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.
Rubber glove
In 1889, William Stewart Halsted, the first chief of surgery at Johns Hopkins Hospital, invented rubber gloves in order to prevent medical staff from developing dermatitis from surgical chemicals.
