The original hook and loop fastener was conceived in 1941 by Swiss engineer George de Mestral. The idea came to him one day after returning from a hunting trip with his dog in the Alps. He took a close look at the burs (seeds) of burdock that kept sticking to his clothes and his dog's fur. He examined them under a microscope, and noted their hundreds of "hooks" that caught on anything with a loop, such as clothing, animal fur, or hair. He saw the possibility of binding two materials reversibly in a simple way if he could figure out how to duplicate the hooks and loops. Hook and loop is viewed by some like Steven Vogel or Werner Nachtigall as a key example of inspiration from nature or the copying of nature's mechanisms (called bionics or biomimesis).
The origin of the hook and loop is very simple, just from a small thing in life, but it really brings great convenience to our life!
