As one of the few pioneering female chemists in the 1960s, Stephanie Kwolek invented the flexible, tougher than steel fibers that were used to create life-saving body armor for law enforcement and soldiers.

Kwolek died this week at the age of 90, her co-workers at DuPont, the chemical company where Kwolek worked, confirmed to ABC News.
