François Morellet, a prolific self-taught painter, sculptor, and installation artist, developed a radical approach to geometric abstraction during a career spanning more than six decades. His object-based paintings, neon and architectural installations, and site-specific works explored the creative potential of kinetic and pre-established systems, challenging the viewer’s understanding of perception and the physical picture plane. An exhibition of the artist’s work will be presented in New York in January 2021.
