953 nut 59,463 #1 Posted April 29 National Zipper Day is on April 29 and we are full of zip for this day! We take many things in life for granted and the humble zipper is one of them. Have you ever paused to reflect on how zippers play a huge role in our daily lives? Zippers come in apparel, purses, boots, etc. and are incredibly useful. A Swedish-American electrical engineer employed at Universal Fastener, Gideon Sundback, is credited with designing the modern zipper. He got the first patent for a “Hookless Fastener” on April 29, 1913, which was later developed into the “Separable Fastener”. It took a while to become popular as it was mostly a shoe fastener in the beginning after which the military started using the device during World War 1 for flying suits. Some manufacturers even used the device on tobacco pouches. Nevertheless, it was precisely a decade after this device received its first patent, that it would actually be called the ‘zipper’. The term was coined by B.F. Goodrich in 1923 because of the sound it made. 1 3 Share this post Link to post Share on other sites
