"A similar yarn was told of Abraham Lincoln, which was equally false,
but even more generally believed.
"Out of a multitude of labor savers and world-beaters--and world savers,
too!--to be credited to Mr. Edison, it is impossible to mention more
than these:
"The quadruplex telegraph system for sending four messages--two in each
direction--at the same time; the telephone carbon transmitter; the
phonograph; the incandescent electric light and complete system;
magnetic separator; Edison Effect now used in Radio bulbs; giant rock
crushers; alkaline storage battery; motion picture camera. These are but
few of Edison's inventions, but they are giving employment to over a
million people and making the highest use of billions of dollars.
"With Mr. Edison's modesty it is difficult to get him to talk of the
relative importance of his inventions, but he has expressed the opinion
that the one of most far-reaching importance is the electric light
system which includes the generation, regulation, distribution and
measurement of electric current for light, heat and power. The invention
he loves most is the phonograph as he is a lover of music. He has
patented about twelve hundred inventions.
"Recent developments are proving that the moving picture, because of its
educational and emotional appeal is the greatest of them all. It is
estimated that more than one hundred millions of people go to one of
these shows once every seven days, which is equivalent to every man,
woman and child in the United States of America going to a movie once a
week.
