Stephanie Kwolek, (PHOTO IN 1938) an American chemist who in 1965 invented a super-strong fiber called Kevlar that revolutionized body armor and protected innumerable police officers and soldiers from bullets, has died at age 90.

Kwolek, who worked for the DuPont chemical company for four decades starting in 1946, died in Delaware after a short illness. The company confirmed her death.

"We are all saddened at the passing of DuPont scientist Stephanie Kwolek, a creative and determined chemist and a true pioneer for women in science," DuPont Chief Executive Ellen Kullman said in a statement.
