become research director and later executive vice president for development.
Harry concentrated his efforts on polymers, contributing methods for the use of catalysts in their synthesis and graft polymerization, and also plastics, textiles, and insecticides. Later he worked on cyanoacrylate adhesives, now known as “superglues.” Originally, work on these compounds was directed toward their possible use as plastics for impact-resistant jet canopies and as optically perfect gun sites for the military.
Famously, a lab associate inadvertently stuck together the lenses of an expensive refractometer, thus ruining the device. This was the “lightbulb” moment. Harry always said it was “one moment of serendipity and 10 years of hard work.” Afterward, in a moment of television history, Harry and TV host Garry Moore hung from a device joined by one drop of superglue on the show “I’ve Got a Secret.”
Ultimately, Harry was awarded more than 460 U.S. patents and became a champion for innovation and applied research. One of his passionate ideas was to engage the entire company in the research process. This he called “Programmed Innovation.” Under his direction, an example of this process resulted in a method for the gasification of coal. Even after retirement, Harry’s zeal landed him positions as a consultant for new product development at Locktite Corporation and the Reilly and Lilly chemical companies.
Numerous awards during his career included the Southern Chemist Award and the Gold Medal of the Industrial Research Institute, of which he was later elected president. In 2004 he was inducted into the Inventors Hall of Fame in Akron, Ohio. In 2010 he was awarded the National Medal of Technology and Innovation at the White House by President Obama.
Harry’s last philanthropic act was to create a lovely multiuse memorial dome in memory of his wife of over 60 years, Muriel Zumbach Coover, on the grounds of the Allendale Mansion in Kingsport, Tennessee. He also endowed a grant for the development of an outdoor pavilion for the arts at the same site.
