Stephanie Louise Kwolek (1923-2014)
As a child Kwolek loved fashion and textiles. Instead of pursuing a career in clothing design, she studied chemistry in college. After graduating, she began working for DuPont. While at DuPont Kwolek discovered liquid crystalline polymers, which resulted in a fiber that was stronger than steel but very lightweight and flexible. DuPont used this to create the product Kevlar. Kevlar is used to make bulletproof vests, radial tires, airplane fuselages and fiber optic cables.
