HERTZ, HEINRICH (1857-1894).

German physicist; pupil of the German scholar Helmholtz. He became world-famous through his experiments on the propagation of electrical waves. These experiments proved the electromagnetic theory of light that had been developed in 1865 by the British physicist Maxwell. Hertz’s work paved the way for the era of electronics, culminating in the discovery of wireless telegraphy, radio, and television.
