Velcro
Swiss electrical engineer George de Mestral invented his first touch fastener when, in 1941, he went for a walk in the woods and wondered why Burdock seeds clung to his coat and dog. He discovered it could be turned into something useful. He patented it in 1955 and subsequently refined and developed its practical manufacture until its commercial introduction in the late 1950s.
Vacheron Constantin
François Constantin traveled around the world and marketed watches. The main market was North America. In 1833, Vacheron and Constantin hired Georges-Auguste Leschot, whose job was to supervise the manufacturing operations. In particular, Leschot was an inventor and his creations turned out to be successful for the company. His inventions had significant impact on the watchmaking industry in general, and he was the first person to standardize watch movements into Calibers. In 1844, Georges-Auguste Leschot was awarded with a gold medal from the Arts Society of Geneva, who highly appreciated Leschot's pantographic device - a device that was able to mechanically engrave small watch parts and dials.
