenced by Miro and Klee. After the group dissolved in 1951 he moved to Paris and began collecting African art. These primitive artifacts became evident in his works, which began to take on a more imaginative style, like landscapes seen from a bird’s eye view, exotic birds and stylised forms. Corneille died on september 5, 2010 at the age of 88 in France, where he lived and worked.
