Bell Patents the Telephone

Where would we be without the telephone? 29-year-old Alexander Graham Bell patented the first telephone March 7, 1876. The first phone call to his assistant was March 10th, 1876.

The Scottish-born Bell worked in London with his father, Melville Bell, who developed Visible Speech, a written system used to teach speaking to the deaf. In the 1870s, the Bells moved to Boston, Massachusetts, where the younger Bell found work as a teacher at the Pemberton Avenue School for the Deaf. He later married one of his students, Mabel Hubbard.

While in Boston, Bell became very interested in the possibility of transmitting speech over wires. Samuel F.B. Morse's invention of the telegraph in 1843 had made nearly instantaneous communication possible between two distant points. The drawback of the telegraph, however, was that it still required hand-delivery of messages between telegraph stations and recipients, and only one message could be transmitted at a time. Bell wanted to improve on this by creating a "harmonic telegraph," a device that combined aspects of the telegraph and record player to allow individuals to speak to each other from a distance.

With the help of Thomas A. Watson, a Boston machine shop employee, Bell developed a prototype. In this first telephone, sound waves caused an electric current to vary in intensity and frequency, causing a thin, soft iron plate – called the diaphragm – to vibrate. These vibrations were transferred magnetically to another wire connected to a diaphragm in another, distant instrument. When that diaphragm vibrated, the original sound would be replicated in the ear of the receiving instrument. Three days after filing the patent, the telephone carried its first intelligible message – the famous "Mr. Watson, come here, I need you" – from Bell to his assistant.

Bell's patent filing beat a similar claim by Elisha Gray by only two hours. Not wanting to be shut out of the communications market, Western Union Telegraph Company employed Gray and fellow inventor Thomas A. Edison to develop their own telephone technology. Bell sued, and the case went all the way to the U.S. Supreme Court, which upheld Bell's patent rights. In the years to come, the Bell Company withstood repeated legal challenges to emerge as the massive American Telephone and Telegraph (AT&T) and form the foundation of the modern telecommunications industry.
