This richly illustrated monograph is the first book about the graphic designer, advertising artist, architect, poster and book designer Wilhelm Deffke, who was born in the Rhineland in 1887 and is considered one of the pioneers of modern corporate design. Designated as the 'Father of the Modern Logo' by US critic Steven Heller, Deffke is internationally known among insiders today, but only a fraction of his designs has ever been shown. Now, Wilhelm Deffke's work is being presented to a wider audience for the first time. Fourteen essays place the various aspects of Deffke's work in the context of European design development, and more than 500 illustrations showcase his pioneering achievements in the field of poster and applied graphics, particularly his over 10,000 corporate and product logos, as well as designs for exhibitions and trade shows. The book was designed by Jianping He.
