Sometime in the year 1948, Swiss engineer Georges de Mestral, as so often, went hunting with his Irish pointer. Afterwards, as so often, he was annoyed by the tangles that clung to his pants and socks and especially to his dog's coat. Cleavers is a plant that has thousands of small hooks to spread its seed on the seed pods. It is an intelligent plant that spreads its seed efficiently. And over and over again, the Mestral had to pick the nasty little balls from his dog's coat.
