![]() ![]() Cassagnes’ name for it had been the “Telecran”, which is still what the Etch a Sketch is called in France today. While Granjean had no part whatsoever in inventing the Etch a Sketch, he did give the device the name “L’Ecran Magique” (The Magic Glass).This was a fraction of the annual royalties paid to Chaze which added to about $60,000 a year in the United States alone. In 1965, despite the Etch a Sketch’s extreme popularity, Chaze somehow convinced Cassagnes to relinquish all rights to the Etch a Sketch, except for sales in France, for a mere $10,000.Granjean then assigned the French patent rights to Paul Chaze so Chaze could market it. Chaze’s accountant Arthur Granjean filed the patent, which is why it is under his name and why most places state that he was the inventor. He eventually acquired an investor by the name of Paul Chaze to be able to do this. Unfortunately for him, he did not have the money to ultimately register his patent ($200 U.S.). That same year, he won a top prize at the Paris Concurs International D’Inventions for this concept and drawing. Cassagnes originally applied for the patent application for the drawing toy concept in 1957. ![]() If you know much about the history of the Etch a Sketch, you might be saying “But wait, Arthur Granjean was actually the one who invented the Etch a Sketch! It says so on the patent.” It turns out, Arthur Granjean did not invent the Etch a Sketch, as the vast majority of informational outlets state.Together with Jerry Burger of the Ohio Art Company, the two eventually perfected the final design to look like a flat TV set and use a knob system for controlling the drawing. Cassagnes began experimenting with trying to create a children’s drawing toy in the early 1950s and eventually came up with a decent enough concept to market. Cassagnes also later became one of the world’s most famous kite inventors. The Etch a Sketch was invented in the in 1950s in France by an electrician named André Cassagnes (note: not Arthur Granjean, which the vast majority of outlets state was the inventor for reasons stated below).The Surprisingly Long History of Nintendo.The Slinky was Originally Intended to be Used as a Tension Spring in a Battleship Engine Horsepower Meter.The Development of the Video Game “Pong” was a Training Exercise for a New Gaming Developer at Atari and Wasn’t Originally Intended to Be Released.If you liked this article and the Bonus Facts below, you might also enjoy: The lines this creates are black simply because there is no light inside the Etch a Sketch except what comes through the lines you’ve created. The stylus then simply scrapes off the aluminum powder from the glass wherever it’s touching. So by turning an Etch a Sketch upside down and shaking, you effectively coat the glass with a thin layer of aluminum powder, which then adheres to the glass fairly well. This is all connected to the stylus via a very stiff wire.Īmong other things, aluminum powder has an interesting property in that it sticks to quite a lot of things, including glass, via an electrostatic charge. The tiny beads are mixed in with the powder to make sure the powder will continue to flow evenly and not get clumped together, as well as aid in the re-coating process when you shake the Etch a Sketch.Įach knob is connected to either a horizontal or a vertical rail, which in turn is connected to a pulley system. The primary components are just a small sheet of glass a stylus controlled by two knobs very fine aluminum powder and tiny plastic beads. Today I found out how an Etch a Sketch works.Īn Etch a Sketch is a remarkably simple device. ![]()
