Stephanie Kwolek starts this interview by describing her family background. Her father's early death meant that her mother had to work to support Kwolek and her brother, who later became a chemical engineer. At the Carnegie Institute of Technology, Kwolek shifted her interests from medicine to chemistry. Deciding to enter industry, she accepted a position with the Rayon Department of DuPont at Buffalo. There, she started her career in polymer synthesis and worked with Izard, Wittbecker, and Morgan. When the laboratory moved to Wilmington, Kwolek was associated with the low -temperature polymerization program. In the interview, Kwolek then discusses the nylon rope trick, DuPont promotion policy, and liquid crystalline polymers. She concludes with her reflections on colleagues and DuPont consultants.
