description Thomas Edison Overview
Thomas Edison was a prolific inventor and engineer who established the first industrial research laboratory. His work on the incandescent light bulb, the phonograph, and the motion picture camera transformed modern life. While his direct current (DC) power system was eventually superseded by Tesla's AC, his contribution to the development of electrical distribution infrastructure was foundational. Edisons approach to engineeringcombining systematic experimentation with commercial applicationcreated the model for the modern corporate R&D department, influencing how technology is developed and brought to market today.

help Thomas Edison FAQ
How many patents did Thomas Edison hold?
Thomas Edison held 1,093 U.S. patents during his lifetime, including inventions for the light bulb, phonograph, and motion picture camera. He also held over 1,500 international patents, making him one of history's most prolific inventors.
What was the War of Currents?
The War of Currents (1880s-1890s) was a competitive dispute between Edison's Direct Current (DC) system and Tesla's Alternating Current (AC) system. Tesla's AC ultimately won due to its ability to transmit power over longer distances more efficiently.
What major inventions is Thomas Edison known for?
Edison is best known for the practical incandescent light bulb, phonograph, and motion picture camera. He also developed the first commercial electrical power distribution system and created the carbon microphone used in telephones.
When and where was Thomas Edison born?
Thomas Alva Edison was born on February 11, 1847, in Milan, Ohio. He died on October 18, 1931, in West Orange, New Jersey, at age 84.
