The great scientist Thomas Edison
Presentation by
Roshni hadi
Class : 10th A
Thomas Alva Edison (February
11, 1847 – October 18, 1931) was an
American inventor and businessman.
He developed many devices that
greatly influenced life around the world,
ncluding the phonograph, the motion
picture camera, and the long-lasting,
practical electric light bulb.
One day Thomas Edison came home and gave a paper
to his mother. He told her, “My teacher gave this paper to
me and told me to only give it to my mother.”
His mother’s eyes were tearful as she read the letter
out loud to her child: Your son is a genius. This school is
too small for him and doesn’t have enough good teachers
for training him. Please teach him yourself.
After many, many years, after Edison’s mother died
and he was now one of the greatest inventors of the
century, one day he was looking through old family
things. Suddenly he saw a folded paper in the corner of a
drawer in a desk. He took it and opened it up. On the
paper was written: Your son is addled [mentally ill]. We
won’t let him come to school any more.
Edison cried for hours and then he wrote in his
diary: “Thomas Alva Edison was an addled child that, by a
hero mother, became the genius of the century.”
A short story of Edison Mother
Most famous invention
By
Thomas Edison
The inventor Thomas Alva Edison (in
the USA) experimented with thousands
of different filaments to find just the
right materials to glow well and be long-
lasting.
In 1879, Edison discovered that a
carbon filament in an oxygen-
free bulb glowed but did not burn up for
40 hours.
History. David Edward
Hughes invented a carbon microphone in the
1870s. The first microphone that enabled
proper voice telephony was the (loose-
contact) carbon microphone (then
called transmitter). This was independently
developed by David Edward Hughes in England
and Emile Berliner and Thomas Edison in the US.
The Quadruplex telegraph is a
type of electrical telegraph which
allows a total of four separate
signals to be transmitted and
received on a single wire at the same
time (two signals in each
direction). Quadruplex telegraphy
thus implements a form of
multiplexing.
PHONOGRAPH
The phonograph was invented in 1877 by Thomas
Edison.
While other inventors had produced devices that
could record sounds, Edison's phonograph was
the first to be able to reproduce the recorded sound.
His phonograph originally recorded sound onto a
tinfoil sheet wrapped around a rotating cylinder.
MOTION PICTURE CAMERA
It was to provide a visual accompaniment to the
phonograph that Edison commissioned Dickson, a
young laboratory assistant, to invent a motion-
picture camera in 1888.
Dickson's camera, the Kinetograph, initially
imprinted up to 50 feet (15 metres) of celluloid film at
the rate of about 40 frames per second.
ELECTRIC POWER DISTRIBUTION
Swan and Edison later set up a joint
company to produce the first practical
filament lamp, and Edison used his direct-
current system (DC) to provide power to
illuminate the first New York electric street
lamps in September 1882.
MEMEOGRAPH
Thomas Edison is credited with inventing
the first mimeograph copying system.
Dick, whose company licensed Edison's
technology, invented the mimeo stencil and
marketed the first commercial mimeograph in
1887.
 Once text is cut (or typed) into the stencil, the
stencil is wrapped and fastened around a
cylinder
he failed over 1,000 times in trying to find the
right filament for his light bulb. That he
acknowledged openly. But he also tried any
number of other experiments, failing miserably
often, so I'm not sure there's a complete
count. He, like most other successful
inventors and entrepreneurs, knew that failing
was the road to success, and wasn't afraid of
doing so or trying things outside the box.

THOMAS EDISON DEATH
Death. Edison died of complications of
diabetes on October 18, 1931, in his home,
"Glenmont" in Llewellyn Park in West Orange,
New Jersey, which he had purchased in 1886 as
a wedding gift for Mina.
He is buried behind the home.
Edison's last breath is reportedly contained in
a test tube at the Henry Ford Museum.

This school is too small for him and doesn’t have enough good teachers for training him. Please teach him yourself. After many, many years, after Edison’s mother died and he was now one of the greatest inventors of the century, one day he was looking through old family things. Suddenly he saw a folded paper in the corner of a drawer in a desk. He took it and opened it up. On the paper was written: Your son is addled [mentally ill]. We won’t let him come to school any more. Edison cried for hours and then he wrote in his diary: “Thomas Alva Edison was an addled child that, by a hero mother, became the genius of the century.” A short story of Edison Mother
