I’m sure you’ve used the zipper many times. It can be seen almost everywhere today. But have you ever wondered who invented it?

Whitcomb Judson was an inventor. He had a friend who had a sore back. Judson’s friend couldn’t bend over to tie his shoes. So Judson designed what he called a “clasp locker(扣环)” for him. It could be opened and closed with one hand. He patented(取得专利权) the idea in 1891. Even though he started his own company to make the clasp locker, Judson didn’t make his invention famous.

The zipper as we know today is a result of the work of Gideon Sundback who worked as head engineer at Judson’s company. Sundback improved on Judson’s design. His design was stronger, faster and more reliable(可靠的) and Sundback patented it in 1917, calling it the “separable fastener(可分离扣)”. With World War One breaking out, the army used his design on its clothing and equipment for the soldiers.

However, the invention didn’t become popular with the public until 1923 when the B．F. Goodrich Company decided to use Sundback’s invention on their new shoes. A leader at the company named them zippers after the noise they made, and the zipper got its name from then on. It also caught the attention of fashion designers in France, who used zippers in men trousers.

The zipper not only makes it more convenient to fasten clothing. The invention of plastic zippers also helps in the fashion industry(行业). This small invention did change our life.
