Alexander Graham Bell, (born March 3, 1847, Edinburgh, Scot.—died Aug. 2, 1922, Beinn Bhreagh, Nova Scotia, Can.), Scottish-born U.S. audiologist and inventor. He moved to the U.S. in 1871 to teach the visible-speech system developed by his father, Alexander Melville Bell (1819–1905). He opened his own school in B...

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.

The Scottish-born Bell had a lifelong interest in the nature of sound. He was born into a family of speech instructors, and his mother and his wife both had hearing impairments. While ostensibly working in 1875 on a device to send I then shouted into M [the mouthpiece] the following sentence: "Mr. Watson, come here -- I want to see you." To my delight he came and declared that he had heard and understood what I said. I asked him to repeat the words. He answered, "You said 'Mr. Watson -- come here -- I want to see you.'" We then changed places and I listened at S [the speaker] while Mr. Watson read a few passages from a book into the mouthpiece M. It was certainly the case that articulate sounds proceeded from S. The effect was loud but indistinct and muffled. Watson's journal, however, says the famous quote was: "Mr. Watson come here I want you." After years of litigation, Bell's patents eventually withstood challenges from Gray and others -- perhaps by right, perhaps by virtue of bigger backer...

It’s an aspect of modern life most of us would struggle to live without. But until the late 19th century, the quickest way to communicate was by letter—made faster with the advent of the railways, but still far from instantaneous. The But how did technology advance to allow us to send and receive sound communications? Science Museum Group collection Bell in 1876, aged 29 In the 1870s, Scotsman Hubbard and Bell discovered that they shared an interest in mechanical and electrical inventions, especially telegraphy. Later, in Boston, Bell began to investigate ways of putting his knowledge of musical pitch to use in electric telegraphy. His ‘harmonic telegraph’ was designed to transmit several messages along the same wire by using tuned electromagnetic reeds to send and receive multiple pitches—or frequencies—simultaneously. This device was designed as an improvement on conventional telegraphy, not as a telephone. Nevertheless, Bell began to speculate about the possibility of being able to hold conversations over long distances. Early type of Bell transmitter with membrane diaphragm.

It’s often said that the most important role anyone can have is that of a teacher. This maxim was undoubtedly true of Alexander Graham Bell, who dedicated his life to teaching the deaf and hard of hearing how to communicate more efficiently. His work as a teacher not only helped countless students participate as equals in society but also led to some of his most important discoveries and inventions. Let’s explore the legacy of Alexander Graham Bell as an educator and discuss how his work in the field of deaf education came to be his lifelong passion. Early Life as an Educator Though he is most remembered for his work as an inventor, Alexander Graham Bell began his career as a teacher. At only 16, he started his first teaching job as a student teacher in Edinburgh, tutoring school-aged boys in music and elocution in exchange for a small stipend, board, and Latin and Greek lessons. It was only natural that Alexander taught elocution. His father and grandfather were “elocution experts,” or what is known today as After Alexander completed his tenure at the boarding school, he and his father toured Great Britain, meeting with linguistic experts to share the visible speech alphabet and advertise its utility. In learning the visible alphabet, the deaf and hard of hearing could learn how to articulate sounds without necessarily being able to hear them. This was a cause close to his heart, as Alexander’s mother had been born deaf. Alexander spent his early adulthood studying under ...
