The Etch A Sketch is one of the best known toys of the Baby Boom generation. French inventor André Cassagnes stumbled upon the idea in the 1950s and the core technology of the toy remains today. Cassagnes died Jan. 16 at the age of 86.

The origins of Etch A Sketch go back to the late 1950s, when Cassagnes was installing a factory light switch plate covered with a translucent decal.

Along with the Lite-Brite, the Etch A Sketch was one of the first “fancy” toys we got as kids. I never could draw anything other than a few straight lines on it though.
