Chinese immigrant, we remember the contribution of a DuPont chemist

WILMINGTON, Del. — A Chinese immigrant and chemist who was instrumental in the 1960s in developing noise reduction technology at the DuPont Experimental Station was honored at a recent ceremony at the DuPont site.

A conference center is named after Theodore “Ted” P. Yin, who worked at the company in the 1960s with his wife, Fay Hoh Yin. DuPont officials recognized their achievements, as well as those of all Asian employees who have contributed to DuPont over the years.

Ted Yin was a physical chemist at DuPont in the elastomers department from 1960 to 1969 and is widely known for his role in the development of noise, vibration and harshness (NVH) reduction. This technology is still used today around the world and can be found in things like dishwashers in homes, wheels in railroad cars, or engines in cars.

Ted died in 1970 at the age of 39, leaving behind his two children, Monona and Duncan, and his wife and mother, Florence.

Fay was a DuPont biochemist who conducted rhinovirus research from 1966 until her retirement in 1991. She survived her husband of 50 years and died in 2020.

Few knew about their moving story, which began in war-torn China, before it was featured in a series last year on Delaware Online/The News Journal.

Monona Yin published a book about her family’s experience in 2017, titled “Riding with the Wind: Three Generations of My Family in China”, and worked with Delaware Online/The News Journal to create a four-part series on the life of his parents. , their connection to DuPont and their lives as Chinese Americans.

Mobility & Materials President Randy Stone was inspired by their history and contributions to DuPont and wanted to do something special to honor the Yin family.

The Theodore P. Yin Conference Center was officially unveiled recently, with Monona, Duncan, and Stone officially cutting the ribbon for the building.

The conference room door features a large black and white image of Ted covering much of the glass. Upon entering, the red and gray walls contain a wall plaque with a photo of the Yin family, several photos of Ted, and a quote from him on DuPont.

Various photos of Ted’s work, along with notes and diagrams of his NVH reduction research, adorn a transparent plaque on a wall adjacent to the door.

As DuPont employees and visitors walked through the room, a monitor hung on the wall displayed photos and information about Theodore and his family’s legacy.

While being honored with plaques for their parents’ accomplishments, Monona and Duncan expressed their gratitude for their parents’ recognition and the dedication of a conference center in their father’s honor.

As he stood in the conference center, Duncan began to cry at the sight of his father’s work lining the walls of the room.

The whole event, and what it means to see her parents’ legacy recognized in this way, was very “emotional,” Monona said.
