Velcro Patented
Swiss engineer George de Mestral patented Velcro after observing how burrs attached to his dog
October 13, 1955
Burrs in the Woods, Idea in the Lab
In 1941, Swiss engineer George de Mestral returned from a walk in the Alps with his dog and found his trousers and his dog's fur covered in burr seeds. Curious about why they clung so stubbornly, he examined them under a microscope and discovered that each burr was covered in tiny hooks that caught on the loops of fabric or fur. The insight was immediate: if he could recreate this hook-and-loop system artificially, he could make a new kind of fastener. It took eight years of experimentation to develop a workable product, and Velcro was patented in 1955.
From Fashion Failure to Space Age Success
Velcro's early commercial history was rocky. De Mestral struggled to find manufacturers willing to invest in the technology, and initial fabric versions were seen as inferior to zippers for clothing. The product found its first major customer in the aerospace industry — NASA used Velcro extensively in the Apollo program to secure equipment in the weightless environment of spacecraft. Astronauts used it to anchor food packets, tools, and other items that would otherwise float away. The association with space travel gave Velcro a futuristic image that helped its eventual consumer market acceptance.
Everywhere You Look
Today Velcro — technically a brand name; the generic term is "hook-and-loop fastener" — is found on shoes, clothing, medical devices, luggage, military equipment, and thousands of industrial applications. The original patent expired in 1978, opening the market to many competing manufacturers. The global hook-and-loop fastener market is worth billions of dollars annually. De Mestral's story is a classic example of biomimicry — learning from nature to solve engineering problems — a field that has since produced many other innovations. Compare it with the similarly accidental discovery behind the microwave oven.
