Who they are
Alexander Graham Bell (1847–1922) was born in Scotland to a family that had for generations taught speech to the deaf, and he himself long studied acoustics and hearing technology, a background that directly prompted him to explore the technical path of converting sound into an electric signal and back into sound. In 1876 he patented telephone technology and that same year successfully completed the first telephone-call experiment, transmitting over a wire to his assistant Thomas Watson the famous line "Mr. Watson, come here, I want to see you." On the day of the telephone patent application, another inventor, Elisha Gray, also filed a patent for a similar device of close principle, and the two thereafter fell into a years-long lawsuit over patent rights, the court at last ruling Bell held priority, but this dispute is still an ongoing topic in the history of technology. Bell thereafter founded the Bell Telephone Company (which later became AT&T), and the spread of the telephone network fundamentally reshaped how human society communicated instantly at a distance, directly giving rise to the thread of technological evolution of the telecommunications industry for more than a century after.

Key stories
The Man Who Taught the Deaf to Speak Invented the Telephone
Bell’s father invented a system of "visible speech" symbols to help the deaf learn pronunciation, and Bell himself long taught speech to the deaf (both his mother and his wife were deaf), and this experience of deep study of "how sound is produced and perceived" let him understand the physical nature of sound-wave vibration earlier and more deeply than a mere electrical engineer — precisely the key background to his being first to crack the core telephone problem of "converting sound into an electric signal."
Two Patents Filed the Same Day
On 14 February 1876 Bell filed a telephone patent application with the US Patent Office, and almost the same day the inventor Elisha Gray filed a patent for a liquid transmitter device of close principle, the two thereby falling into a long lawsuit over patent rights; though the court at last ruled Bell held priority and established his historical standing as "inventor of the telephone," this dispute is still a classic historical case for exploring the complexity of "priority of technological invention."
Version differences
Bell and Elisha Gray filed patents of close principle the same day, and the two camps thereafter waged a long lawsuit and historical dispute over "who was really the inventor of the telephone"; though the court at last ruled Bell held priority, some historians of technology still hold differing views on the fairness of the ruling.

"Bell" as the root of a sound-intensity unitThe logarithmic unit of sound intensity, the "bel" (and its common one-tenth unit the "decibel"), is named for him, and Bell Labs thereafter long remained one of the most influential industrial research institutions of the twentieth century.
