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.
