Notes

Alexander Graham Bell (3 Mairch, 1847 – 2 August, 1922)[3] wis a Scots-born scientist, inventor, wha bided in Canadae, an efter in the Unitit States, wis foonder o the Bell Canada, and the American Telephone and Telegraph Company (AT&T)[4] an wis kent as the 'faither o the telephone'.[5] As weel as his wark in telecommunications technology, he wis responsible for important advances in aviation an hydrofoil technology.

Baith his mither and sister war baith profoondly deif, and male members o his faimily workit oan speech and elocution. This mey hae influenced Bell's ain research,[6] that led tae him gettin the first U.S. patent, oan & March 1876, fur the telephone.[7] Tho he refulsed tae hae a telephone in his ain study fur it wad interupt his ither research wark [7]

He wis forby interested in heredity and his wark on this wis cawed "the soundest, and most useful study of human heredity proposed in nineteenth-century America... Bell's most notable contribution to basic science, as distinct from invention."[6]

He becam the second preses (1898 -1903) o the National Geographic Society.[8]

Early life and faimily

Born Alexander Bell in Edinburgh on 3 March 1847, his faither wis Alexander Melville Bell, a phoneticist wha developed sign language and his mither wis Eliza Grace Bell (née Symonds),[9] the faimily bided in Charlotte Street. He askit his faither tae gie him a middle name like his twa brithers, and sae wis named aifter a lodger wha his faither wis treatin, Alexander Graham, sae frae the age o elelven, he wis kent as Alexander Graham Bell.[10] His twa brithers Melville James Bell (1845–1870) and Edward Charles Bell (1848–1867), baith de'ed o tuberculosis.[11] His mither (frae Bell wis twelve) and sister were baith deif, and he becam interessit in hou tae communicate wi thaim, and in acoustics.[12] Bell wis musical and inventive as a child, and his parents encouraged him. His faither taucht him Visible Speech method, and Bell could interpet mony leids, wi'oot kennin the pronounciation sik as Laitin, Scots Gaelic and Sanskrit.[13] He then bided wi his granfaither in Lunnon fir ane year afore he gaed tae be a pupil-teacher o elocution and music but studied Laitin and Greek at Weston House Academy, Elgin, Moray.

Then he went tae the Varsity o Edinburgh, and also wis back at Elgin, and tocht in Bath, Somerset. And whiles he wis ill hissel, his younger brither Edward never rekivert and de'ed o tuberculosis (1867). And his elder brither, Melville in 1870. His faither hid years afore convalesced in Newfoondland, and as Bell wis also ill, tho he wis tae study at the Varsity o Lunnin, and had whiles tocht deif childer in Lunnon wi his faither, the faimily went tae bide in Canadae.[6]

Research and teachin

Bells' faither encouraged him, and his brither Melville wha workit wi him, oan experiments on soond and acoustics. Yin involved makin a model o the thrapple (larynx) and skult, and usin bellows tae mak it spikk,[13] anither involved a dug, a Skye Tarrie, Trouve by making it mak 'human' soounds by pressin oan its thrapple and movin its lips wi his haunds.[14]

Baith in Canadae, and then in Boston, Bell workit wi the deif wi his faither, as a teacher in his ain shuil. Yin o Bell's private puplis wis Hellen Keller, baith blin and deif and nae able tae spikk. She was tocht by Bell using his faither's method and wis askit tae cut the sod fur the foondin o Bell's own institute, Volta Bureau, for "the increase and diffusion of knowledge relating to the deaf".[15]

In 1872, he becam professor o Vocal Physiology and Elocution at the Boston Varsity Schull o Oratory. He tocht private pupils and continued tae experiment wi sound and music transmission. But he becam unweel forby.[14]

The telephone

Bell experimented wi soond transmission in various weys, includin a phonoautograph, and uisin electric currents tae trasmit the soonds.[16] At this time, 1870s, the telegraph wis growin across Americae an Canadae. Bell told twa walthie investors aboot his invention tae send multiple tones on a telegraph an this startit the investment ahint his invention ( and the necessary protection by patent), the telephone in 1875.[17] Another model by Elisha Gray wis forby applying fur a patent, and challenged Bell's application.

But his patent 174,465, was issued to Bell on March 7, 1876, by the U.S. Patent Office. This covered "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."[7] Three days later, 10 March 1876, Bell transmitted soond by varying electrical currents. But he developed a better model wi electomagnetic methods. He continued to test his approach and eventually in August 1876, sent a soond transmission, ane wey, four miles frae his haim, and then eight miles tae Paris, Ontario.[18] His next step wis twa-wey conversation and this cam aboot oan 9 October 1876, frae Cambridge, Maryland tae Boston.[19]

The followin year, the Bell Telephone Company wis creatit an with an decade aboot 150,000 fowk in the Unitit States owned a telephone. Within twa years, Bell's demonstration o the telephone becam nationwide then international in a call wi Queen Victoria oan the Isle o Wight tae Soothhampton an Lunnon and an offer o a set o telephones fir hir uise.[20]

Death

Bell de'ed o complications frae diabetes oan 2 August 1922.[21][6]
