Product Description

Perseverance, ingenuity, and a keen eye were all that chemist Stephanie Kwolek needed to discover a new family of synthetic fibers, one of which was the incredibly strong Kevlar compound. Author Edwin Brit Wyckoff tells the tale of Kwolek's life from her youth during the Great Depression to her groundbreaking discovery at DuPont. The results of her efforts have led to the production of many products that use Kevlar, including body armor that has saved countless lives.
