Stuck on a Solution: The Clunky Invention That Had to Nearly Die Before It Could Dress America

You've probably zipped something up already today without thinking about it once. A jacket, a pair of pants, maybe a bag. It's the kind of action the hands do on autopilot — fast, reliable, done. But the zipper almost never made it this far. For most of its early life, it was considered unreliable, impractical, and frankly kind of embarrassing to be associated with. The story of how it went from laughingstock to essential is really the story of one company's desperation and one designer's obsession with getting a broken idea to finally work.

The Invention That Kept Failing

The concept behind the zipper goes back to 1851, when Elias Howe — the same man who invented the sewing machine — patented something he called an "Automatic, Continuous Clothing Closure." Howe never actually developed it. He was busy with the sewing machine, which was already making him rich, and the clothing closure idea sat in the drawer.

It stayed there, more or less, until 1893, when a Chicago engineer named Whitcomb Judson showed up at the World's Columbian Exposition with a device he called the "Clasp Locker." It was designed to fasten boots and shoes without the hassle of hooks and laces. Judson's version worked on a slide-and-hook mechanism — two chains of metal hooks that a sliding clamp could connect or disconnect.

The problem was that it didn't work very well. The Clasp Locker had a habit of popping open at inconvenient moments, jamming unpredictably, and generally behaving like a prototype that needed another decade of development. The U.S. Postal Service placed a small order for mail bags, which was something, but consumer adoption was essentially nonexistent. The device was a curiosity, not a product.

The Man Who Refused to Quit

Enter Gideon Sundback, a Swedish-American electrical engineer who joined Judson's company — by then called the Automatic Hook and Eye Company — in 1906. Sundback had no particular background in fasteners. He was a trained engineer who had come to the U.S. to work, met and married the plant manager's daughter, and found himself increasingly absorbed by the problem of making this stubborn little device actually function.

When his wife died in 1911, Sundback threw himself into his work. Over the next few years, he redesigned the fastener almost entirely. His 1913 version — which he called the "Hookless Fastener" — replaced the old hook-and-eye system with interlocking teeth, a design much closer to what we recognize today. Each tooth had a small dimple on top and a corresponding nub on the underside, so that when the slider moved along the chain, the teeth locked together with real mechanical force. It held. It didn't pop open randomly. It could be manufactured consistently.

Sundback also designed the machine that could produce the fasteners at scale, which turned out to be just as important as the fastener itself. By 1917, he had a patent and a product that worked. What he didn't have was an industry willing to use it.

The Boot Company That Changed Everything

For years, the Hookless Fastener remained a niche item. It found modest use in tobacco pouches and money belts — functional objects where reliability mattered more than fashion. Clothing manufacturers weren't interested. Buttons worked fine. Buttons were familiar. Buttons didn't jam.

Then, in the early 1920s, the B.F. Goodrich Company came looking for a solution to a specific problem. Goodrich made rubber galoshes — the tall, pull-on boots that Americans wore over their shoes in winter. Getting them on and off was a tedious process involving multiple buckles and a fair amount of wrestling. Goodrich wanted something faster.

They found Sundback's fastener, saw what it could do, and placed a significant order. Goodrich's CEO, reportedly delighted by the "zip" sound the fastener made when operated, is widely credited with coining the name that stuck: the zipper. Whether that story is entirely accurate is debated by historians, but the branding decision was real, and it mattered. "Zipper" was catchy. It sounded fast and modern. It sounded like something you'd want on your boots.

The Goodrich galoshes with zipper closures sold. Consumers liked them. The fastener worked in actual conditions — mud, cold, daily use — and the word "zipper" started entering the American vocabulary.

From Boots to Everything Else

Even after the Goodrich success, the fashion industry held out for another decade. Clothing designers were skeptical, and there was a lingering cultural association between zippers and workwear or utilitarian products. The breakthrough into mainstream fashion came in the 1930s, driven in part by a deliberate promotional push.

In 1937, a fashion PR campaign — sometimes called the "Battle of the Fly" — made the case for zippers in men's trousers, arguing that they were more hygienic than buttons. It sounds absurd now, but the campaign worked. Men's trouser zippers became standard. Children's clothing followed, partly on the argument that zippers helped kids dress themselves more easily. By the 1940s, zippers were appearing in women's dresses, skirts, and jackets. The military used them extensively during World War II, which further normalized them in civilian life.

By the 1950s, the zipper was simply part of how clothes worked. The decades of failed prototypes, skeptical manufacturers, and slow adoption had been forgotten. All that was left was the sound — a quick, clean zip — and the assumption that it had always been this easy.

It hadn't. It took one engineer's grief-fueled obsession and one boot company's very practical problem to finally pull the thing together.
