Stephanie L. Kwolek is now retired and working part time as a consultant at E.I. DuPont de Nemours & Co., Inc. In 1965, she developed the technology that became the foundation of the Kevlar fiber while working in the Textile Fibers Pioneering Research Laboratory at DuPont's Experimental Station. Kevlar is five times stronger than steel yet 43% lower in density than fiberglass. It is resistant to wear, corrosion, fatigue and flame and is nonconductive. Kevlar in bulletproof vests has saved the lives of thousands of police officers. It has replaced asbestos in friction products such as brakes and is used in fire blocking protective clothing, ropes and cables for use on offshore oil drilling platforms and in aircraft and space vehicle construction.

Ms. Kwolek's name appears on 16 patents; she is sole patent holder on seven. She has authored or co-authored 28 scientific publications and presented her work at national and international conferences.
