Who Invented Radio?

In sum, Radio was not invented by a single person, instead it was the end results of a culmination of scientists' research; each pioneered diversify areas of electromagnetic radiation and radio waves during the late 1800s. Among these well known researchers are Heinrich Rudolf Hertz, James Clerk Maxwell, David E. Hughes, Thomas Edison, and Nikola Tesla.

The history of radio innovation begins in the 1800s, where the first true wireless experiments were carried out with James Maxwell's theories, integrated into Michael Faraday experiments to prove the theory of electromagnetism.

In the 1860's, electromagnetism was first discovered by James Clerk Maxwell. Electromagnetic waves could be manipulated into a medium of transmission of sound. In 1870s, David Edward Hughes created the first method of induction transmission which then allowed Morse code to be received and transmitted - now known as the radio waves.

In 1887, Heinrich Hertz refined his system that allowed him to experiment with sending wireless signals to a wireless receiver while in 1933 Hertz was honored when the unit of measure of radio and electrical frequencies was named in his honor as part of the new International Metric System.

The 1890s denote a big decade for the invention of radio. Nikola Tesla, renowned opponent to Edison, was granted several patents for major advancements in radio technology, including generators to produce radio signals and radio frequency power supplies.

The 1920s truly were the birth years of modern radio innovation. The development of stable mass produced vacuum valves made it possible for homes to own a radio. Each radio can be fitted into a cabinet that would take pride of place in the family living room which also signifies the wealth of the family as not everyone can own one.

Last but not least, Edwin Armstrong, a radio pioneer with the Navy during WWI continued to develop his experiments by reinventing radio broadcasting, which resulted in frequency modulation (FM) in 1933. Then, scientists from Bell Labs invented the transistor in 1947; a technology that transformed modern electronics.
