Transcript of 1889 World's Faire: Modern Technology

Alexander Graham Bell's Telephone
The first telephone was displayed at the 1889 World's Fair. Like other inventions of the day, it benefited from innovations in the field of electricity. It essentially transmitted the human voice over an electrical current. The first transmitted message, stated famously by Bell, was reportedly, “Mr. Watson, come here; I want you.” The telephone brought fast, personal, and affordable communication to the public, revolutionizing communication technology.
Electric Phonograph
Invented in 1877 by Thomas Edison
Records and reproduces sound
Sound vibrations taken from a record
Playback stylus records the sound
Horn plays back the sound much louder
Chemical Battery
-Invented by Alessandro Volta in 1800.
-Device that transforms chemical energy into electrical energy. An electrical circuit runs between two electrodes on either end of the battery while traveling through a chemical called electrolyte.

Edison's Motion Picture Machine
At the World's Fair, Thomas Edison screened the first motion picture in history, ushering the new art form of "moving pictures." The actual name of the machine was the Kinetophone. The first film was of a man playing the violin while two others danced. By combining this with the phonograph, people could combine sound and moving pictures, foreshadowing the invention of the "talkies."
