What does a bulletproof vest, laser printer and a fire escape have in common?

"They were all invented by women. By the way, you forgot to add windshield wipers, since that one is usually included when asking this very old and commonly asked question." http://www.mindlesscrap.com/stumpme/01-03.htm#0103f Above were NOT my words...as I have never heard this question before.

Technically the Laser Printer is credited to Gary Starkweather from Xerox PARC where in 1971 he invented and produced the first Laser Printer... The Laser Printer was built on technology originally developed by Chester Carlson of Xerox (the copier). http://en.wikipedia.org/wiki/Laser_printers Jul 13 06, 9:03 AM

Actually a man invented the first run at the bullet proof vest: http://www.npr.org/templates/story/story.php?storyId=4625858 Jul 31 07, 6:53 AM

Women invented the following, for starters: Bullet Proof vest, fire escape {Anna Connelly built the fire escape stairs in 1887}, windshield wipers [Mary Anderson], dishwasher, home security system [burglar alarm - marie system]. For a ...longer list, see http://www.factmonster.com/ipka/A0768070.html The windshield wipers thing is preposterous as Mary Anderson is well-accreddited for creating the prototype. Okay, let me clarify because this is very important to me: Women invented the following, for starters: Bullet Proof vest, fire escape {Anna Connelly built the fire escape stairs in 1887}, windshield wipers [Mary Anderson], dishwasher, home security system [burglar alarm - marie system]. So yes, the LADDER was invented by him, but she was first to build the stairs (and prototype). I have to look up about the laser printer ...

Information about the fire escape is here: http://www.answers.com/topic/188 "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." Jan 07 10, 8:27 PM
