John Wesley Hyatt

Why is Hyatt important?

Hyatt, a printer, combined camphor, alcohol and gun cotton, compressed it into billiard balls Hyatt, a printer, combined camphor, alcohol and gun cotton, compressed it into billiard balls The material was called “celluloid” The material was called “celluloid” Great stuff, except Great stuff, except

They had an unfortunate tendency to explode – after all, they were made of gun cotton.

Hannibal Goodwin Took the celluloid invented by Hyatt and turned it into sheets Took the celluloid invented by Hyatt and turned it into sheets

George Eastman Took Goodwin’s celluloid sheets and turned them into strips These strips are called film

Etienne Jules Marey Added sprocket holes to the edge of film in order to pull it through the projector The first movie projector using strips of pictures instead of disks

Thomas Alva Edison

All this was fine, but soon the novelty wore off. More was needed.

George Méliès

Méliès

Melies and others followed the Lumieres and showed movies in theatres. They were called “Nickelodeons” – odeon from the Greek for theatre, and nickel for what patrons paid to watch the movies.

Edison jumped on the bandwagon.

The Great Train Robbery

Again, the novelty soon wore off. The time had come for longer films – two and three reelers instead of one-reelers, like D.W. Griffith’s “Birth of a Nation”

You may have noticed something

No sound

Edison tried adding sound by combining his kinetoscope and his kinetophone, showing the film while playing the sound.

The major problem was synchronization

Remember the telephone – How sound could be converted to electrical impulses

Changing the amplitude of an electrical current can cause a light to brighten or dim in direct relation to the amount of electricity.

Danish researchers – Discovered selenium would generate an electrical signal in direct relation to the amount of light shining on it.

Exposing film to the flickering light created by sound, then putting it on one side of the film created the sound track.
