Walter Hunt invented this device in 1849 in a desperate three-hour burst of creativity to pay off a fifteen-dollar debt; he eventually sold the patent rights for just four hundred dollars.

The American inventor reportedly came up with it in about three hours, while twisting a piece of wire.
The ancient Romans used a related fastener called a fibula.
The legendary saviour of a wardrobe malfunction.
A self-locking guardian of loose fabric.
A bent wire that keeps things held together.
