A group exhibition of kinetic art titled Le Mouvement in 1955 introduced works by younger artists such as Jess Rafael Soto, Jean Tinguely, Victor Vasarely, Yaacov Agam, Pol Bury, Robert Jacobsen and Richard Mortensen as well as showing pieces by their role models Marcel Duchamp and Alexander Calder. The show thus laid the foundation for the popularity of kinetics as a form of artistic expression. This authoritative collection re-stages the legendary 1955 exhibition, outlining the pioneers and practitioners of the movement.
