Zipper Day

Zipper Day is an annual American holiday dedicated to the zipper. Today, we zip up our favorite jackets and head out the door, enjoying the convenience that was once unavailable. Let’s explore the history of the zipper and how it transformed our lives for the better. The holiday is observed on April 29.

History

The exact origins of Zipper Day are unclear. According to historians, the zipper was first developed by Elias Howe in the 19th century. He received a patent for a device that could automatically join two pieces of fabric together. However, Howe did not market or distribute his invention, leaving it largely unknown.

Around the same time, a version of a shoe with a similar fastening mechanism was presented at the World’s Fair in Chicago, but it also failed to gain traction and became just a historical curiosity.

The zipper’s widespread popularity is credited to engineer Gideon Sundback, who patented his version on this day in 1913. A few years later, zippers began to be used in footwear and eventually in clothing. The zipper became especially popular with soldiers during World War I and soon spread worldwide, becoming an essential element in the clothing industry.
