(b Brussels, 19 Oct 1927). Belgian painter, draughtsman, printmaker and film maker. He studied book illustration and typography at the Ecole Nationale Supérieure d’Architecture et des Arts Décoratifs from 1944 to 1946. In 1947 he became a member of the Jeune Peinture Belge group and had his first one-man exhibition in the Galerie Lou Cosyn in Brussels. In 1949 he became a founder-member of the COBRA movement after meeting Christian Dotremont. With a number of artist friends he set up a type of research centre and meeting-place in Brussels, the Ateliers du Marais. Towards the end of 1951 he went to Paris, moving to Japan in 1955 to study the art of calligraphy, also making a film called Calligraphie japonaise (1956). He adopted the Oriental manner of painting, whereby the paper is spread on the floor and the artist leans over the work holding the bottle of ink, allowing a greater freedom of movement. In 1957 he made his first large works on paper in Indian ink and afterwards mounted the paper on canvas.
