Stephanie Kwolek was born in Pennsylvania, her parents having immigrated to the US from Poland. She began working for DuPont as a chemist, putting off medical school. She retired in 1986 having won numerous awards and obtaining a number of patents - Kevlar, among others.

One of the first law enforcement officers I met was an Arapahoe County sheriff's deputy who was shot by a suspect wielding a shotgun. The buckshot pellet - roughly the size of a 32 caliber bullet, was stopped by his vest (not before putting a hole in his tie). One of the members of my department, when he was working for another agency, was saved by his vest during a gun battle.
Ms. Kwolek apparently did not spend a lot of her time figuring out ways to use her invention - she was a research chemist, after all. That's okay. Others have taken it from there. In my locker, smelling vaguely of Fabreze, is a piece of equipment I wear every duty day. I hope it never lives up to its intended use but, if it does, I will also be able to live up to mine. I will have the daughter of Polish immigrants to thank.
Farewell, ma'am. Thank you.
