Created in one piece and without cutting the surface, Peter Weber's works position the phenomenon of folding in the field of vision of their viewers. The entire bandwidth of his oeuvre, extending back over 50 years, is now being compiled and acknowledged in a two-volume catalogue raisonné. After his studies in the Department of Design at the University of Applied Sciences in Hamburg, Peter Weber (*1944) continued to focus his entire attention on the creation of concrete art. His early years as a painter were determined by Op-Art and the imaginary space, but he soon became fascinated by the mathematical diversity of the techniques of folding. In addition to felt and paper the artist also uses materials such as linen, cotton, plastic and steel - always uncut and as a whole. The catalogue raisonné assembles in Volume 1 the seven main work groups with explanatory essays. Volume 2 lists chronologically over 1,700 works from all creative periods.
