Why did Tesla invent radio's?

Answer 1

He didn't.

Many people 'could' take credit for the invention of the radio - and Tesla has his place in the list, but not for either discovering, inventing of it. If you want to know the inventor of radio, technically that might be a guy named Maxwell who theorized EM transmissions could be used to produce something like radio waves.

The first real work with Radio waves was done by Heinrich Rudolf Hertz between 1887 and 1890. He believe it or not didn't think his research was of any real use to people at the time. :)

Guglielmo Marconi would be the first to actually create a fully functioning system, and is generally considered the 'inventor of radio'. It's these patents that were reversed after the start of WWII that allowed Tesla's American Patents to give him credit for invention that confuse people. Marconi, being Italian - and not one of the Allied countries - and being nominated by Musolini as the Head of the Facsist Grand Council ... well, even though he died in 1937 - he lost his patents right after America went to war in 1943. Probably wasn't right that it happened but it did. As a result Tesla's patents were put in place and Tesla got revisioned in as a genius for inventing radio.

In reality - Tesla didn't think radio waves were real. Tesla thought that Maxwell, Lodge, and Hertz - pretty much everyone else -- was wrong in their findings that airborne electromagnetic waves (radio waves) existed. Tesla thought it was what he called "electrostatic thrusts", with the real signals being conducted by Earth currents and not through the air at all. So calling him the father of Radio is really misleading. He patented a model boat that used circuits he - frankly didn't understand - and demonstrated it to the press. For that, he got credit.

So Marconi was the first real long distance radio inventor. Reginald A. Fessenden will come along and introduce radio with audio (voices) in 1907 and then things really took off as we know them today.

It is notable that in the Blizzard of 1888 trains used a device created by Thomas Edison to transmit messages - it's beleived this is the first 'SOS' ever sent, but it used limited field induction - and although wireless communication, isn't generally considered a 'radio'. The earliest patent in wireless communication is from Alexander Gram Bell (inventor of the the Telephone) who created something called the Photophone in 1880 that used light waves instead of radio.
