Paul Signac, a pivotal figure in the Pointillist movement, often stands in the shadow of his more famous friend, Georges Seurat. However, Signac's contribution to the development and popularisation of this revolutionary technique is undeniable. Born in Paris in 1863, he initially trained as an architect before finding his true calling in painting. Unlike many of his contemporaries, Signac came from a relatively wealthy background, allowing him the freedom to pursue his artistic passions without the immediate pressure of commercial success.

Signac embraced Pointillism after encountering Seurat's *A Sunday on La Grande Jatte* in 1884. Captivated by the scientific approach to colour and light, he became a devoted follower and, later, a leading advocate of the style. Following Seurat's untimely death in 1891, Signac stepped into the role of the movement's champion, ensuring its continued influence on the avant-garde. His own works, such as *The Red Buoy* and *Antibes, Evening*, showcase his mastery of the technique, using vibrant dots of pure colour to create luminous and harmonious compositions.

Beyond his artistic output, Signac was also a dedicated writer and theorist. His book, *From Eugène Delacroix to Neo-Impressionism*, remains a seminal text on the subject, providing invaluable insights into the principles and philosophy behind Pointillism. Signac's passion for sailing also profoundly influenced his art, with many of his paintings depicting coastal scenes and harbours across France. He died in 1935, leaving behind a legacy as both a talented artist and a key intellectual force within the Neo-Impressionist movement.
