The Incandescent Lamp
Most people know Thomas Edison for his incredible invention of the light bulb, but did you know that he wasn't the one who invented it? The first person to invent the light bulb was Humphrey Davy. Thomas Edison created a new and improved version of the lightbulb called the incandescent lamp. The incandescent lamp wasn't his only invention. Edison patented 1,093 inventions!

The electric vote recorder was made with the goal of helping legislators in the US Congress record their votes in a quicker fashion than the voice vote system. It was useful because it made voting faster and more reliable.
Timeline of Thomas Edison's Life and Achievements
Feb. 11, 1847

Thomas Alva Edison was born in Milan, OH.


Edison became telegraph operator for Western Union when he was 19
June 1st, 1869

Edison patented his first invention, the electric vote recorder.
The Phonograph
Another famous invention of his was the phonograph. The phonograph was the first machine to produce recorded sound.
How does the Phonograph Work?
The phonograph's receiver consisted of a tin foil wrapped cylinder and a very thin membrane, called a diaphragm. The diaphragm was attached to a needle. Sound waves were directed into the diaphragm, making it vibrate. This vibration produced sound.
What is the EVR?
I promise I won't list all 1,093 of Edison's patents, but let's take a look at just one more.
What is the Kinetoscope?
The Kinetoscope was an early version of a video camera or movie player. The Kinetoscope was designed for films to be viewed by only one person at a time
through a peephole
at the top of the
How Did the Kinetoscope Work?
How does the Incandescent Lamp Work?

The incandescent light bulb or lamp is a source of electric light that works by incandescence, which is the emission of light caused by heating the filament.
How is the Incandescent Lamp Useful to Us Today?
Without Edison's incandescent lamp invention, we would be in the dark... LITERALLY! We rely on lights in
every situation. Because of his invention, we can light up our homes and other buildings such as offices, stores, schools, etc.
How is the Phonograph Useful to Us Today?
The phonograph has been improved and turned into many different sound devices since Edison invented it in 1877. For example, it has been changed into the record player, the radio, and the speaker.
How Did the EVR Work?
Edison's vote recorder was used by having each voter move a switch to either a yes or a no position. Then a signal was transmitted to a central recorder that listed the names of the voting members in two columns of metal type headed "Yes" and "No."

Congress was not interested in speeding up the voting process and Edison's vote recorder was never used!
What is the Kinetoscope now?
The kinetoscope was invented in 1891. It was later updated into a movie camera.

Electric Vote Recorder
A strip of film was passed quickly between a lens and a light bulb. Behind the peephole, a spinning wheel with a slit for a shutter flashed 46 frames per second. This made people and objects appear to move.
