Scientific Accomplishments


Edison created the first phonograph in 1877. This invention played recordings that could be replayed over and over. The prototype used tinfoil wrapped around a cylinder and could only be played a few times, but inventors like Alexander Graham Bell would perfect this marvel.

Edison also invented the carbon microphone which was used in phones until recently in the 1980's.

One of Edison's most renowned inventions was the incandescent light bulb. This light source worked by heating a filiment inside a glass covering until it glowed producing a light that would last much longer than candle light.

The kinetograph was another invention of Edison's that allowed one viewer at a time to look into a box that showed a short film .

Another invention of Edison's was the Electrographic vote recorder. This contraption was used to make recording votes easier for legislators. A voter would turn the switch to their desired vote and an electric current would be sent to a desk where wheels kept track of the votes.

Edison also invented many things in his time to benefit everyday life and large industries such as a magnetic iron ore seperator, a fruit preserver, an electro magnetic brake, many railroad marvels, and many more small electric achievements that could be used by ordinary people.
