Garrett A. Morgan
Garrett Morgan was born on March 4, 1877. He was a man who used his curiosity to invent many products of which many are still being used today. Morgan spent his life trying to make lives of the common people safer. Of these inventions that he created to make people’s lives safer the most important are the 3position traffic light and the gas mask. Chemical warfare began in Germany on April 22, 1915, when chlorine gas was used to attack the French. There wasn’t any way to protect against the chlorine gas before. Not only did the French need a mask that will provide breathable air, so were miners, divers, and firemen. The first “Gas Mask” was invented by Lewis Haslett and he made an inhaler, or lung protector. After Lewis, a Scottish chemist named John Stenhouse invented a mask that used charcoal to filter noxious fumes. In 1860, Frenchmen, Benoit Rouquayrol and Auguste Denayrouse invented the Reservoir-Regulator, intended for use in rescuing miners in flooded mines, the Reservoir-Regulator could be used underwater. The device was made up of a nose clip, and a mouthpiece attached to an air tank that the rescue worker carried on his back. American, Garrett Morgan patented the Morgan safety hood and smoke protector in 1914. Two years later, Garrett Morgan made national news when his gas mask was used to rescue 32 men trapped during an explosion in an underground tunnel 250 feet beneath Lake Erie. The publicity sold the safety hood to firehouses across the United States. The Morgan design was used as the basis for early U.S. army gas masks used during WWI.
When the first cars came out, there was no 3 position or 4 position traffic lights to control traffic flow. There was a revolving lantern with red and green signals. Red meant "stop" and green meant "go." The reason they chose red and green was because red was because red attracted a lot of attention and it heightens nervous tensions in people. They chose green because green has a...
