In the middle of the nineteenth
century there was an idea to transfer
at distance information by means of
electricity. Who the first invented
phone? For the first time, the teacher
managed to carry out this idea
physics to Philip Reys on the twenty
sixth of October, 1861 in Germany. Its
device had the original microphone,
the power supply representing the
galvanic battery, and the loudspeaker.
This device was also called scientific
Telephon.

The device underwent numerous
improvements. So, in the device
Bella there was no call, and the
tube served both for transfer of
the human speech, and for its
reception. In 1877 the famous
inventor Vaden used the special
cable key closing a call chain for
the subscriber's call. Subsequently
it was replaced with the button. In
the same time the German plant
"Siemens and Galsk" located in St.
Petersburg began production the
telephone sets having two tubes –
for reception and a speech
transmission.
I consider that phone this necessary invention. By
means of phone, the mankind came to the new level of
communication. We can communicate at distance with
the friends and relatives and to write each other letters
without using paper and the handle
In the mid-19th century, the first phone was invented by a German teacher named Philip Reys in 1861, followed by the famous Scottish scientist Alexander Graham Bell who patented his device.
