Heinrich Rudolf Hertz (February 22, 1857 – January 1, 1894) was a German
physicist who clarified and expanded the electromagnetic theory of light that
had been put forth by Maxwell. He was the first to conclusively prove the
existence of electromagnetic waves by engineering instruments to transmit
and receive radio pulses usingexperimental procedures that ruled out all other
known wirelessphenomena.
