Philipp Reis (Deutsch/ English/ Español (Sentanka) Übertragung von Sprache Mit den einfachsten Mitteln Über große Entfernung Versagt blieb ihm der Erfolg Viel zu früh kam sein Tod Transmission of voice By using the simplest means Over long distances Success was denied to him His death came far too early Transmisión de voz Utilizando medios más simples Por grandes distancias Se impedió el éxito Su muerte llegó demasiado pronto Johann Philipp Reis (1834, Gelnhausen, Hesse, Germany – 1874, Friedrichsdorf, Hesse, Germany) was a German-Jewish physicist and inventor. He is known as the inventor of the telephone and he developed an apparatus for 'transmission of sounds by means of electric cables'. He also invented a contact microphone and named his appliances 'Telephon'. This name was later internationally adopted. Another of his inventions were 'roller skates', the forerunner of modern inline skates. As a teacher he taught French, physics, mathematics and chemistry in Friedrichsdort, Taunus, Hesse. In his spare time he developed also a forerunner of the modern bycicle and experimented with solar power. To guarantee his pupils pretentious lessons, he constructed with simple means a reproduction of a human ear which stimulated later his invention of a telephone and a contact microphone between 1858 and 1863. He also developed three improved versions of the telephone. In 1861 he presented his prototype of a telephone to members of the Physical Association in Frankfurt (Main). His lecture was titled: Of the Transmission of Sounds over large Distance by means of Galvanic Electric Power'. A scientific report was printed in the annual of the association in 1860/61 with the title: ' Ueber die Telephonie durch den galvanischen Strom' (On Telephony by means of Galvanic Power). Reis' last developed prototype of a telephone already disposed a call signal. Unluckily he was not able to build more and improved telephones as he suffered early from tuberculosis. The inventor of the first functional telephone died at the age of 40 and was buried at the cemetary in Friedrichsdorf (Taunus). Alexander Graham Bell got to know Reis' telephone in 1862 in Edinburgh. Bell's father promised him and his brothers a prize money for further improvement of Reis' apparatus. In 1875 Bell experimented on a new telephone based on Reis' invention at the Smithonian Institute in Washington DC. The world wide known scientific magazine Nature reported on Reis' invention of the telephone as early as in the 1870ies.
