Heirich Rudolf Hertz

Featured Accomplishment: Experimental demonstration of the reality of electromagnetic waves.
German physicist
Born: February 22, 1857, Hamburg, German Confederation
Died: January 1, 1894 (aged 36) Bonn, Germany
  Heinrich Rudolf Hertz was a German physicist who first conclusively proved the existence of the electromagnetic waves as predicted by James Clerk Maxwell’s equations of electromagnetism. At a time before the electron was discovered, Hertz proved that the carrier of electric current must have negligible mass. Hertz discovered the photo electric effect.

  Hertz was the first to demonstrate that cathode rays could penetrate very thin metal foil (such as aluminium). This led to the invention of the cathode ray tube by one of Hertz’s students. Hertz also published seminal papers on contact mechanics. Contact mechanics is the study of the deformation of solids that touch each other at one or more points. The unit of frequency, the Hertz, is named in his honour.
