A number of historic sites and other marks commemorate Bell in North America and Europe, including the first telephone companies in the United States and Canada.
Among the major sites are:. These included the prestigious 'Volta Laboratory Association' , also known as the Volta Laboratory and as the 'Alexander Graham Bell Laboratory', and which eventually led to the Volta Bureau as a center for studies on deafness which is still in operation in Georgetown, Washington, D.
The Volta Laboratory became an experimental facility devoted to scientific discovery, and the very next year it improved Edison's phonograph by substituting wax for tinfoil as the recording medium and incising the recording rather than indenting it, key upgrades that Edison himself later adopted.
In partnership with Gardiner Greene Hubbard , Bell helped establish the publication Science during the early s.
In , Bell was elected as the second president of the National Geographic Society , serving until , and was primarily responsible for the extensive use of illustrations, including photography, in the magazine.
He was one of the founders of the American Institute of Electrical Engineers in and served as its president from to The First Day of Issue ceremony was held on October 28 in Boston, Massachusetts, the city where Bell spent considerable time on research and working with the deaf.
The Bell stamp became very popular and sold out in little time. The stamp became, and remains to this day, the most valuable one of the series.
The illustrations on the reverse of the note include Bell's face in profile, his signature, and objects from Bell's life and career: users of the telephone over the ages; an audio wave signal ; a diagram of a telephone receiver; geometric shapes from engineering structures; representations of sign language and the phonetic alphabet; the geese which helped him to understand flight; and the sheep which he studied to understand genetics.
That first flight was made by an airplane designed under Dr. Bell's tutelage, named the Silver Dart. In , Bell was also named as one of the 10 greatest Scottish scientists in history after having been listed in the National Library of Scotland 's 'Scottish Science Hall of Fame'.
Alexander Graham Bell, who could not complete the university program of his youth, received at least a dozen honorary degrees from academic institutions, including eight honorary LL.
Bell died of complications arising from diabetes on August 2, , at his private estate in Cape Breton, Nova Scotia, at age Bell, saying: .
My colleagues in the Government join with me in expressing to you our sense of the world's loss in the death of your distinguished husband.

On the behalf of the citizens of Canada, may I extend to you an expression of our combined gratitude and sympathy.
Bell's coffin was constructed of Beinn Bhreagh pine by his laboratory staff, lined with the same red silk fabric used in his tetrahedral kite experiments.
To help celebrate his life, his wife asked guests not to wear black the traditional funeral color while attending his service, during which soloist Jean MacDonald sang a verse of Robert Louis Stevenson 's "Requiem": .
Upon the conclusion of Bell's funeral, "every phone on the continent of North America was silenced in honor of the man who had given to mankind the means for direct communication at a distance".
Alexander Graham Bell was buried atop Beinn Bhreagh mountain, on his estate where he had resided increasingly for the last 35 years of his life, overlooking Bras d'Or Lake.

It received its historical designation from the Government of Canada on June 1, Mabel's exact age when she became deaf would later play a part in the debate on the effectiveness of manual versus oral education for deaf children , as children who are older at the onset of deafness retain greater vocalization skills and are thus more successful in oral education programs.
Some of the debate centred on whether Mabel had to relearn oral speech from scratch, or whether she never lost it. It was invented in Brantford at Tutela Heights in the summer of Others transmitted a sound or a click or a buzz but our boys [Bell and Watson] were the first to transmit speech one could understand.
Bell was so ecstatic that he wanted to jointly name his new invention and his new daughter Photophone Greek: " light—sound " ,   Bell wrote: "Only think!
Mabel's baby screamed inarticulately but mine spoke with distinct enunciation from the first. Bell quickly disassembled it and effected a repair, to the owner's amazement.

Marca leta sta Bell in Pollok obiskala slavnega znanstvenika Josepha Henryja. Toda Bell ni imel opreme in sposobnosti, da bi lahko zgradil model po svojih zamislih.
Istega jutra je Bellov odvetnik izpolnil patentno prijavo za telefon v lokalnem patentnem uradu. Ker pa je bil odvetnik stalna stranka urada, je Wilber privolil.
März in Edinburgh Schottland in einer Gelehrtenfamilie geboren. Er stellte seinen Sohn als Assistenten ein. Vater und Sohn untersuchten hier die Probleme der Sprache und beschäftigten sich mit tauben Kindern.
Im Jahre wanderte er mit seinen Eltern nach Nordamerika aus. Hier beschäftigte er sich ab auch mit akustischen Experimenten zur Aufzeichnung von Schallwellen.
His interest in sound technology was deep-rooted and personal, as both his wife and mother were deaf. Ultimately, the talented scientist held more than 18 patents for his inventions and work in communications.
Young Alexander was an intellectually curious child who studied piano and began inventing things at an early age.
Both of his brothers passed away from tuberculosis by the time Bell was in his early twenties. When he was just 12, the young Alexander invented a device with rotating paddles and nail brushes that could quickly remove husks from wheat grain to help improve a farming process.
At age 16, Bell began studying the mechanics of speech. In , Bell, along with his family, moved to Canada. The following year, he settled in the United States.
While in the U. In , he opened the School of Vocal Physiology and Mechanics of Speech in Boston, where deaf people were taught to speak.
While teaching, Bell met Mabel Hubbard, a deaf student. The couple married on July 11, They went on to have four children, including two sons who died as infants.
In , Bell started working on the harmonic telegraph — a device that allowed multiple messages to be transmitted over a wire at the same time.
While trying to perfect this technology, which was backed by a group of investors, Bell became preoccupied with finding a way to transmit human voice over wires.
By , Bell, with the help of his partner Thomas Watson, had come up with a simple receiver that could turn electricity into sound.
On March 7, , Bell was granted his telephone patent. Watson, come here. I want you.
