History

The exact birthday of the zipper is rather up for debate because, instead of being “born” on a particular day, it sort of evolved over time.

National Zipper Day is celebrated as a not to the date of April 29, 1913. On that day, Swedish-American scientist and inventor Gideon Sundback received a patent for this curious contraption he called “hook-less fastener”.

Although similar inventions had been around since the 1850s, his version is widely accepted as the first modern zipper.

The name “zipper” seems to have made its way into common use due to a set of rubber boots that the fastener was used on in 1923. Marketed as galoshes that could be easily fastened with a single zip of the hand, and mirroring the sound that the fastener tends to make, the name “zipper” emerged and has stuck for a century.

The continuous fastening line found numerous applications and grew in popularity, also thanks to the US Army who stepped in as an early adopter. Functional, fashionable, infinitely adjustable – these qualities of Sundback’s design have helped popularize the invention and practically make every day National Zipper Day.

National Zipper Day offers a special opportunity to show appreciation for this humble, everyday convenience that is mostly taken for granted!
