Paul Signac was a French neo-impressionist painter born in 1863 in Paris who helped develop the pointillist style of art. He was strongly influenced by Georges Seurat and often painted coastal scenes and boats on the water. In his art, he employed techniques like pointillism, impressionism, luminism, and neo-impressionism, creating small dots of color to form images that captured light and movement. Some of his most famous works include Breakfast (1886), Grand Canal (1905), and The Large Pine (1893).
