Nathaniel Wyeth

Nathaniel C. Wyeth (October 24, 1911 — July 6, 1990) was an American mechanical engineer and inventor. He is best known for creating a polyethylene terephthalate beverage container that could withstand the pressure of carbonated liquids. Made of recyclable PET plastic, lighter than glass and virtually unbreakable, Wyeth's invention is used widely today for both carbonated and non-carbonated drinks.

Born in Pennsylvania near Chadds Ford, he displayed an engineering talent throughout his youth. Wyeth held bachelor's and master's in mechanical engineering from the University of Pennsylvania. He married Caroline Pyle. They had six sons and a daughter but lost one son in a railway accident and the daughter who died very young. Caroline passed away in 1973. Wyeth married Jean Grady in 1984.

Wyeth joined DuPont in 1936 as a field engineer. By 1963 he was the company's first engineering fellow and when he retired in 1976, was DuPont's first senior engineering fellow, the company's highest technical position.

In 1967, he pondered whether soda could be stored in plastic bottles. After experimenting with a plastic detergent bottle that proved incapable of withstanding the forces of pressurized liquids, he realized that a much stronger material would be required. He initially experimented with polypropylene, but ultimately settled on polyethylene terephthalate as the material and received the patent in 1973.

Wyeth received the 1981 Society of Plastics Engineers international award for outstanding achievement, and was inducted into the Society of the Plastics Industry Hall of Fame in 1986. He was a fellow of the American Society of Mechanical Engineers.

Wyeth's other innovations included improvements to manufacturing process, plastics, textiles, electronics and mechanical devices. He is also known as the brother of painters Andrew Wyeth and Henriette Wyeth Hurd, the father of musician Howard Wyeth, and as the son of artist and illustrator N. C. Wyeth.[1]
