	Reis
		Philipp Reis was born on the 7th of January, 1834 in Gelnhausen, Germany, in a Jewish family.
		Reis developed his invention; in the course of the time appeared 10 different forms of the transmitter (today microphone named) and 4 of the receiver.
		Reis was sickly, and impoverished, with neither the means nor the stamina to capitalize on the device.

	Johann Philipp Reis - Wikipedia, the free encyclopedia
		Johann Philipp Reis (January 7, 1834 – January 24, 1874), was born in Gelnhausen, Germany, as son to a poor Portuguese-Jewish baker.
		Philipp Reis had studied the organs of hearing, and the idea of an apparatus for transmitting sound by means of electricity had been floating in his mind for years.
		Philipp Reis was buried in the cemetery of Friedrichsdorff, and in 1878, after the introduction of the speaking telephone, the members of the Physical Society of Frankfort erected an obelisk of red sandstone bearing a medallion portrait over his grave.

		Johann Philipp Reis, the first inventor of an electric telephone, was born on January 7, 1834, at the little town of Gelnhausen, in Cassel, where his father was a master baker and petty farmer.
		But Reis does not seem to have realised the importance of not entirely breaking the circuit of the current; at all events, his metal spring is not in practice an effective provision against this, for it allows the metal contacts to jolt too far apart, and thus interrupt the current.

		Reis' devices are fragile and clumsy laboratory models, never put to public use, and are sold only to research labs or other experimenters.
		Reis was educated at Frankfurt am Main, became a merchant for a few years, and in 1858 began teaching in Friedrichsdorf.
		Reis believed that simple musical tones could be transmitted by the apparatus--which he called a telephone--and in fact such demonstrations with his instruments were common.

	Philipp Reis, a most eminent Telephone Pioneer
		As for Reis' telephone receiver, when operated by magnetostriction-- that is, on the principle on which it was designed and intended to operate -- it had inherent limitations that prevented its use for speech transmission, and was marginally acceptable for the mere transmission of tones.
		Philipp Reis essentially devised three different models of his Telephon, all of which were based on the same principle, namely the "make-and-break" of the current in the transmitter and the "magnetostriction" or "galvanic music" in the receiver.
		Philipp Reis clearly explained this mechanism in his lecture of October 26, 1861 at the Physical Society in Frankfurt-am-Main [10]: "At each closing of the circuit, the atoms of the iron wire inside the distant spiral are moved away from each other (Pouillet Müller, p.

	Invention of the telephone - Wikipedia, the free encyclopedia
		In 1860 Johann Philipp Reis produced a device which could transmit musical notes, and even a lisping sentence or two.
		The Reis transmitter was very difficult to operate, since the relative position of the needle and the contact were critical to the device's operation at all.
		But the articulation, though distinct, was feeble, and it remained for Edison (by inventing a transmitter that provided for independent power on the transmitting circuit) and David E. Hughes (by inventing the carbon microphone in 1878) to render the telephone the useful and widespread apparatus which we see it now.

		Philipp Reis resigned his membership in 1867; but the Free German Institute of Frankfurt, which elected him an honorary member, also slighted the instrument as a mere 'philosophical toy'.

		Denn Reis bat Kollegen, ihm Sätze mit sinnlosem Inhalt durchzusprechen, damit sich ausschließen ließ, dass er die Sätze erahnen konnte.
		Weil seine Erfindung auf keine große wissenschaftliche Resonanz stieß und er außerdem schwer erkrankte, verfolgte Reis die Vermarktung des Telefons nicht weiter, und den wahren Durchbruch in den USA erlebte er nur aus der Ferne.
		1874 starb Reis, nur 40jährig, in Friedrichsdorf an den Folgen einer Tuberkulose.

		The German science teacher Johann Philipp Reis (1834-1874) accomplished a remarkable feat in 1852, he invented a precursor to the telephone.
		In a homemade lab in a shed in his backyard, Reis assembled components that few people would associate with the construction of a telephone: a violin, a knitting needle, a large cork, a coil of wire, and a sausage.
		Reis then used a sausage skin stretched across a hollowed-out cork as a membrane for his crude microphone.
