Born in 1882, Auguste Herbin turned towards geometric abstraction in 1917 and advocated on its behalf within the Abstraction-Création group between 1931 and 1936 and then at the Salon des Réalités nouvelles from the summer of 1946. He emerged as a master of a new abstract geometric art after the Second World War. At over 60 years old, he invented a “plastic alphabet” that gave birth to a specific language, creating its signs, vocabulary and syntax. His “bold anticipations” had a decisive influence over many artists, such as Vasarely and Jo Delahaut, who largely banished curves from his artistic research, associating them with the organic world.
