Question

Alexander Graham Bell
Alexander Graham Bell, best known for his invention of the telephone, revolutionized
communication as we know it. His interest in sound technology was deep-rooted and
personal, as both his wife and mother were deaf. While there’s some controversy over
whether Bell was the true pioneer of the telephone, he secured exclusive rights to the
technology and launched the Bell Telephone Company in 1877. Ultimately, the talented
scientist held more than 18 patents for his inventions and work in communications.

Birthplace
Alexander Graham Bell was born in Edinburgh, Scotland, on March 3, 1847.
Bell’s father was a professor of speech elocution at the University of
Edinburgh and his mother, despite being deaf, was an accomplished pianist.
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.

Telephone
In 1871, 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.
