Belgian sculptor and painter who, after having studied at the Académie des Beaux-Arts in Mons, joined the Surrealist group Rupture. His early paintings were strongly influenced by Magritte and Yves Tanguy. In 1947, he joined the Jeune Peinture Belge group in Brussels and, in 1949, he was co-founder of the Cobra group, where he remained until 1951. On discovering the work of Alexander Calder, he decided to join the Abstract Art group in 1952. He developed an interest in changes of time and space which led, in 1953, to his first kinetic objects, Plans Mobiles. In 1963, Bury created his first sculptures in polished wood. In 1972, with the sponsorship of the Renault company, he created a group of 50 moving columns 3 metres high and, in 1976, he began work on hydraulic sculptures which were moved by the weight of water. These were followed by many works integrated in architecture, such as the fountains installed in the courtyard of the Palais Royal in Paris, in Brussels and the Guggenheim Museum in New York.
