Walter Leblanc is an important representative of the kinetic and optical art movements.
A co-founder of the G58 Hessenhuis, Leblanc was associated with the ZERO group, with whom he participated in international exhibitions. Following his first one-man show at the Palais des Beaux-Arts (Brussels, 1961), Leblanc organised the exhibition ‘Anti-Peinture’ (Hessenhuis, Antwerp, 1962) and became part of the international group ‘Nouvelle Tendance’. In 1964 Leblanc won the prestigious prize Jeune Peinture Belge/Jonge Belgische Schilderkunst. During 1977 until his early death in 1986, Leblanc was teaching at the Instituut voor Architectuur en Stedenbouwkunde (NHIBS) in Antwerp.
In 2018, Tate Modern (UK) bought five works by Walter Leblanc.
