was first invented by Whitcomb Judson, in 1893. however it's just happend not to be called a zipper. Back then it was called, "Clasp Locker"....so weird. "With businessman Colonel Lewis Walker, Whitcomb launched the Universal Fastener Company to manufacture the new device. The clasp locker debuted at the 1893 Chicago World's Fair and was met with little commercial success."
After that the new fashion trend was the...Zipper! Everyone, meaning every company promoted the zipper, in children clothing, boots tobacco pouches, men pants, etc. Later on the next big boost for the zipper came when devices that open on both ends arrived, such as on jackets. Today the zipper is everywhere, in clothing, luggage, leather goods and countless other objects. Thousands of zipper miles are produced daily to meet the needs of consumers, thanks to the early efforts of the many famous zipper inventors.
