wall charts history
the idea to upgrade every day school life by using pictures was supported in the late 18th century by Johann Bernhard Basedow. In 1774 he published a four-volumned book "Elementarwerk" which combined pictures, text and information with merely hundred copperplates. Modern printing methods enabled the spread from rich private schools to rural grade schools. From 1820 to 1836 the oldest mentioned series of wall charts were published with the range of six booklets including 63 large sized charts. The rising 20th century was the golden age for publishers printing wall charts. Artists masterly performed pictures which combined the subject-specific standards of a scientist with the standards given by an educator and finally created a magnificat art work.
