"What
hath God wrought!" was the first public message sent by Samuel
Finley Breese Morse in 1844 over his single-wire telegraph, which
was modified from the traditional five-wire device. Morse
developed a 'language' that translated letters of the alphabet and
numerals into individual code symbols. He subsequently
invented a 'sounder device' that could be heard as well as read on
paper. This dots and dashes communication system would
become known as Morse Code.
Morse was told of electromagnets in 1832 and spent three years trying
to invent a telegraph based on electromagnetism. In 1835
he built his first device consisting of an electromagnet pendulum
carrying a pencil in constant contact with a moving strip of paper. His
partner, Alfred Vail, suggested a device with a lever on one end and
an armature at the other. Vail agreed to build this device
by modifying Morse's and secured American and foreign patents.
The code printed from the first telegraphs had its readability problems,
so Vail continued to modify the invention and eventually restructured
the device from the ground up. With those significant changes
came a new code much different than Morse's original version. It
was actually Vail who introduced the world to the modern version of
Morse Code.
By the 1850s, telegraph lines crossed Europe and spanned the United
States. In the mid 19th century, the final frontier in Morse Code
was to lay a cable under the sea. In 1847 Michael Faraday
presented a water-proof solution for insulating electrical wires with
a latex-type extract known as Gutta-percha. After several
failed attempts and improvements, the first underwater, international
telecommunications device opened to the public on September 18, 1866.
With the aid of the first amplifier, a Marine Galvanometer, mirrors
and light allowed the faint electrical impulses sent 1,852 miles to
be read.
