Unable to locate him, Cassie had finally agreed to leave the twins with Mr. & Mrs. Hertz, their neighbors.
Mrs. Hertz was always talking about a nephew.
She stopped, remembering the photo on the wall in the Hertz cabin.
Were the twins with their father or still at the Hertz ranch?
HEINRICH RUDOLF HERTZ (1857-1894), German physicist, was born at Hamburg on the 22nd of February 1857.
The experimental proof, however, was still lacking, and though several experimenters had come very near its discovery, Hertz was the first who actually succeeded in supplying it, in 1887.
Hertz himself gave an admirable account of the significance of his discoveries in a lecture on the relations between light and electricity, delivered before the German Society for the Advancement of Natural Science and Medicine at Heidelberg in September 1889.
In 1889 Hertz was appointed to succeed R.
He employed as a detector of this wave a simple, nearly closed circuit of wire called a Hertz resonator, but it was subsequently discovered that the metallic microphone of D.

The youngest of the great poets born during the last twenty years of the 8th century was Henrik Hertz (q.v.; 1797-1870).
In his best pieces Hertz is the most modern and most cosmopolitan of the Danish writers of his time.
Electric Waves.-In the decade 1880-1890, the most important advance in electrical physics was, however, that which originated with the astonishing researches of Heinrich Rudolf Hertz (1857-1894).
Hertz then devised a wave detecting apparatus called a resonator.
These effects, as Hertz showed, indicated the establishment of stationary electric waves in space and the propagation of electric and magnetic force through space with a finite velocity.
Sir William Crookes took up in 1872 the study of electric discharge through The Work of Hertz (London, 1894).
Fitzgerald was the first to attempt to measure the length of electric waves; Helmholtz put the problem into the hands of his favourite pupil, Heinrich Hertz, and the latter finally gave an experimental demonstration of electromagnetic waves, the "Hertzian waves," on which wireless telegraphy depends, and the velocity of which is the same as that of light.
Beckmann obtained P4 molecules from the boiling-point of carbon bisulphide solutions, and Hertz arrived at the same conclusion from the lowering of the freezing-point in benzene solution; E.
There are modern German translations by Simrock (very close to the original) and Hertz (excellent notes).
