Hertz's experiments with electromagnetic waves led to the development of the wireless telegraph and radio.
Even as a young kid Hertz showed a great interest in physics.
Born in Hamburg, he went on to study the subject he loved and attained a PhD on it by the age of 22.
During his later days as a professor, Hertz experimented with electrical circuits and demonstrated electromagnetic induction to his students. During his experiments he noticed the emergence of 'side-sparks' in another loop. Three years later, he was able to demonstrate that the .
Hertz's finding -- that electromagnetic emissions associated with 'side sparks' behaved like waves during an experiment -- effectively clarified and expanded the electromagnetic theory of light, and from it they were able to confirm that electromagnetic waves could be transmitted and received.
Hertz's name came to be used to measure radio and electrical frequencies -- as in hertz (Hz), kilohertz (kHz) and megahertz (MHz).
He died in 1894 after contracting Wegener's granulomatosis, a rare disorder in which blood vessels become inflamed.
