Carlos Cruz-Diez (Caracas, 1923-2019). Franco-Venezuelan artist, he has lived and worked in Paris since 1960. He is one of the most important protagonists of optical and kinetic art, an artistic current that claims "the awareness of the instability of reality." His research reveals him as one of the color thinkers of the 20th century. The plastic discourse of Carlos Cruz-Diez gravitates around the chromatic phenomenon conceived as an autonomous reality that evolves in space and time, without the help of form or support, in a continuous present. The works of Carlos Cruz-Diez are found in prestigious permanent collections such as those of the: Museum of Modern Art (MoMA), New York; Tate Modern, London; Musée d'Art Moderne of the City of Paris; Center Pompidou, Paris; Museum of Fine Arts, Houston; Wallraf-Richartz Museum, Cologne.
