François Morellet was a conceptual painter, sculptor, and light artist. He is best known for his intricate patterns and played a prominent role in the development of geometric abstract art. He believed in the idea of artists as facilitators, and disagreed with the concept of individual genius. He was a key player in the Concrete art movement and was influenced by the Concrete-Constructivist group and Neo-Plasticism. These groups impacted the way in which Morellet saw the picture field as a infinite concept. Along with fellow artists Julio Le Parc and Francisco Sobrino, Morellet co-founded the Groupe de Recherche d’Art Visuel in 1961. This group, formed in Paris, was made up of eleven opto-kinetic artists, among which Morellet was a leading figure. It was formed to research new modes of artistic expressions. It was around this time that Morellet began working with neon tubes. He would later go on to experiment with a wide variety of materials such as fabric, tape and walls.
