The International System Of Typographic Picture Education was developed by the Viennese social scientist and philosopher Otto Neurath (1882-1945). Gerd Arntz was the designer tasked with making Isotype’s pictograms and visual signs. Eventually, Arntz designed around 4000 such signs from industry, demographics, politics and economy. The pictograms designed by Arntz were used in combination with stylized maps and diagrams. Neurath and Arntz made extensive collections of visual statistics in this manner, and their system became what we now call infographics.
