Duane Pearsall is a hero

why, you may ask?

Because  Duane Pearsall saves lives every day, because he invented the humble Smoke detector

Invented in the 1960s, the smoke detector has proven over and over again to be a life-saving gadget, and some people would literally not be alive without it.

According to an article in the magazine Popular Mechanics, Pearsall said the invention happened by accident while trying to develop a static control device intended for photo dark room purposes.

gotta love an invention accident!!!!
