itted to two famous scientists for
arbitration. They reported that the telegraph was the result of
their joint labors. To Wheatstone belongs the credit for devising
the apparatus; to Cooke for introducing it and placing it before the
public in working form. Here we see the combination of the man of
science and the man of business, each contributing needed talents for
the establishment of a great invention on a working basis.

Wheatstone's researches in the field of electricity were constant.
In 1840 he devised a magnetic clock and proposed a plan by which many
clocks, located at different points, could be set at regular intervals
with the aid of electricity. Such a system was the forerunner of
the electrically wound and regulated clocks with which we are now so
familiar. He also devised a method for measuring the resistance which
wires offer to the passage of an electric current. This is known
as Wheatstone's bridge and is still in use in every electrical and
physical laboratory. He also invented a sound telegraph by which
signals were transmitted by the strokes of a bell operated by the
current at the receiving end of the circuit.

The invention of Wheatstone's which proved to be of greatest lasting
importance in connection with the telegraph was the automatic
transmitter. By this system the message is first punched in a strip of
paper which, when passed through the sending instrument, transmits the
message. By this means he was able to send messages at the rate of one
hundred words a minute. This automatic transmitter is much used for
press telegrams where duplicate messages are to be sent to various
points.

The automatic transmitter brought knighthood to its inventor,
Wheatstone receiving this honor in 1868. Wheatstone took an active
part in the development of the telegraph and the submarine cable up to
the time of his death in 1875.

Wheatstone's telegraph would have served the purposes of humanity
and probably have been universally adopted, had not a better one been
invented almost before it was established. And it is because Morse,
taking up the work where others had left off, was able to invent an
instrument which so fully satisfied the requirements of man for so
long a period that he is known to all of us as the inventor of the
telegraph. And yet, without belittling the part played by Morse,
we must recognize the important work accomplished by Sir Charles
Wheatstone.
