Etch a Sketch inventor Cassagnes, 86, dies in Paris

Invented in Paris in the late 1950s, the mechanical drawing toy that would eventually be marketed as “the world’s first laptop” became wildly popular soon after an Ohio company introduced it under a new name: Etch a Sketch.

French electrician Andre Cassagnes stumbled upon the concept for what he called the “Telecran” – or telescreen – while peeling a decal from a switch plate and noticing how his pencil marks had transferred from one surface to another.

After an Ohio Art Co. executive discovered it at the 1959 Nuremberg Toy Fair, he bought the rights for $25,000 and launched it in time to become the best-selling toy of the 1960 holiday season.

Cassagnes, who was also a noted kite designer, died Jan. 16 in a Paris suburb, the Toy Industry Association announced. A cause was not given. He was 86.

Named one of the top 100 toys of the 20th century by the New York-based toy association, Etch a Sketch appears on the list with such other classics as the Duncan yo-yo, the Barbie doll, Silly Putty and Mr. Potato Head.

The drawing device is fondly recalled by baby boomers and their offspring, who were captivated by the ability to doodle on the flat silver screen as if by magic.

Yet the science behind his invention is relatively simple, based on the notion that an electrostatic charge could hold aluminum powder to glass.

Cassagnes developed the toy with that in mind and designed it to look like a television set. Instead of the now-familiar knobs, he used a joystick to erase the aluminum powder from the glass screen, enabling the user to draw.

Since he couldn’t afford to pay for a patent, he borrowed money from an investor who sent his treasurer, Arthur Granjean, to complete the paperwork. But Granjean’s name ended up on the patent, helping to obscure Cassagnes’ role. When the New York-based National Toy Hall of Fame inducted Etch A Sketch in 1998, it wrongly listed Granjean as the toy’s creator.

An official history on Ohio Art’s website gives Cassagnes credit for the invention.

“Etch A Sketch has brought much success to the Ohio Art Company, and we will be eternally grateful to Andre,” company President Larry Killgallon said in a statement released after Cassagnes’ death. “His invention brought joy to many over such a long period of time.”

As of 2010 various models of Etch a Sketch had sold a total of 150 million units, the Toledo Blade reported that year.

Working with Ohio Art’s chief engineer, Cassagnes helped refine the Etch A Sketch before the first one rolled off the production line on July 12, 1960.
