It was created by Arthur Granjean. See "http://www.answers.com/topic/arthur-granjean">http://www.answers.com/topic/arthur-granjean
Granjean originally called it "L'Ecran Magique" ("the magic
It was licensed by H.W. Winzeler and released as Etch A Sketch
André Cassagnes, an electrician at Lincrusta Company,
conceived of the idea of a mechanical drawing toy using aluminum
powder in a sealed case. (Lincrusta used aluminum powder as a raw
material in its manufacturing process, so Cassagnes was familiar
with its properties and could readily obtain it). He filed a patent
application on the concept in 1957. He also submitted the
concept to an inventors' competition in 1957, where it was
well-received. This encouraged him to seek a manufacturer who could
produce the toy. He was directed to Paul Chaze, the owner of a
plastic injection molding company named MAI.
Chaze agreed to fund development of the device as well as
helping Cassagnes to officially register his patent. Chaze
instructed his accountant, Arthur Granjean, to prepare, file
and pay for the patent on the "tracing device". The patent
application was submitted 28 May 1959, without Cassagnes' knowledge
and under Granjean's name. MAI produced some prototypes and
then licensed the design to a French company, Joustra, which
produced it under the name "Telecran" (the name that Cassagnes used
for the toy) and paid Cassagnes a royalty. It was an immediate
success in France, where it is still sold under that name.
Through a long series of connections, the toy came to the
attention of H. W. Winzeler, president of Ohio Art Company. In
1960, Chaze traveled to Ohio to sell the North and South American
rights to the invention to Ohio Art. In 1965, Chaze and Winzeler
met with Cassagnes. Cassagnes agreed, reluctantly, to relinquish
all rights to the invention, and all future royalties (except in
France), for the sum of $10,000.
Over the course of the next 18 years, Ohio Art paid over $1
million in royalties to Chaze.
