Alexander Graham Bell
| (March 3, 1847 – August 2, 1922) |

| Alexander Graham Bell was a Scottish scientist and
inventor. Today, Bell is still widely considered to be the foremost
inventor of the telephone, although this matter has become
controversial, with a number of people claiming that Antonio Meucci was
the real inventor (in June 2002, the United States House of
Representatives passed a symbolic bill officially recognizing Meucci for
his contributions to the invention of the telephone). Others advance
Elisha Gray, the founder of the Western Electric Manufacturing Company.
In addition to Bell's work in telecommunications technology, he was
responsible for important advances in aviation and hydrofoil technology. |
Born Alexander Bell in Edinburgh, Scotland, on March 3, 1847, he later
adopted the middle name 'Graham out of admiration for Alexander Graham, a family
friend. Many called Bell "the father of the Deaf." This title may be regarded as
somewhat ironic due to his belief in the practice of eugenics as well as his
strong audist stance. While both his mother and his wife were deaf, he hoped to
one day eliminate hereditary deafness.
His family was associated with the teaching of elocution: his grandfather in
London, his uncle in Dublin, and his father, Alexander Melville Bell, in
Edinburgh, were all professed elocutionists. The latter has published a variety
of works on the subject, several of which are well known, especially his
treatise on Visible Speech, which appeared in Edinburgh in 1868. In this he
explains his method of instructing deaf mutes, by means of their eyesight, how
to articulate words, and also how to read what other persons are saying by the
motions of their lips.
Alexander Graham Bell was educated at the Royal High School of Edinburgh, from
which he graduated at the age of 13. At the age of 16 he secured a position as a
pupil-teacher of elocution and music in Weston House Academy, at Elgin, Moray,
Scotland. The next year he spent at the University of Edinburgh. He was
graduated from University College London.
From 1867 to 1868, he was an instructor at Somersetshire College at Bath,
Somerset, England.
While still in Scotland he is said to have turned his attention to the science
of acoustics, with a view to ameliorate the deafness of his mother.
In 1870, at the age of 23, he emigrated with his family to Canada where they
settled at Brantford. Before he left Scotland, Bell had turned his attention to
telephony, and in Canada he continued an interest in communication machines. He
designed a piano which could transmit its music to a distance by means of
electricity. In 1873, he accompanied his father to Montreal, Canada, where he
was employed in teaching the system of visible speech. The elder Bell was
invited to introduce the system into a large day-school for mutes at Boston, but
he declined the post in favor of his son, who became Professor of Vocal
Physiology and Elocution at Boston University's School of Oratory.
Bell speaking into prototype model of the telephoneAt Boston University he
continued his research in the same field, and endeavored to produce a telephone
which would not only send musical notes, but articulate speech. With financing
from his American father-in-law, on March 7, 1876, the U.S. Patent Office
granted him Patent Number 174,465 covering "the method of, and apparatus for,
transmitting vocal or other sounds telegraphically … by causing electrical
undulations, similar in form to the vibrations of the air accompanying the said
vocal or other sound", the telephone.
However, it has been recognized (such as by the U.S. Congress in 2002) that
Meucci was the first to invent the telephone in 1871. Bell invented his own
telephone in 1875 after discovering that a receiver could also be a transmitter.
Some claim he went to the patent office and bribed the officials there to
destroy the records of Meucci's inventor-of-the-telephone status (Meucci was too
poor to secure a patent). In any case Bell then secured his own patent in 1876,
just hours before Elisha Gray visited the patent office for his own work on the
telephone. Meucci was understandably furious, and took Bell to court. However,
he was too poor to hire a legal team, and in declining health, he lost the court
case. To Bell's credit, he successfully fought off several lawsuits, refined the
telephone, and developed it into one of the most successful products. The Bell
Telephone Company was created in 1877, and by 1886 over 150,000 people in the
U.S. owned telephones and Bell became a millionaire.
After obtaining the patent for the telephone, Bell continued his many
experiments in communication, which culminated in the invention of the
photophone-transmission of sound on a beam of light — a precursor of today's
optical fiber systems. He also worked in medical research and invented
techniques for teaching speech to the deaf. The range of Bell's inventive genius
is represented only in part by the eighteen patents granted in his name alone
and the twelve he shared with his collaborators. These included fourteen for the
telephone and telegraph, four for the photophone, one for the phonograph, five
for aerial vehicles, four for hydroairplanes, and two for a selenium cell.
Bell had many ideas that were later realized in inventions. During his Volta
Laboratory period, Bell and his associates considered impressing a magnetic
field on a record, as a means of reproducing sound. Although the trio briefly
experimented with the concept, they were unable to develop a workable prototype.
They abandoned the idea, never realizing they had glimpsed a basic principle
which would one day find its application in the tape recorder, the hard disc and
floppy disc drive, and other magnetic media.
Bell's own home used a primitive form of air conditioning, in which fans blew
currents of air across great blocks of ice. He also anticipated modern concerns
with fuel shortages and industrial pollution. Methane gas, he reasoned, could be
produced from the waste of farms and factories. At his Canadian estate in Beinn
Bhreagh, Nova Scotia, he experimented with composting toilets and devices to
capture water from the atmosphere. In a magazine interview published shortly
before his death, he reflected on the possibility of using solar panels to heat
houses.
In 1882, he became a naturalized citizen of the United States. In 1888, he was
one of the founding members of the National Geographic Society and became its
second president. He was the recipient of many honors. The French Government
conferred on him the decoration of the Légion d'honneur (Legion of Honor), the
Académie française bestowed on him the Volta Prize of 50,000 francs, the Royal
Society of Arts in London awarded him the Albert Medal in 1902, and the
University of Würzburg, Bavaria, granted him a Ph.D. He was awarded the AIEE's
Edison Medal in 1914 for "For meritorious achievement in the invention of the
telephone."
Bell married Mabel Hubbard, who was one of his pupils at Boston University and
also a deaf-mute, on July 11, 1877. His invention of the telephone resulted from
his attempts to create a device that would allow him to communicate with his
wife and his deaf mother. He died at Beinn Bhreagh, located on Nova Scotia's
Cape Breton Island near the village of Baddeck, in 1922 was buried atop Beinn
Bhreagh mountain overlooking Bras d'Or Lake. He was survived by his wife and two
of their four children.
