The Telegraph
By: Dana Zahra
The Introduction Of The Telegraph
 The telegraph was invented by
Samuel F.B Morse in 1837 in the
New York University.
It took him 12 long years.
 The telegraph was used for
communication and transferring
information faster and it was heavily
used at wars, where they needed to
send commands and request for help
in emergency times.
In addition it was also used in
peoples social lives.
 Also the telegraph is used for
sending messages, news and any
urgent information.
People needed a faster way
to communicate and send
information and news.
Samuel F.B Morse
•Born on April 27, 1791 in Charlestown, Massachusetts.
•First son of Jedidiah Morse and Elizabeth Breese.
•At the age of seven he attended in Phillips Academy.
• He wasn’t a great student but he certainly had very good
drawing skills.
•Graduated from Yale College in 1810.
•Wanted to have a career in art, but his father disagreed to this.

• So instead Samuel took a job as a clerk in a Charlestown
bookstore, but still in that time he continued painting.
•His father changed his decision and in 1811 he allowed Morse
to travel to England to continue his art.
•Samuel worked at the Royal Academy with an American
artist Benjamin West.
•On 1818, he got married. His wife had two boys and one girl.
•Samuel invented the first Telegraph in 1837, it took him 12
long years.
•In April 1872, Samuel Morse died.

The Story Of The
On October 1832, Samuel Morse and
his family, sailed back home on a ship
called the Sully.
One day during his trip, he heard some
passengers talking about electricity.
He had an idea, he thought maybe
electricity could transmit messages.
So for the rest of the trip, he worked
on an alphabetical system that was
then called the Morse code. The
symbols he made up were the dot and
the dash.
When he got back home he started
making what he called a telegraph. It
was made out of picture frames, lead,
and wood from a table.
How The
Telegraph Works
The telegraph works by
electrical pluses which
transfer coded messages
through a wire to the other
end, where then the massage
is decoded into words.
How The Telegraph Solves The
The invention of the telegraph solved the problem
by sending messages and information much faster.
What Humans
Did About The
Problem Before
The Telegraph
Before the telegraph was
invented messages would
take months or even years to
reach. The Pony Express was
a mail company way back in
the 1860s. It was created to
deliver the mail faster. But
it still took long.
How The Telegraph
Improved Human Life
The Telegraph improved the way
people communicate, and they could
send messages quicker between cities
and even continents.
The Telegraph spread important
news, useful information and
emergency warnings faster. Knowing
this information people can react
Detail Changes Or Improvements Made
To The Telegraph Through Time
In 1580 operators realized that the clicks of the
recording instrument made a sound pattern. This
allowed the operator to hear the messages and write it
down. The telegraph became a more speedy system.
In 1871 the duplex telegraphy was invented. Two
messages were sent over the wire, one in each direction.
In 1883 an English automatic telegraph was invented. It
allowed larger numbers of words to be transmitted over
a wire at once.
Buckingham's Machine Telegraph printed received
messages in Roman letters on a paper.
In 1890 the Vibroplex was invented. It has a automatic
key called the bug key which made the dots

How Has The Telegraph
Created New Problems
For Us
•People needed to build
telegraph stations and trained
many operators.
•People needed to lay cable
wires between many cities,
even continents.
•Nowadays the telegraph
doesn’t make any problems for
us. It had been replaced by the
radio, the newspapers,
television and the internet.
The television and the internet
might have bad influence on
people. We need to be aware
on what based our decisions,
beliefs and values.
Timeline Of The History Of
The Telegraph
In 1794 Claude Chappe invented the non-electric telegraph.
In 1809 Samuel Soemmering invented a telegraph that used electrodes in
In 1828 Harrison Dyar invented telegraph that sent electrical sparks
through chemically treated paper tape.
In 1825 William Sturgeon invented the electromagnet.
In 1830 Josef Henry used the electromagnet to send the signal.
In 1837 William Cooke and Charles Wheatstone made the telegraph
based on electromagnetism.
In 1837 Samuel Morse successfully used the electromagnet and invented
a telegraph system that had practical success.
The telephone (1849) and the radio (1897) were the new inventions that
replaced the telegraph.
