Venezuelan painter and Kinetic artist, resident in Paris since 1960. In 1960 he settled in Paris, where he became friendly with other Latin American artists, notably his fellow Kineticist Soto, and continued the experiments with arrangements of primary colors he had started during his earlier visits. Using arrangements of thin intersecting bands he found he could create the illusion of a third or fourth colour. This led to a series of works entitled Chromatic Induction, Chromointerference, Additive, and Physichromie. In the last—low reliefs which he started making in 1959—he created shifting geometric images that emerge, intensify, change, and dematerialize as the viewer moves in front of them. He achieved this effect by using narrow strips of painted metal or plastic arranged in parallel lines or at right angles to each other. His work has been featured in many international exhibitions and he has won several awards, including the International Painting Prize at the São Paulo Bienal in 1967. He represented Venezuela at the 1970 Venice Biennale. His later work has included architectural installations, or ‘chromatic environments’ as he calls them, in public buildings.
