A stolen invention by Milena Madriz

There are varying disputed claims about who invented radio which in the beginning was called wireless telegraphy. The key invention for the beginning of "wireless transmission of data using the entire frequency spectrum", has been attributed to various men. Marconi equipped ships with lifesaving wireless communications and established the first transatlantic radio service. Tesla developed means to reliably produce radio frequency electrical currents, publicly demonstrated the principles of radio, and transmitted long distance signals; but the patent of radio was awarded by Marconi.
The true is that who really invented it was Nikola Tesla,but due to his eccentric personality and his seemingly unbelievable and sometimes bizarre claims about possible scientific and technological developments, Tesla was ultimately ostracized and regarded as a mad scientist.
He initially used sensitive electromagetic receivers,that were unlike the less responsive coherers later used by Marconi and other early experimenters.
After 1892, Tesla delivered a widely reported presentation before the Institution of Electrical Engineers of London in which he suggested that messages could be transmitted without wires. Later, a variety of Tesla's radio frequency systems were demonstrated during another widely known lecture, presented to meetings of the National Electric Light Association.
Tesla died impoverished and ill, he wasn't recognised by his inventions and the main reason of this was his mental problems.
