Together with our students of the International Master of Cartography, we visited the Otto Neurath exhibition “Sprechende Zeichen“ at the Wirtschaftsmuseum in Vienna. The exhibition is dedicated to Otto Neurath, founder of the Society and Economic Museum. Otto Neurath developed new graphics techniques during the First World War. He was a member of the philosophical Wiener Kreis and developed the Viennese method of image statistics to present statistics in an easily understandable, visual form.
