Incredible Things That Were Invented by Women

IN 1965, STEPHANIE KWOLEK DEVELOPED A SYNTHETIC FIBER THAT WAS SO STRONG, IT WAS BULLETPROOF.

When Kwolek started working at the DuPont Company in 1964, her team was focused on finding a strong yet lightweight fiber for tires.

One year later, she made an unexpected breakthrough in her research when she created a a new fiber that was five times stronger than steel. DuPont patented the fiber that same year under the name Kevlar, which is now used in everything from bulletproof vests to military helmets to racing sails.

In 1995, Kwolek became the fourth women to be inducted into the National Inventors Hall of Fame.
