He urged the people who used his phone to say "hello" when answering . Bell understood that if sound could be transmitted as an electrical current, it would be possible for a receiver to interpret those vibrations. [93], 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. In 1984, the former AT&T agreed to divest its local telephone operations but retain its long distance, R&D and manufacturing arms. Articles from Britannica Encyclopedias for elementary and high school students. [52][N 8] 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. At Boston University, Bell was "swept up" by the excitement engendered by the many scientists and inventors residing in the city. Wow, that's pretty neat. The New York Times reported: On October 9, 1876, Alexander Graham Bell and Thomas A. Watson talked by telephone to each other over a two-mile wire stretched between Cambridge and Boston. [25] His school record was undistinguished, marked by absenteeism and lacklustre grades. In Bells luggage was his new communication device, the telephone.

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.D.s (Doctorate of Laws), two Ph.D.s, a D.Sc., and an M.D. In 1873 British scientist Willoughby Smith discovered that the element selenium, a semiconductor, varied its electrical resistance with the intensity of incident light. George's father, Thomas Sanders, a wealthy businessman, offered Bell a place to stay in nearby Salem with Georgie's grandmother, complete with a room to "experiment". In personal correspondence to Bell, both Gray and Dolbear had acknowledged his prior work, which considerably weakened their later claims.

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. During this period, he alternated between Boston and Brantford, spending summers in his Canadian home. In one memorable incident, the newly arrived Bells were walking down one of Baddeck's central streets when Bell peered into a storefront window and saw a frustrated shopkeeper fiddling with his problematic telephone.
