| | Experimenter
English, was committed by a merchant of musical instruments until the
publication in 1823, curious experiences on the sound. It also
interested resonance column of air, the transmission of sound in solid
conductors and linear (1831) and built a machine speaker.
In 1834 he was appointed professor at King's College, London, but
leaves the chair
after a few years. In 1834 publish its experiences in the electrical
field. In 1837 he exhibited in the Quarterly Journal of Science
the experiences on sound and the description of an ingenious
device, the noise calendoscopio becoming the first source for the
optical sound. Year following the stereoscope invented, perfected by
Brewster. In February 1838 in London he filed the
patent of
telegraph, after dedicating his improvement and possible applications.
Finally in 1869 invented a device used to measure with precision the
resistance known as "BRIDGE OF WHEATSTONE".

Charles
Wheatstone was born above his family's shop at 52/54 West gate Street
and at the age of 14 was apprenticed to his uncle, a musical instrument
maker in London.
Charles became fascinated with the physics of both sound and
electricity, and having invented the concertina in 1829 went on to
perfect a stereoscope for viewing photographs ( which became invaluable
for 20th Century aerial reconnaissance ) and devices for measuring the
speed of electricity and light.
In 1834 he became
Professor of experimental physics at Kings College
London, and in 1837 - along with William Cooke - developed the electric
telegraph. This was first used to control trains between Euston station
and Chalk Farm in London. He was later knighted by Queen Victoria for
his work on the first transatlantic telegraph cable.
He is also remembered for the Wheatstone bridge - used to measure
electrical resistance - and the " Magic Harp " which inspired Alexander
Graham Bell to invent the telephone. |
