Who invented Etch A Sketch and what's the science behind it?
Etch a Sketch was the brainchild of inventor André Cassagnes, who grew up in a family of bakers just outside of Paris between the world wars, but became one of France’s most famous kite designers and toymakers. “He was allergic to flour,” says Bensch. “So he went off into the world of electrical material.”
While working at a wallpaper factory as an electrical technician in the mid 1950s, Cassagnes spotted a light switch plate covered in a plastic decal. After marking the decal with a pencil, then peeling the decal off, he noticed his marks still visible on the other side. He immediately saw the possibilities and began to tinker with other materials at the company.
“This included aluminum powder, which could become static charged so that it adhered to a piece of glass or plastic,” explains Bensch. In the Etch A Sketch, the two knobs are “attached to a monofilament wire,” says Sobey, “which scratches the screen and pulls the aluminum powder so it leaves a line where the cursor was.” Shake the screen, and the powder disperses.
How did Etch a Sketch take off?
When Cassagnes debuted his brainchild, which he named L'Ecran Magique (the Magic Screen), at the 1959 Nuremberg Toy Fair in West Germany, companies didn’t immediately recognize its potential. “One of the problems was that there was nothing else like it,” says Bensch. “People didn’t see what made it appealing.” Plus, he was seeking a $100,000 advance, a king’s ransom for the time, according to Bill Killgallon, retired president of Ohio Art Company, one of the firms that passed on the deal that year.
When Cassagnes showcased the product the following year at the 1960 New York Toy Fair, Ohio Art reconsidered. Taking a huge gamble, they spent $25,000 ($270,000 in 2025 dollars) to license the Magic Screen idea. “It was more than they had ever paid to license a toy before,” says Bensch. “It was an astronomical sum for them.”
The first toys rolled off the assembly line on July 12, 1960, retailing for $2.99. The Ohio Art Company began advertising them—renamed as Etch a Sketch—right away that summer, to start building holiday demand. The plan worked so well that, according to Bensch, the factory’s production line was churning out the toys right up until midday on Christmas eve.
Since the screen visually echoed that of a television set of the time, the Ohio Art Company used TV’s increasing prominence in the United States to market the new plaything. “It was one of the first toys to get intensive advertising on television so they could demonstrate it to potential customers,” says Bensch. Cassagnes originally used a joystick to control the stylus, but the Ohio Art Company replaced it with knobs so it could resemble a television set even more closely. Aside from that, the essential product has changed very little. In 1969, the company replaced the original plate glass screen with a plastic one after an outcry by child safety advocates.
