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

In 1876, Scottish emigrant 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.

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.

After preparing a constitution and a plan of organization, the National Geographic Society was incorporated two weeks later on January 27. Gardiner Greene Hubbard became its first president and his son-in-law, Alexander Graham Bell, succeeded him in 1897.

He also 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.

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.

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

The following year, he attended the University of Edinburgh; joining his older brother Melville who had enrolled there the previous year.

Alumni of the university include some of the major figures of modern history, including physicist James Clerk Maxwell, naturalist Charles Darwin, philosopher David Hume, mathematician Thomas Bayes, surgeon Joseph Lister, signatories of the American declaration of independence James Wilson, John Witherspoon and Benjamin Rush, inventor Alexander Graham Bell, first president of Tanzania Julius Nyerere, and a host of famous authors such as Sir Arthur Conan Doyle, Robert Louis Stevenson, J.M. Barrie and Sir Walter Scott.

After a brief stay with the Hendersons, the Bell family 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 1893, Keller performed the sod-breaking ceremony for the construction of Bell's new Volta Bureau, dedicated to "the increase and diffusion of knowledge relating to the deaf".

The Volta Laboratory (also known as the "Alexander Graham Bell Laboratory", the "Bell Carriage House" and the "Bell Laboratory") and the Volta Bureau were created in Georgetown, Washington, D.C. by Alexander Graham Bell.

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.

After landing at Quebec City, the Bells transferred to another steamer to Montreal and then boarded a train 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, an eminent scientist and the inventor of the first practical telephone, she took the married name Mabel Bell.

In the following year, 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.

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

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.

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.

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]].

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.

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.

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 Dr. Alexander Graham Bell, in Victoria County, Nova Scotia.

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 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.

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.

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.

These included 14 for the telephone and telegraph, four for the photophone, one for the phonograph, five for aerial vehicles, four for "hydroairplanes", and two for selenium cells.

It was invented jointly by Alexander Graham Bell and his assistant Charles Sumner Tainter on February 19, 1880, at Bell's laboratory at 1325 L Street in Washington, D.C. Both were later to become full associates in the Volta Laboratory Association, created and financed by Bell.

These included 14 for the telephone and telegraph, four for the photophone, one for the phonograph, five for aerial vehicles, four for "hydroairplanes", and two for selenium cells.

Alexander Graham Bell's Volta Laboratory made several improvements in the 1880s and introduced the graphophone, including the use of wax-coated cardboard cylinders and a cutting stylus that moved from side to side in a zigzag groove around the record.

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.
