Jean Widmer (born 1929) is a graphic designer and art director based in Paris. He studied at the Kunstgewerbeschule in Zurich, under Johannes Itten, and shortly afterwards moved to Paris, as part of a group of Swiss designers which were to fundamentally influence graphic design in France in the second half of the twentieth century. Widmer was art director at Galeries Lafayette and fashion magazine Jardin des Modes, transforming the graphic outputs of both. Later, his posters for the Centre de Création Industrielle created an unmistakable style, which came to full fruition in his image for the Centre Pompidou and other cultural agents in Paris, as well as in important signage work for the French motorways and tourism signposts throughout the country.
