The earliest type of zipper was invented in 1891 by Whitcomb L. Judson. Called the clasp locker, it was an assemblage of hooks and eyes that Judson thought would save people time and sore backs fastening their shoes with one hand.
Later, in 1913, the predecessor of today's zipper that used metal teeth, and patented it in 1917 in Sweden. Later, the B.F. Goodrich Co. used the separable fastener in some rubber boots and came up with the name "zipper" because the boots could be fastened with one hand.
Now look at your own zipper: See the initials YKK? It stands for Yoshida Kogyo Kabushibibaisha, the world's largest zipper manufacturer that was started in Japan in 1934.
