Alexander Graham Bell was born in Edinburgh, Scotland, on March 3, 1847. Son of Alexander Melville Bell, educator of the deaf, and Eliza Grace Symonds, who became deaf at a young age.
In addition to being self-taught, he learned a lot from his father and grandfather, who were authorities in speech correction and training for hearing impaired people.
In 1861, he attended the conferences held at the University of Edinburgh and University College in London. That same year he began teaching music and diction at the Weston House Academy in Elgin, Scotland.
From 1864, he became a master and resident of the Weston House Academy, studying and teaching speech correction techniques.
In 1868 in London, he became his father's assistant and took his place when he traveled to the United States to teach courses in speech therapy.
In 1870, after the death of his two younger brothers, stricken with tuberculosis, the Bell family moved to Canada.
They buy a house in Brantford, Ontario, which became known as the "Melville House" and is today called the "Bell Manor."
Alexander Graham Bell lectured in Boston about his father's phonetic symbol system.
In 1872, he founded a Massachusetts preparatory school for deaf-mute teachers. The following year he became professor of vocal physiology at Boston University.
To carry out his research, he received financial help from the parents of two of his students. One of them, a lawyer and businessman, who would become his father-in-law. In 1875, he registered the patent of a telegraph.
In 1876, he returned to Boston and after six months of work presented a rudimentary apparatus, which he himself would later refine. The phone was invented.
Graham Bell began a complicated legal struggle over patent issues with Italian Antonio Meucci. That same year the phone is presented at an exhibit in Philadelphia.
