The Birth of Electrical Engineering
THOMAS
A. EDISON (1847-1931) realized
in 1878 that the development of an electric
lighting device was of great importance.
In an interview, Edison stated:
"I
have an idea that I can make the electric
light available for all common uses, and
supply it at a trifling cost, compared
with that of gas. There is no difficulty
about dividing up the electric currents
and using small quantities at different
points. The trouble is in finding a candle
that will give a pleasant light, not too
intense, which can be turned on or off
as easily as gas."
-
Edison
eventually found the ideal filament
for his light bulb in the form of a
carbonized thread in 1879.
-
That
same year, Edison constructed the first
electric motor ever made for a 110 to
120 volt line at Menlo Park, New Jersey.
-
With
his early engineering insight, Edison
saw that a complete lighting system
was required.
-
By 1882, the system
had been conceived, designed, patented,
and tested at Menlo Park.
-
By 1882, his companies
built a system with 12,843 light bulbs
within a few blocks of Wall Street in
New York.
-
From
1880-1887, Edison underwent
his most strenuous years of invention
as he extended and improved greatly
upon his electric light, heat, and power
systems.
-
He took out over three hundred patents,
many of which were of extraordinary
and fundamental importance.
-
The most were those related to dividing
electric power and standardizing the
three-wire system and improving its
associated generation and feeder system.
-
The
great Electrical Exhibition of
1884 provided the site for
the first annual meeting of a new U.S.
professional society, the American Institute
of Electrical Engineers.
-
Edison, among others, called for a college
course of study in electrical engineering.
-
By
the mid-1880s such
course had begun at the Massachusetts
Institute of Technology and Cornell
University.
-
By 1890 electrical
engineering as a profession and an academic
discipline had begun with Edison as
a role and leader.
