Google’s latest doodle, a giant zipper running down the centre of the search engine’s homepage, marks the birthday of Gideon Sundback, the Swedish-American electrical engineer most commonly associated with the development of the fastening device that revolutionised the clothing industry – Zipper!!
Before Sundback’s intervention, the idea for a fastener based on interlocking teeth had circulated among engineers for more than 20 years but no one had perfected it. His innovation was to place a dimple on the underside of each tooth and a nib on the top that would sit securely within the dimple of the tooth above it. As a result, the join between two rows of teeth was then strong because no single tooth has enough room to move up or down and come apart. He also created the manufacturing machine for the new zipper.

The name zipper was created in 1923 by B.F. Goodrich, who used the device on their new boots. Initially, boots and tobacco pouches were the primary use for zippers; it took another twenty years before they caught on in the fashion industry. About the time of World War II the zipper achieved wide acceptance for the flies of trousers and the plackets of skirts and dresses. (Source – WikiPedia)
