[At DuPont,] I was very fortunate that I worked under men who were very much interested in making discoveries and inventions. They were very much interested in what they were doing, and they left me alone. And I was able to experiment on my own, and I found this very stimulating. It appealed to the creative person in me.
Stephanie KwolekAll sorts of things can happen when youโre open to new ideas and playing around with things.
Stephanie KwolekI 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.
