Alexander Graham Bell (1847-1922) was a Scottish inventor and scientist best known for creating the first practical telephone. Wikipedia says,


"[Bell's] research on hearing and speech further led him to experiment with hearing devices which eventually culminated in Bell being award the first U.S. patent for the telephone in 1876... Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils and aeronautics." (Wikipedia: Alexander Graham Bell, 8.21.21 UTC 00:26)


The rest of this quote is some quotes from Bell.




"Watson... if I can get a mechanism which will make a current of electricity vary in its intensity, as the air varies in density when a sound is passing through it, I can telegraph any sound, even the sound of speech." (


"Grand telegraphic discovery today... Transmitted vocal sounds for the first time... With some further modification I hope we may be enabled to distinguish... the 'timbre' of the sound. Should this be so, conversation viva voce by telegraph will be a fait accompli." (


"The day will come when the man at the telephone will be able to see the distant person to whom he is speaking." (




"When I have worked a long time on one thing, I make it a point to bring all the facts regarding it together before I retire." (Interview in How They Succeeded; Bell Telephone Talk, 1901)


"Concentrate all your thoughts upon the work at hand. The sun's rays do not burn until brought to a focus." (Interview in How They Succeeded; Bell Telephone Talk, 1901)


"You cannot force ideas. Successful ideas are the result of slow growth. Ideas do not reach perfection in a day no matter how much study is put upon them." (Interview in How They Succeeded; Bell Telephone Talk, 1901)
