Just over fifty years ago, the Velcro® trademark was registered.

It all began with Swiss engineer George de Mestral’s 1941 hunting trip in Switzerland. While walking his dog in the mountains, de Mestral accidentally brushed up against some cocklebur plants, and by the time he got back home, dozens of the round, spiky seeds were clinging to his wool trousers (and his poor dog’s fur).

The engineer quickly figured out why the seeds were so sticky by examining them under a microscope; the spikes each ended in tiny hooks that grabbed onto fabric and fur and wouldn’t let go. But it wasn’t until 1952 that de Mestral made a serious effort to mimic the cockleburs’ hooks using different types of fabric. He quit his day job and raised $150,000 in venture capital, an enormous sum at the time. He also joined up with a textile weaver from France, the only weaver who thought the idea would actually work. The pair’s first attempt, using cotton, was a failure. But nylon, sewn into tiny hooks under bright infrared light, worked much better. He dubbed it “Velcro” after “velvet” and “crochet,” the French word for “hook.”
