From 1920 until 1970 artist and graphic designer Gerd Arntz (1900 - 1988) portrayed the world in wood and linoleum cuts. As a communistically inspired liberal artist he created political prints during the nineteen twenties, using them to convey his engaging vision of social wrongs and upcoming fascism in Germany. He did this in such a simple, direct style that anyone - whatever their education and nationality - was able to understand his images. This prompted Viennese social scientist Otto Neurath to ask him to design the symbols for the International System of Typographic Picture Education (ISOTYPE). Artz made more than 4000 coherent, powerful and legible figures. We still see their traces around us on a daily basis: in pictographs featured on objects ranging from traffic signs to gameboys.This book displays many Isotypes and explains the system and the Isotype in context, including a selection of pictographs. An interview with Peter Arntz about his father is illustrated with photos from the private archives that characterize the era (friends of Arntz, Arntz himself, street scenes, etc) with political prints by Gerd Arntz and other rare visual material that has never previously been published (pack of cards, sketches for isotypes, and so forth). The book includes several pages in which designers, artists and art historians express the importance of Arntz's work.
