Stephanie Kwolek grew up during the Great Depression and, as any typical little girl, loved to make dresses for her dolls.  When she was in high school, her passion turned to chemistry.  She felt there was a relationship between the two in comparing the meticulousness of both.  Stephanie later went to an all-women’s college and majored in chemistry.  She thought perhaps she could later go into medicine.  However, with a college degree in hand, she landed a job with DuPont, a chemical engineering pioneer at the time, and stayed with them for over 40 years.  During that time, she was challenged with making a thread that was stronger than steel.  Not such an easy task.  After almost 20 years, she discovered a thread made from polymers that when woven together was strong enough to stop a bullet–kevlar was born.  Needless to say, kevlar has made a huge impact on the world, saving many lives of the military and law enforcement.  It is also used in spacecraft, radial tires, roads, brake pads, plus a multitude of other items.  At the end of the book is a section titled, ‘You Be the Inventor.’  It gives examples of kids who have had an idea, patented it, and built a company from it, all at a very young age.  This book is encouraging for kids to follow their dreams.
