Robert Menot, known as Rob d’Ac, was a French illustrator and advertising artist born in 1891 in Acy-en-Multien. Trained as an engineer, he never abandoned his passion for drawing. After the First World War, he settled in Grenoble, where he became an essential local figure, creating posters, advertisements, illustrations, and children’s books. Inventive and demanding, he explored the art of signs, colors, and forms, blending poetry and graphic design in works such as his “zoomorphs” and “animots.” He died in 1963, leaving behind a rich and vibrant body of work, now preserved by his descendants.
