Thomas Alva Edison
February 11, 1847 – October 18, 1931
Despite the controversial opinions of Thomas
Edison is one of the main inventors of the 19th
and 20th centuries. He developed many
devices that greatly influenced life around the
world, including the motion picture camera
and the long-lasting, practical electric light
bulb. This presentation is about it.
Early life
In school, the young Edison's mind often
wandered, and his teacher, the Reverend Engle,
was overheard calling him “addled”. This ended
Edison's three months teaching in school.
*Edison said later, "My mother was the making of me. She
was so true, so sure of me; and I felt I had something
to live for, someone I must not disappoint."
Hearing problems
Edison developed hearing problems at an early age.
The cause of his deafness has been attributed to a bout of
scarlet fever during childhood and recurring untreated
middle-ear infections.
Hearing problems
Around the middle of his career, Edison
attributed the hearing impairment to being struck
on the ears by a train conductor when his
chemical laboratory a boxcar caught fire and he
was thrown off a train, along with his apparatus
and chemicals. In his later years, he changed story
to say the injury occurred when the conductor, in
helping him onto a moving train, lifted him by the
Beginning his career
Edison obtained the exclusive right to
sell newspapers on the road, and, with
the aid of four assistants, he set in type
and printed the Grand Trunk Herald,
which he sold with his other papers. So
Edison started his business and opened
a talent of businessman. These talents
helped him to create 14 companies,
including General Electric, which is still
one of the largest publicly traded
companies in the world.
In 1889, Drexel, Morgan & Co., a company
founded by J.P. Morgan and Anthony J. Drexel,
financed Edison's research and helped merge those
companies under one corporation to form Edison
General Electric Company which was incorporated
in New York on April 24, 1889.
Electric light
After many experiments, first with carbon filaments and then with
platinum and other metals, Edison continued to improve this design and
by November 4, 1879, filed for U.S. patent 223,898 for an electric lamp
using "a carbon filament or strip coiled and connected to platina contact
wires". This was the first commercially practical incandescent light.
Edison is credited with designing and
producing the first commercially available
fluoroscope, a machine that uses X-rays to take
The fundamental design of Edison's
fluoroscope is still in use today, although
Edison himself abandoned the project after
nearly losing his own eyesight and seriously
injuring his assistant.
War of currents
As Edison was expanding his direct
current (DC) power delivery system he
began receiving stiff competition from
companies installing alternating current
(AC) systems. Edison expressed views that
AC was unworkable and the high
voltages used were dangerous.
Kinetoscope - optical device to
display moving pictures, invented by
Edison in 1888. Watching a movie could
an individual through a special
eyepiece - it was a personal cinema.
The cinema of the Lumiere brothers used
the same type of film and similar long
drawn out mechanism.
Edison began the "war of patents",
justifying its priority on film with perforation
and requiring for its use of deductions.
When Georges Méliès sent US several
copies of his film a trip to the moon, the
Edison company filmed a movie and
started to sell tens of copies. . "A trip to the
moon" helped to open the first permanent
theater in Los Angeles, one of the suburbs
which was called Hollywood.
Edison died of complications of diabetes
on October 18, 1931, in his home,
"Glenmont" in Llewellyn Park in West
Orange, New Jersey.
Despite the controversial opinion about this man Thomas
Edison was one of the most important persons of the 20th the 19th century. This man was an important scientist and
inventor who contributed several inventions that are still
used in our world today.
For me his greatest invention is the electric lightbulb.
Without it, our world today would be different.
His invention was created 20th century.
