Pierre Cordier invented the chemigram in 1956. The chemigram combines the physics of painting (varnish, wax, oil) and the chemistry of photography (photosensitive emulsion, developer, fixer); without a camera, without an enlarger, and in full light. Cordier’s abstractions entice us to enter imaginary worlds of form, line and colour. Pierre Cordier’s chemigrams have been exhibited internationally, including at the Centre Georges Pompidou, Paris; the Musée d’Art Moderne, Brussels; the Victoria & Albert Museum, London; and the Museum of Modern Art, New York.
