How long has the zipper been around?

The zipper, in its modern form, was patented in 1913 by Gideon Sundback, although earlier versions date back to the late 19th century. The first practical design was developed in 1893 by Whitcomb Judson, who called it the "clasp locker." Since then, the zipper has evolved and become a ubiquitous fastening device used in various applications, from clothing to bags.
