The invention of the zipper was actually a necessity. Before World War I, people tried to close their clothes with a button that was large and difficult to close. Although it is difficult to mention a single inventor in the invention of the zipper, it can be said that the main contribution was made by Whitcomb L.Judson, a mechanical engineer from Chicago in 1893. Judson was studying tram and automobile developments in those years and making successful inventions. In 1891 Judson came up with the invention of the unlocking (binder) for shoes.
