When was Radio invented?

There were many people involved in the making or invention of the radio. It is known today that not a single person was behind it. The invention of the radio began with “wireless telegraphy.” Also, the invention of radio somehow developed the invention of the telegraph and the telephone. All these three technologies relatively happened at the same time and these are closely related as well.  

The electronic device which is used to listen to some content is a ‘Radio.' In any case, everything related to the radio started with the invention of ‘radio waves.' These ways are also known as electromagnetic. The radio or electromagnetic waves tend to transmit speech, music, pictures or any data that is invisible through the air.

Not only radio, but many devices are there which works with the help of radio waves, for example, cordless phones, microwave, radio, television broadcast and much more.

Origin of the Invention

It was in 1860’s when James Clerk Maxwell a Scottish physicist predicted that the waves, named as electromagnetic. A German physicist Heinrich Rudolph Hertz took the initiative in 1886 to demonstrate the swift movement of electric current that can be projected into space that can be formed into radio waves. This is a similar process as light and heat.

In the year 1866, an American dentist named Mahlon Loomis further demonstrated the process of “wireless telegraphy.” Loomis connected a meter to two kites, so with the movement of one, the other also moved. This is marked to be the first documented instance of wireless aerial communication.

Some of the noteworthy people to remember when the invention of Radio is talked about are:

#1. Guglielmo Marconi

An Italian inventor, Guglielmo Marconi proved the accessibility of radio communication. He first sent the radio signal in Italy in the year 1895 and also received the signal. By 1899, he demonstrated the very first activity which was with wireless signals across the English channel. After two years he received a letter ‘S,' that was telegraphed to Newfoundland from England. This is the very first victorious attempt in 1902 of transatlantic radio telegraph message.

#2. Nikola Tesla

After the work of Marconi, two of the contemporaries, Nathan Shuffle field, and Nikola Tesla took the initiative to patents for the wireless radio transmitters. The first person who is credited for authoritatively approved radio technology. In favor of Tesla in 1943, the Supreme Court overturned the patent of Marconi.
