[34] These initial forays into experimentation with sound led Bell to undertake his first serious work on the transmission of sound, using tuning forks to explore resonance. Though inventions like the Corliss steam engine seemed to be the mightiest, the telephone commanded attention for its utility to the average person. Bell was the companys technical adviser until he lost interest in telephony in the early 1880s. Bell travelled the country promoting his invention, even demonstrating the device to Queen Victoria, who was so amused she asked to keep the temporary installation in place. That was the foundation of the company that would become AT&T - a brand that is now synonymous with innovation in communications.

[149], Although Alexander Graham Bell is most often associated with the invention of the telephone, his interests were extremely varied. In 1907 Bell founded the Aerial Experiment Association, which made significant progress in aircraft design and control and contributed to the career of pioneer aviator Glenn Hammond Curtiss. The harmonic telegraph served as the basis for the modern telephone. Bell was born on March 3, 1847, in Edinburgh, Scotland. [18] Bell and his siblings attended a Presbyterian Church in their youth. But could Bell truly lay claim to inventing the telephone? Bell received numerous honorary degrees from colleges and universities to the point that the requests almost became burdensome.

For his work, Bell was awarded the title of Honorary Chief and participated in a ceremony where he donned a Mohawk headdress and danced traditional dances.

Alexander Graham Bell's role as a teacher for deaf individuals and the presence of his deaf wife and mother inspired him to develop his electrical speech machine, or telephone. In 1880 the French government awarded Bell the Volta Prize, given for achievement in electrical science. After the First World War, work began again on the HD-4. His wedding present to his bride was to turn over 1,487 of his 1,497 shares in the newly formed Bell Telephone Company. Associate Professor of History, University at Albany, State University of New York.
