The American chemist Roy Plunkett synthesized in 1938 polytetrafluoroethylene, also known as Teflon, a material with an incredibly low coefficient of friction to which nothing sticks.
French engineer Marc Gregor of the National Aeronautics and Space Laboratory loved to fish. His favorite folding spinning rod began to jam due to dirt and salt getting into the joints. The scientist took a piece of Teflon from work, which they were looking for for use in space, and wrapped it around the joint of a fishing rod. The rotating rod started working immediately.
His wife Colette was fed up with food constantly sticking to her aluminum cookware and asked, "Can we coat the pan with this coating? This is how Tefal (Teflon and aluminum) was born. and non-stick cookware.
Gregoire received a patent for it; Roy Plunkett made no objections. It was in 1954.
