Heinrich Hertz nsIn existographies, Heinrich Hertz (1857-1894) (IQ:180|#173) [RGM:151|1,500+] (Murray 4000:N/A) (Gottlieb 1000:453) (Kanowitz 50:24) (SIG:11) (GPE:36) was a German physicist, noted for []

Electromagnetic theory
In 1879, Hermann Helmholtz suggested to Hertz that he do his doctoral dissertation on testing and proving Maxwell’s electromagnetic theory (1865).

In Nov 1886, Hertz, while experimenting with a pair of Reiss spirals, noticed that discharging a Leyden jar into one of these coils would produce a spark in the other coil, and their in saw the way to experimentally prove Maxwell’s theory;

Hertz experiment 2

that month, Hertz, in short, became the first person to transmit and receive controlled radio waves.

Thermodynamics
In radiation thermodynamics, Hertz is noted for having given a mechanical derivation of the second law of thermodynamics; a derivation, however, that was considered invalid by German mathematician Ernst Zermelo. [1]
