Alexander Graham Bell was born in 1847 in Edinburgh, Scotland, into a family devoted to the study of speech and sound; his father specialized in teaching speech to the deaf. Bell inherited and deepened this interest, especially after both his mother and later his wife became deaf, which led him to dedicate much of his life to serving and educating deaf people.
Bell emigrated to Canada and then the United States, where he taught the deaf while experimenting with transmitting sound over electrical wires. In 1876 he patented the telephone, a device that revolutionized human communication and ushered in an entirely new era of connecting people across distances.
Beyond the telephone
Bell founded the Bell Telephone Company, which grew into one of the world's largest telecommunications firms, and continued research in other fields such as aviation and the “photophone,” a device for transmitting sound via light. Until his death in 1922, he remained an active advocate for deaf education, in honor of his mother and wife.
