Thomas Alva Edison is born in Milan, Ohio in 1847. He was said to be a scientist and an inventor. He
would not only see great changes in his life time, but would be the cause of that change in man. He may more
responsible for the birth and rise of the entertainment business than any man in history. When he was born,
society looked at electricity as a fad and somewhat a novelty. He was known as "The Wizard of Menlo Park."Edison was issued 1,093 patents, more than any other inventor in history. Below
is a list of a few of his major inventions.

Edison explained the idea behind the phonograph in the following excerpt from the
June,1888 issue of the "North American Review":"To make the general idea of the recording of sound more clear, let me remark one or two points.
We have all been struck by the precision with which even the faintest sea-waves impress upon the
surface of a beach the fine, sinuous line which is formed by the rippling edge of their advance.
Almost as familiar is the fact that grains of sand sprinkled on a smooth surface of glass or wood,
on or near a piano, sift themselves into various lines and curves according to the vibrations of the
melody played on the piano-keys. These things indicate how easily the particles of solid matter
may receive an imparted motion, or take an impression, from delicate liquid waves, air waves, or
waves of sound. Yet, well known though these phenomena are, they apparently never suggested
until within a few years that the sound-waves set going by a human voice might be so directed as
to trace an impression upon some solid substance, with a nicety equal to that of the tide in
recording its flow upon a sand beach."
