Transcript of Thomas Edisons Inventions of the Gilded Age

The Electric Generator
In 1882, Edison built on Michael Faraway's work from 1831. Faraway had discovered that if you move a conductor between two magnets, electrons flow freely. Edison took this principle and used it to make his generator. He used a crank to spin a coil between two magnets and then harnessed the electrons
The First generator went live at Pearl Strret Station at 3 PM on September 4th 1882. It supplied power for 4,400 lamps in 193 buildins. It stayed active for the next eight years.

The Tinfoil Phonograph
The tinfoil phonograph was the first method of recording sound. It used a needle to indent sound waves into a sheet of tin foil. Then you could spin the tinfoil back and it would play your recorded message.
The tin foil phonograph eventually evolved into the record player. The record player simply read the grooves of a vinyl disc instead of a tin foil cylinder. This also lead to digital music which was read by a laser measuring the depth of the grooves on the disc.
Thomas Edison was born on February 7th, 1847. He was the seventh child of Samuel Ogden Edison and Nancy Matthews Elliot. They were a middle class family living in Milan Ohio. Thomas had only three months of formal school before he dropped out due to his ADHD. He was home schooled the rest of his childhood. In 1876, Thomas opened a research facility in Menlo Park New Jersey. This is where many of his great inventions where created. It is also how he recived his nickname, "The Wizard of Menlo Park"
The Alkaline Storage Battery


Edison's Battery had neckelic oxide as the cathode material, positive material, and iron as the anode material, negative.
The invention of the alkaline battery made Edison create the "Edison Storage Battery Company". This company produced batteries for mining lamps, train lighting, submarines, and electric vehicles.
The Light Bulb


Here's a quick video about the light bulb
On October 22, 1879, Edison invented the first successful commercially practical incandescent light bulb by using a carbon filament or strip coiled and connected to platina contact wires.
Impact of all of Thomas Edison's Inventions
During the Gilded age, Thomas Edison completely changed the way of life for every American. There was a new alternative as opposed to candles, something never seen before.
Also, the phonograph was the first step to replicating sound for the telephone.
Finally, the electric generator changed the way electricity can be supplied to areas. With the generator, much larger areas could be supplied for all with one generator.
Without all of Thomas Edison's inventions, the world would not be the same at all. Everything he invented is still used today or influenced something that is used today, like the phonograph influencing the telephone.
