Isotype (International System of TYpographic Picture Education) is a method of showing social, technological, biological and historical connections in pictorial form. It consisted of a set of standardized and abstracted pictorial symbols to represent social-scientific data with specific guidelines on how to combine the identical figures using serial repetition. It was first known as the Vienna Method of Pictorial Statistics (Wiener Methode der Bildstatistik), due to its having been developed at the Gesellschafts- und Wirtschaftsmuseum in Wien (Social and economic museum of Vienna) between 1925 and 1934. The founding director of this museum, Otto Neurath, was the initiator and chief theorist of the Vienna Method. The term Isotype was applied to the method around 1935, after its key practitioners were forced to leave Vienna by the rise of Austrian fascism.
The Gesellschafts- und Wirtschaftsmuseum was principally financed by the social democratic municipality of Vienna, which was effectively a separate state (known as Red Vienna) within the new republic of Austria. An essential task of the museum was to inform the Viennese about their city. Neurath stated that the museum was not a treasure chest of rare objects, but a teaching museum. The aim was to “represent social facts pictorially” and to bring “dead statistics” to life by making them visually attractive and memorable. One of the museum’s catch-phrases was: “To remember simplified pictures is better than to forget accurate figures”. The principal instruments of the Vienna Method were pictorial charts, which could be produced in multiple copies and serve both permanent and travelling exhibitions. The museum also innovated with interactive models and other attention-grabbing devices, and there were even some early experiments with animated films.
From its beginning the Vienna Method/Isotype was the work of a team. Neurath built up a kind of prototype for an interdisciplinary graphic design agency. In 1926 he encountered woodcut prints by the German artist Gerd Arntz and invited him to collaborate with the museum. There was a further meeting in 1928 when Neurath attended the Pressa international exhibition. Arntz moved to Vienna in 1929 and took up a full-time position there. His simplified graphic style benefited the design of repeatable pictograms that were integral to Isotype. The influence of these pictograms on today’s information graphics is immediately apparent, although perhaps not yet fully recognized.
