Everyone thinks it was Whitcomb Judson who invented the zipper but it was Elias Howe.
Elias was so busy inventing the sewing machine that he didn't get around to selling his zipper invention which he called a "clothing closure".
The zipper is used everywhere, on clothing, pencil cases, boots and suitcases, wallets, and many other things.
Do you know the name of the tallest woman in the world?
