Stephanie Kwolek



Stephanie Kwolek was born in New Kensington, Pennsylvania in 1923. She received her bachelor's degree in chemistry from the Carnegie Institute of Technology in 1946. She went to work with DuPont where she worked in the textiles development division. She created a liquid polymer that when spun into fibers was extremely strong and durable. The fiber came to have the name Kevlar and is used for making bullet proof vests, cables, inflatable water craft and building materials. Kwolek patented Kevlar in 1971 and has also twenty-seven other patents to her name.
