In her review of the exhibition “Das Erklären erklären” (Explaining how to explain) about the history of information design, journalist Laura Weissmüller writes: “Images transport information – often much more clearly than bare numbers or matter-of-fact reports. (…) New inventions and new media made the tremendous spread of information graphics possible and popular. And this new barrage of information had to become comprehensible.” As an example of the variety of information design in earlier times and how to transmit knowledge through images, Weissmüller mentions the poster “Der Mensch als Industriepalast” (Man as Industrial Palace) by Fritz Kahn (1926) which is prominently displayed in the article. In addition, she refers to the collector cards “Bilder vom Menschen” (Images of Man) developed by Fritz Kahn and delivered to the subscribers of the Berliner Morgenpost newspaper in 1931. – The exhibition “Das Erklären erklären.” is on view in the MEWO Kunsthalle Memmingen from July 13th to October 6th, 2013 and was conceived by students of the University of Augsburg. It presents the predecessors of modern info graphics. All items in the exhibition are from the collection of Prof. Michael Stoll.
