Gideon Sundback of Hoboken, N.J. patented the zipper this date in 1913.
A zipper, zip-fastener, formerly known as a clasp-locker, is a commonly used device for binding the edges of an opening of fabric or other flexible material, like on a garment or a bag. It is used in clothing (e.g., jackets and jeans), luggage and other bags, sporting goods, camping gear (e.g. tents and sleeping bags), and other items. The method, still in use today, is based on interlocking teeth. Initially it was called the “hookless fastener” and was later redesigned to become more reliable. The word Zipper is onomatopoetic, because it was named for the sound the device makes when used, a high-pitched zip.
The popular North American term zipper came from the B. F. Goodrich Company in 1923. The company opted to use Gideon Sundback’s fastener on a new type of rubber boots (or galoshes) and referred to it as the zipper, and the name stuck. The two chief uses of the zipper in its early years were for closing boots and tobacco pouches. Zippers began being used for clothing in 1925 by Schott NYC on leather jackets.
In the 1930s, a sales campaign began for children’s clothing featuring zippers. The campaign praised zippers for promoting self-reliance in young children by making it possible for them to dress in self-help clothing. The zipper beat the button in 1937 in the “Battle of the Fly,” after French fashion designers raved over zippers in men’s trousers. Esquire declared the zipper the “Newest Tailoring Idea for Men” and among the zippered fly’s many virtues was that it would exclude “The Possibility of Unintentional and Embarrassing Disarray.” (from Wikipedia)
