WHO: Andre Cassagnes in France
WHY: Andre Cassagnes was working on a light switch plate and realized that the image moved when he used a pencil. After playing with it, he developed the Etch-A-Sketch: easy to play with, not so easy to master.
FUN FACT: The inside of an Etch-A-Sketch is filled with aluminum powder that moves when you turn the knobs. The toy was originally made with a glass screen that broke easily.
