2. ** Born: March 3, 1847 in
Edinburgh, Scotland
** Parents: Alexander Melville
Bell and Elisa Grace
Symonds
** Siblings: 2 brothers, Melville
and Edward
** Wife: Mabbel Hubbard Bell

3. In 1870, Bell’s two brothers died of tuberculosis. Since Bell was also
threatened his family decided to move to a healthier environment, Canada.

4. While Bell was in Massachusetts, he invented the harmonic
telegraph, an instrument that makes it possible to send
multiple telegraphs on one line.

5. On March 7, 1876, Bell recieved his patent for the telephone.
On March 10, 1876, Alexander Graham Bell was in his testing room with his
partner, Watson.
Mr. Watson--Come
here--I want to see
you.”

6. The experiment they were working with had reeds that were thin and steel.
One of the reeds was stuck so Watson plucked it to try to fix it.
When he did, Graham heard the vibration clearly through the newly invented
‘telephone’.

7. The Simple Telephone
There are three parts to the simple telephone. The Speaker, the
Microphone and the Switch, also known as the Hook Switch.

8. The telephone may seem like a complicated machine, but it really is one of
the simplest devices that you may find in your home, or anywhere else you can
imagine.
Today, phones have been able to get even smaller and even have no cords.
In the bottom left, there is a palm pilot that can also be used at a phone. The
telephone is a unique piece of equipment. No one can imagine our world without
it.

9. On August 2, 1922, Alexander Graham Bell died at his home
in Baddek Nova Scotia because of diabetes complications.

10. 1. Bell picked out his middle name himself.
Around the time of his 11th birthday, he decided to become Alexander Graham Bell
instead of just Alexander Bell. Perhaps he was tired of being the third Alexander in the
family, sharing this first name with his father and grandfather. Whatever reason for the
addition, Bell drew inspiration from one of his father's former students, Alexander Graham,
to add "Graham" to the mix. Bell may have liked the ring of his new moniker, but he was
still known to his family as simply "Alec" or "Aleck."
FACTS ABOUT ALEXANDER GRAHAM BELL

11. 2. After the telephone, Bell went on to develop an array of interesting inventions.
Bell created the photophone, which used light to transmit sound. Bell considered it to be
one of his greatest inventions. He also used his gift for inventing to solve problems. After
the death of his infant son in 1881, Bell made a metal vacuum jacket to help with breathing.
This idea influenced the design of the iron lung device used to aid polio patients in the
1950s. When an assassin shot President James Garfield in 1881, Bell was asked to help the
ailing leader. He came up with an electromagnetic machine to detect where the bullet was
lodged in Garfield's body. It failed at this task (Garfield later died), but the device was a
precursor to the modern metal detector.
