T-fal is a brand name used by the French company Tefal, which marketed and possibly invented the first nonstick pots and pans. The name Tefal is derived from the combination of the words Teflon and aluminum.
Teflon's chemical name is polytetrafluoroethylene, although Teflon is often preferred due to its brevity. According to Tefal, engineer Marc Grégoire was using Teflon on his fishing lures, which led his wife to inquire about using it on pots and pans to prevent sticking. In 1954, Tefal released nonstick pots and pans, and the company still sells kitchen equipment based on this combination. The T-fal brand was first introduced in the United States in the 1960s.
