The invention of the zipper is associated with both Whitcomb Judson and Gideon Sundback.


Although the concept of the zipper existed as early as the end of the 19th century, the work of these two inventors laid the foundation for its practicality and modernization.


The Early History of Zippers


The concept of zippers can be traced back to ancient times. Structures similar to zippers have been found on some decorations discovered in ancient Egyptian tombs.


However, these early devices were often handmade and impractical. It was not until the end of the 19th century that devices bearing some resemblance to modern zippers began to appear. Unfortunately, they had a series of problems, such as being easily damaged and inconvenient to operate.


Contributions from Whitcomb Judson


Whitcomb Judson is a key figure in the history of the invention of the zipper. Born in the United States in 1851, he was a prolific inventor and entrepreneur. Judson's work primarily focused on finding an innovative solution to the problem of fastening clothing.


In 1891, Judson received a patent for the "Clasp Locker." This device is considered an early prototype of the zipper, although it was quite different from modern zippers.


The Clasp Locker is operated by employing a complex mechanical system involving multiple hooks and eyes to secure the two sides of the fabric together. While it did address some issues, it was relatively complex, impractical, and lacked the convenience and reliability of modern zippers.


Judson later established a company known as "The Never Slip Slide Fastener Company" to promote and sell his invention. Though the initial product failed to achieve commercial success, it signaled the growing interest in zipper concepts within the engineering world.


Contributions from Gideon Sundback


Gideon Sundback, born in Sweden in 1880, immigrated to the United States, where he spent most of his career. Although he had earned a degree in electrical engineering, he later shifted his focus to the textile and clothing industry.


In the early 20th century, Sundback embarked on research to enhance zipper designs. He dedicated extensive effort to experimenting with various ideas, aiming to discover a more practical and reliable method for joining two pieces of fabric together. His breakthrough came in 1913 when he designed a new type of zipper.


Sundback's zipper design employed a series of interlocking metal teeth that could be connected or separated by a sliding slider. Key features of this design included:


Metal Teeth: Sundback's zippers used metal teeth, making them stronger and more durable. The design allowed these teeth to engage with each other when closed, ensuring a secure connection.


Sliding Slider: The sliding slider of the zipper was another crucial element in Sundback's design. The slider effortlessly moved along the zipper's path to connect or separate the teeth, resulting in a highly convenient and quick operation.


Reliability: Sundback's design significantly improved the reliability of the zipper, nearly eliminating common issues such as jamming, breakage, or inadequate fastening.


In 1914, Sundback obtained a patent for his zipper invention, referred to as the "separate link," which served as the prototype for the modern zipper. This new zipper design was not only more practical and reliable but also easier to manufacture and promote.


The history of the invention and development of the zipper involves the contributions of many inventors, with Whitcomb Judson and Gideon Sundback both playing pivotal roles.


Over time, zippers evolved and improved, becoming an integral part of modern life. This simple yet powerful mechanical device revolutionized the way clothing, footwear, and various other products were designed and manufactured, leaving a profound impact on modern industry and the fashion world.
