FIRST EDITION. As a student in Berlin, Heinrich Hertz noticed an announcement of a prize offered by the Berlin Philosophical Faculty for the solution of an experimental problem concerning electrical inertia. Helmholtz, who had proposed the problem and had great interest in its solution, provided Hertz with a room in his Physical Institute and directed him to literature on the problem. Hertz showed himself to be an extremely persistent and self-disciplined researcher; he spent hours pursing the problem. Hertz won the Philosophical Faculty prize in 1879, earning a medal, a first publication in Annalen der Physik in 1880, and Helmholtz' deepening respect. DSB, VI, p. 341.

SECOND EDITION IN ENGLISH of Untersuchungen uber die Ausbreitung der elektrischen Kraft. "Hertz was the first to demonstrate experimentally that electromagnetic waves radiate in space at the speed of light, just as Maxwell had predicted in his Treatise on Electricity and Magnetism. Hertz determined that electromagnetic waves were longer than light waves and showed that they were in complete correspondence with the waves of light and heat in the transverse nature of their vibration and their susceptibility to reflection, refraction, and polarization." [Hook & Norman]. "Experimental proof by Hertz of the Faraday-Maxwell hypothesis that electrical waves and be projected through space was begun in 1887, eight years after Maxwell's death. The two main requirements were (a) a method of producing the waves, supposing that they existed, and (b) a method of detecting them once they were produced. Hertz found the first problem easy to solve. He used the oscillatory discharge of a condenser. Detection was much more difficult, because there then existed no means of detecting currents alternating at the high speed of these waves. Hertz in fact used an effect as old as the discovery of electricity itself-the electric spark. By inducing the waves to produce an electric spark at a distance, with no apparent connexion between the oscillator and the spark gap, and by moving the sparking apparatus so that the length of the spark varied, he proved beyond question the passage of electric waves through space."
