“I was working with these very long-chain ... extended-chain polymers, where you had a lot of benzene rings in them. ... Transforming a polymer solution from a liquid to a fiber requires a process called spinning. ... We spun it and it spun beautifully. It [Kevlar] was very strong and very stiff-unlike anything we had made before. I knew that I had made a discovery. I didn't shout "Eureka!" but I was very excited, as was the whole laboratory excited, and management was excited, because we were looking for something new. Something different. And this was it.”
