Historians label the period in Europe between the 14th and 16th centuries as the Renaissance a period of rebirth.
In the Renaissance Period the magnitude of scholarly and artistic activities was greatly enhanced in Europe. New knowledge was acquired which gave rise to new technologies, and the Industrial Age soon followed. The Industrial Age developed as mankind learned to harness the energy created from the burning of hydrocarbons, such as coal and petroleum. Mechanics emerged as a new science in universities.
Except for the magnetic compass, electric and magnetic energy remained a curiosity, having little practical application, until the invention of the battery by Alessandro Volta in 1800. This invention gave scientists a new tool with which to experiment, and soon the laws of electricity and magnetism were discovered.
In 1831 Faraday discovered that rotating a conductor in a magnetic field gave rise to an electric potential, and the electric generator and motor became a reality. However, the development of the electric power industry was really spurred by the invention of a practical incandescent electric light bulb in 1879 by Thomas Edison. The electrification of cities soon followed. Alternating current and the transformer allowed electric energy to be transported over large distances, and electrical engineering as a profession was born. The first professional society for electrical engineers was founded in 1884.
The discovery of the laws of electricity and magnetism in the 1800s also gave birth to two new information industries, the telegraph and telephone industries. However, the electric power industry remained a dominant force in the first half of the 20th century.
Two new non-electrical information industries were also created in the 1800s through advances in the chemical sciences. The photographic film process was perfected and the photographic industry was born soon to be followed by the motion picture industry.
