Inventions during the War

Morgan's device was known as the 'safety hood and smoke protector' and was a forerunner to the gas masks used in the war. He also invented the traffic signal and a zig-zag stitching device for sewing machines. All this from a man whose parents were slaves

An executive of the company which developed Pyrex said, "...we had a number of prior trademarks ending in the letters ex.

The first electric toaster was invented in Britain by Crompton and Co in 1883. However, it toasted only one side of the bread at a time and needed to be watched in order to stop the toast from burning. Strife's design was a vast improvement

Seiichi Kito, also of Los Angeles, and Makoto Hagiwara of San Fransisco both say that they invented the fortune cookie and dispute the Hong Kong Noodle Company's claim.

Sheffield is now famous for its stainless steel manufacture, as a look at a typical cutlery set will attest. Brearly marketed his new invention as 'Staybrite'

The 'clasp locker' had been invented in the 1800s by Whitcomb Judson and was itself a development of the 'automatic, continuous clothing closure' invented by Elias Howe.

De Forest was the first to use the term 'radio' and it caught on, replacing the older phrase, wireless telegraphy
