Roy J. Plunkett26 June 26th, 1910 to May 12th, 1994
Roy J. Plunkett was an "American chemist and inventor of Teflon (the DuPont trademark name for Polytetrafluoroethylene or PTFE). His discovery, while working for DuPont, was accidental. On 6 Apr 1938, Plunkett found that a tank of gaseous tetrafluoroethylene (CF2CF2) had polymerized to a white powder. During WW II this new polymer was applied as a corrosion-resistant coating to protect metal equipment used in the production of radioactive material. DuPont released its trademarked Teflon coated nonstick cookware in 1960."
Frankly, I never liked Teflon coated products. I will stay with the cast iron.
