Alexander Graham Bell

Alexander Graham Bell (March 3, 1847 – August 2, 1922) was a Scottish-born American inventor, scientist, and engineer who is credited with inventing and patenting the first practical telephone.

In 1876, Alexander Graham Bell was the first to be granted a United States patent for a device that produced clearly intelligible replication of the human voice.

Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils, and aeronautics.

Alexander Graham Bell considered the invention of the hydroplane a very significant achievement, and after reading the article began to sketch concepts of what is now called a hydrofoil boat.

Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils, and aeronautics.

In 1880, Alexander Graham Bell and his assistant Charles Sumner Tainter created the photophone, at Bell's newly established Volta Laboratory in Washington, DC.

His father was Professor Alexander Melville Bell, a phonetician, and his mother was Eliza Grace (née Symonds).

Additionally he was also the creator of Visible Speech which was used to help the deaf learn to talk, and was the father of Alexander Graham Bell.

Although Bell was not one of the 33 founders of the National Geographic Society, he had a strong influence on the magazine while serving as the second president from January 7, 1898, until 1903.

Gardiner Greene Hubbard became its first president and his son-in-law, Alexander Graham Bell, succeeded him in 1897.

The Bell family soon purchased a farm of 10.5 acre at Tutelo Heights (now called Tutela Heights), near Brantford, Ontario.

The city's famous resident, Alexander Graham Bell, invented the device at his father's homestead, Melville House, now the Bell Homestead.

In 1870, 23-year-old Bell travelled with his parents and his brother's widow, Caroline Margaret Ottaway, to Paris, Ontario, to stay with the Reverend Thomas Henderson, a family friend.

While the telephone was invented at Brantford, Ontario, in 1874, Alexander Graham Bell reminded people in the area about a Paris connection.

Deciding to give up his lucrative private Boston practice, Bell retained only two students, six-year-old "Georgie" Sanders, deaf from birth, and 15-year-old Mabel Hubbard.

As the wife of Alexander Graham Bell, inventor of the first practical telephone, she took the married name Mabel Bell.

His father helped him set up his private practice by contacting Gardiner Greene Hubbard, the president of the Clarke School for the Deaf for a recommendation.

One of his daughters, Mabel Gardiner Hubbard, also became the wife of Alexander Graham Bell.

In 1872, Bell became professor of Vocal Physiology and Elocution at the Boston University School of Oratory.

In 1876, BU professor Alexander Graham Bell invented the telephone in a BU lab.

He continued his interest in the study of the human voice and when he discovered the Six Nations Reserve across the river at Onondaga, he learned the Mohawk language and translated its unwritten vocabulary into Visible Speech symbols.

The Scottish-Canadian-American scientist Alexander Graham Bell, one of the inventors of the telephone, was greatly interested in the human voice: when he came across the Six Nations Reserve across the river at Onondaga, he learned the Mohawk language and translated its then unwritten vocabulary into Visible Speech symbols for the first time.

However, a chance meeting in 1874 between Bell and Thomas A. Watson, an experienced electrical designer and mechanic at the electrical machine shop of Charles Williams, changed all that.

Thomas Augustus Watson (January 18, 1854 – December 13, 1934) was an assistant to Alexander Graham Bell, notably in the invention of the telephone in 1876.

While he was working as a private tutor, one of his pupils was Helen Keller, who came to him as a young child unable to see, hear, or speak.

Chisholm referred the Kellers to Alexander Graham Bell, who was working with deaf children at the time.

Antonio Meucci sent a telephone model and technical details to the Western Union telegraph company but failed to win a meeting with executives.

In 1876, Alexander Graham Bell was granted a patent for the electromagnetic transmission of vocal sound by undulatory electric current.

Orton had contracted with inventors Thomas Edison and Elisha Gray to find a way to send multiple telegraph messages on each telegraph line to avoid the great cost of constructing new lines.

Some recent authors have argued that Gray should be considered the true inventor of the telephone because Alexander Graham Bell allegedly stole the idea of the liquid transmitter from him, although Gray had been using [[Elisha Gray and Alexander Bell telephone controversy#Use of liquid transmitters for telephone experiments.2C 1873-1876|liquid transmitters in his telephone experiments for more than two years previously]].

A short time later, his demonstration of an early telephone prototype at the 1876 Centennial Exposition in Philadelphia brought the telephone to international attention.

The Bell Telephone Company, a common law joint stock company, was organized in Boston, Massachusetts on July 9, 1877, by Alexander Graham Bell's father-in-law Gardiner Greene Hubbard, who also helped organize a sister company — the New England Telephone and Telegraph Company.

Bell's father taught him and his brothers not only to write Visible Speech but to identify any symbol and its accompanying sound.

Melville's works on Visible Speech became highly notable, and were described by Édouard Séguin as being "...a greater invention than the telephone by his son, Alexander Graham Bell".

Patent matters would be handled by Hubbard's patent attorney, Anthony Pollok.

Anthony Pollok (1829 – July 4, 1898) was an American patent attorney who, with Marcellus Bailey, helped prepare Alexander Graham Bell's patents for the telephone and related inventions.

Orton had contracted with inventors Thomas Edison and Elisha Gray to find a way to send multiple telegraph messages on each telegraph line to avoid the great cost of constructing new lines.

Although Edison obtained a patent for the phonograph in 1878, he did little to develop it until Alexander Graham Bell, Chichester Bell, and Charles Tainter produced a phonograph-like device in the 1880s that used wax-coated cardboard cylinders.

He was subsequently asked to repeat the programme at the American Asylum for Deaf-mutes in Hartford, Connecticut, and the Clarke School for the Deaf in Northampton, Massachusetts.

Alexander Graham Bell and Grace Coolidge have served as heads of school.

In January 1915, Bell made the first ceremonial transcontinental telephone call.

The first telephone call was made on March 10, 1876 by Alexander Graham Bell.

He also co-founded the American Telephone and Telegraph Company (AT&T) in 1885.

AT&T started with Bell Patent Association, a legal entity established in 1874 to protect the patent rights of Alexander Graham Bell after he invented the telephone system.

By 1889, a large house, christened The Lodge was completed and two years later, a larger complex of buildings, including a new laboratory, were begun that the Bells would name Beinn Bhreagh (Gaelic: beautiful mountain) after Bell's ancestral Scottish highlands.

Beinn Bhreagh is the name of the former estate of Alexander Graham Bell, in Victoria County, Nova Scotia.

The patent examiner, Zenas Fisk Wilber, later stated in an affidavit that he was an alcoholic who was much in debt to Bell's lawyer, Marcellus Bailey, with whom he had served in the Civil War.

Marcellus Bailey (1840 – January 16, 1921) was an American patent attorney who, with Anthony Pollok, helped prepare Alexander Graham Bell's patents for the telephone and related inventions.

Bell also built the Bell Boatyard on the estate, employing up to 40 people building experimental craft as well as wartime lifeboats and workboats for the Royal Canadian Navy and pleasure craft for the Bell family.

The Bell Boatyard was a boatbuilding facility which operated as part of Alexander Graham Bell's laboratories in Baddeck, Nova Scotia from 1885 to 1928.
