This is the story of talking at a distance, of sending
messages through space. It is the story of great
men—Morse, Thomson, Bell, Marconi, and others
—and how, with the aid of men like Field, Vail,
Catty, Pupin, the scientist, and others in both the
technical and commercial fields, they succeeded in
flashing both messages and speech around the
world, with wires and without wires. It is the story
of how the thought of the world has been linked
together by those modern wonders of science and
of industry—the telegraph, the submarine cable,
the telephone, the wireless telegraph, and, most
recently, the wireless telephone.
The story opens with the primitive methods of
message-sending by fire or smoke or other signals.
The life and experiments of Morse are then
pictured and the dramatic story of the invention
and development of the telegraph is set forth. The
submarine cable followed with the struggles of
Field, the business executive, and Thomson, the
inventor and scientific expert, which finally
culminated in success when the Great Eastern
landed a practical cable on the American coast.
The early life of Alexander Graham Bell was full of
color, and I have told the story of his patient
investigations of human speech and hearing,
which, finally culminated in a practical telephone.
There follows the fascinating story of Marconi and
