It all started with a German physicist named Heinrich Hertz who in 1884 proved that you could transmit and receive electric waves wirelessly. Hertz thought that the work he had done had no use whatsoever but little did he know that what he done is considered the fundamental building block of radio, and that is the reason why every frequency measurement is named after him (Short). In that same year a Serbian-American inventor named Nikola Tesla came to the U.S and sold patents to his inventions to a man named George Westinghouse. After that Tesla established his own lab which is where he built the tesla coil , an induction coil that is still used in radio today (Short). The next progression of radio focused on more than just the transmission of waves, the new focus was transmission of speech. The first to begin to add speech into the radio mix was Ernst Alexander, a Sweden born inventor who developed the first alternator to make speech transmission possible (Short).
