Nathaniel Wyeth was an American mechanical engineer and inventor. He joined DuPont in 1936 as a field engineer and by 1963 he was the company's first engineering fellow. When he retired in 1976, he had risen to the company's highest technical position. Wyeth is best known for creating a variant of polyethylene terephthalate (PET) to withstand the pressure of carbonated liquids. Wyeth's invention is used widely today for both carbonated and non-carbonated drinks.
