  5 History The story beginswhen Elias Howe, Jr. (1819–1867), inventor of the sewing machine, who received a patent in 1851 for an "Automatic, Continuous Clothing Closure." It didn't go much further beyond that, though. Perhaps it was the success of the sewing machine, that caused Elias not to pursue marketing his clothing closure system. As a result, Howe missed his chance to become the recognized "Father of the Zip." Forty-four years later, inventor Whitcomb Judson (1846–1909) marketed a "Clasp Locker" device similar to system described in the 1851 Howe patent. Being first to market, Whitcomb got credit for being the "inventor of the zipper." However, his 1893 patent did not use the word zipper. The Chicago inventor's "Clasp Locker" was a complicated hook- and-eye shoe fastener. Together with businessman Colonel Lewis Walker, Whitcomb launched the Universal Fastener Company to manufacture the new device. The clasp locker debuted at the 1893 Chicago World's Fair and was met with little commercial success.
