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.
Clothes hanger
Some historians believe President Thomas Jefferson invented a forerunner of the wooden clothes hanger. However, today's most-used hanger, the shoulder-shaped wire hanger, was inspired by a coat hook that was invented in 1869 by O. A. North of New Britain, Connecticut. An employee of the Timberlake Wire and Novelty Company, Albert J. Parkhouse of Jackson, Michigan has also been credited with the invention. The story goes that one morning in 1903, Parkhouse arrived to work to find that all coat hooks were taken. Annoyed, he took a piece of wire, bent it into the shape we would recognize today, and hung his coat. Also credited is Christopher Cann in 1876 as an engineering student at Boston University.
