Horacio Garcia-Rossi is a visual artist, born in 1929 in Buenos Aires, Argentina and died September 5, 2012 in Paris. From 1950 to 1957, he studied at the National School of Fine Arts in Buenos Aires. During his studies, he met Demarco, Julio Le Parc and Francisco Sobrino.

In 1960, he co-founded the Research Center of Visual Art and GRAV with Julio Le Parc, Morellet, Francisco Sobrino, Joel Stein, Yvaral. Interested in the analysis of visual phenomena, Garcia-Rossi introduced in 1962 the actual movement and light in his research. There are the first experiences geometry on screens. He develops at the same time artpieces that can be manipulated by the viewer (cylinders rotation), and starts a continual research on the problem of instability with light and movement, such as unstable light boxes with colors and patterns handle, and light structures to changing colors. In 1966, the first experiments with the visual identification of writing (Movement), which lead to an ABC move (ambiguous portrait of the members of GRAV), then in 1969, a systematic search for a alphabet ambiguous trying to give each letter the movement its form and meaning have as a letter. From 1972 to 1974, Horacio Garcia Rossi returns to the two-dimensional plastic problems and looking for a simple structure by analytical means. Thorough study of color and its possibilities. From 1974 to 1978, his research is on the problem of language as a subject of the work. From 1978, he works on the problem of the color-light.

He creates artpieces in two dimensions, in which background light and color in an indissoluble unity. In this research, the color appears neither as a decorative element or as a variety of mixed colors, but as a group for creating a new structure of the visualization: color-light. this color-light, radiant, amalgamates in the retina of the viewer, with a rigorous and controlled dosage, all the elements that compose this research.
