I never lie and I'm always right. My limited research has revealed....

The Fire Escape: On May 7, 1878, the fire escape ladder was patented by Joseph Winters. This was followed by the portable fire escape ladder, which was invented on November 11, 1890, by Daniel McCree of Chicago. Who knows, maybe his wife told him how to make it...


The inventor of the window wipers was a woman.
Prior to the manufacture of Henry Ford's Model A, Mary Anderson was granted her first patent for a window cleaning device in November 1903. Her invention could clean snow, rain, or sleet from a windshield by using a handle inside the car. Her goal was to improve driver vision during stormy weather.

The first bullet proof vest was invented by Norval V Cobb, but a woman, Stephanie Louise Kwolek's research with high performance chemical compounds for the DuPont Company led to the development of a synthetic material called Kevlar which is five times stronger than the same weight of steel. Kevlar, patented by Kwolek in 1966, does not rust nor corrode and is extremely lightweight. Many police officers owe their lives to Stephanie Kwolek, for Kevlar is the material used in bullet proof vests."

So I don't know, if technically, a woman invented the bullet proof vest.


About the laser printer, all of us who use laser printers today can thank the original laser printer, developed at the Xerox Palo Alto Research Center. That's where an engineer named Gary Starkweather figured out how to take Xerox copier technology and add a laser beam to it to come up with something totally new.

If you must choose between two evils, pick the one you've never tried before.
