Thomas Alva Edison        USA        1847-1931

Edison invented

or refined devices

that made a profound impact

on how people lived.

The most famous

of his inventions

was the incandescent

light bulb

(1878),

which would revolutionize

indoor lighting

and forever separate

light from fire.

He also developed

the phonograph

(1877),

the central power station

(1881),

the motion-picture studio

(1892)

and system for making

and showing motion pictures

(1893),

and alkaline storage batteries

(1901).

Edison

improved upon

the original designs

of the stock ticker,

the telegraph,

and Alexander Graham Bell's

telephone.

He was one

of the first

to explore X-rays,

and in 1875,

he announced

his observation

of "etheric force"

-- radio waves --

although his claim

would be rejected

by the scientific

community.
