Do you know the history of ZIPPER? An engineer named Whitcomb Judson invented the zipper in 1891. Judson's version consisted of hooks and eyes joined by a moving slide. Later inventors substituted two rows of interlocking teeth for the eyes and hooks. A wedge forces the teeth together or apart. Back then, the general public wasn't convinced to accept the zipper as part of everyday costume. The magazine and fashion industry made the novel zipper the popular item it is today, but it happened nearly 80 years after the zipper's first appearance.
