In the beginning was the pictogram – to be followed by the word
Germany’s Duden dictionary defines a pictogram as being a 'stylised representation of a thing to convey a specific piece of information or be of directional assistance'. Pictograms were the precursors of writing historically speaking. Back in prehistory, Stone Age dwellers used pictorial symbols to record their experiences for posterity on cave walls. Cuneiform script and hieroglyphs likewise drew on images and symbols.
In the 1920s, the social philosopher and economist Otto Neurath developed an early system of visualisation made up of internationally intelligible pictograms which he called the 'International System of Typographic Picture Education' or, in abbreviated form, 'Isotype'. However, the aim with Isotype was not to substitute verbal and written language but, rather, to support the learning process in children as part of an image-based approach to teaching. The use of pictograms was pioneered at the 1964, 1968 and 1972 Olympic Games in the form of the first pictographic wayfinding systems for the public domain.
