This pioneer of photomontage, a mixture of two related but quite different media, always remained part photographer, part designer. Often this synthesis resulted in a happy marriage, as in his 1955 poster for the International Photography and Cinema Biennial. He met Herbert Matter at the Deberny et Peignot type foundry, where Charles Peignot acted over many years as a catalyst for new graphic art. Pierre founded Arts et Métiers Graphiques, the leading pre-war French design magazine. With friends he also founded the Alliance Photo, experimenting with all kinds of photographic techniques. He was commissioned to do large murals in France and Great Britain and came up with a technique combining colour graphics and montage. It was a great pleasure to see that he ‘re-appeared’ at the 1997 Barcelona AGI congress.
