Georgs Seurat - The Courbevoie Bridge - oil on canvas 46.4 x 53.3 cm - London Courtauld Institute Galleries
Passionate about scientific research on the chromatic dispersion of natural light and on the notions of simultaneous contrast, Georges Seurat initiated the neo-impressionist group with Signac in developing a theory on divisionism, divisions of tones by juxtaposition of "pellets" of color.
