2. Do you love your cell phone, movies or
your digital camera? Thomas Edison
invented early versions of these
modern marvels. He also invented
the electric light bulb. Imagine how
different life was before his
inventions!
3. Thomas Edison was born in 1847 in
Milan, Ohio. He was a busy, curious boy
who got into trouble at school. His
teacher called him slow and when he
was seven he finally lost his patience
with his constant questions. Edison’s
mother decided to teach him at home
and let him set up a lab in the basement.
5. Edison patented 1,093 inventions
in his lifetime but the light bulb is
his most famous.
6. In 1879, after 1,200 experiments, Edison
made a light bulb using carbonized
filaments from cotton that burned for two
days. With the help of Howard Latimer,
responsible for inventing the process for
manufacturing the carbon filament, the light
bulb changed the world.
7. “Hi everybody! I’m Thomas Edison.
I invented a lot of things but this is my best
invention. It is the light bulb. Inside you will
see two rather heavy and stiff wires they are
made of iron and nickel. They are called the
leads. Stretched between them, in the
center of the bulb, is the filament, a smaller
wire made of tungsten, it is the working part
of the lamp.”
8. The first light bulbs
were installed in a
steamship and later
in a New York
factory.

10. So when you turn on the light
think of Thomas Edison.
11. When Edison died in October 1931,
entire cities were lit up by
electricity and as a tribute to this
genius, all of America dimmed
lights for one minute in his honour.
