Zipper
An early device similar to the zip, 'an Automatic, Continuous Clothing Closure', was patented in the USA by Elias Howe in 1851, but did not reach the market.  Whitcomb Judson patented a similar 'Clasp Locker', for fastening shoes, in 1891 or 1893, and marketed the invention through his 'Universal Fastener' company.  These two designs used hooks and eyes.  The design used today, based on interlocking teeth, was invented by an employee of Judson's, Swedish scientist Gideon Sundback, in 1913 as the 'Hookless Fastener' and patented in 1917 as the 'Separable Fastener'.  The B. F. Goodrich Company coined the name 'Zipper' in 1923, and used the device on tobacco pouches and boots.  The zip became popular for children's clothing and men's trousers in the 1920s and 1930s.  At this stage, the zip was permanently joined at one end, so could not be used to fasten jackets.
