(b Mendoza, 23 Sept. 1928).
Argentinian painter, sculptor, and experimental artist, regarded as one of the leading exponents of Kinetic art. In 1958 he settled in Paris and in 1959 became a founder member of the Groupe de Recherche d'Art Visuel. Le Parc professes to adopt a rational and objective attitude to his work, repudiating the ideas of artistic creativity or symbolic meaning and working according to scientific principles. He often uses the idea of spectator participation, but tries to eliminate subjective response on the part of the observer, looking for an objective and predictable perceptual response to a planned stimulus. Much of his work consists of devices for disorienting the spectator (distorting glasses and so on), but he has also made some outstanding mobiles, using perspex or metallic elements to scatter or reflect the light.
