Alexander Graham Bell is generally credited with inventing the telephone. He received U.S. Patent No. 174,465 on March 7, 1876, for an invention described as an improvement in telegraphy. Bell was born in Edinburgh, Scotland, and was living and working in Boston when he developed his telephone experiments.
Bell was not the only person trying to find a way to send speech through wires. Antonio Meucci, Elisha Gray and Johann Philipp Reis had also worked on devices that could transmit sound. That is why the history of the telephone is more complicated than simply saying that one man invented it.
Bell had been working on ways to improve the telegraph. Telegraph systems could send electrical signals over wires, but they could not carry ordinary human conversation. Bell became interested in the possibility of sending several signals at different frequencies and eventually began experimenting with a device that could reproduce speech.
On March 10, 1876, Bell was working with his assistant, Thomas Watson, in Boston. Bell was in one room while Watson was in another. During one of their tests, Bell spoke into his transmitter and Watson heard his voice through the receiver. Bell's famous words were recorded as, “Mr. Watson, come here, I want to see you.” This is generally regarded as the first successful transmission of understandable speech using Bell's telephone.
The story becomes more complicated when other inventors are considered. Johann Philipp Reis demonstrated a device called the “Telephon” in Germany in 1861. His apparatus could reproduce some sounds and musical tones, although it was not reliable at transmitting clear human speech.
Antonio Meucci also deserves a place in the history. The Italian immigrant developed a voice-transmission device during the 1850s and 1860s while living in the United States. He filed a patent caveat in 1871 but did not renew it after 1874. Meucci later became involved in a legal dispute surrounding Bell's patent.
Another important character was Elisha Gray. On February 14, 1876, he filed a patent caveat describing a way of transmitting speech by electrical means. Around the same time, Bell also filed a patent application of his own. The fallout from those filings would become one of the most controversial moments in the history of the telephone.
Bell's patent eventually became the foundation of a large business. He and his associates established the Bell Telephone Company in 1877, and telephone exchanges soon began appearing in American cities. A commercial telephone exchange opened in New Haven, Connecticut, in 1878.
Meucci’s contribution was officially acknowledged much later. In 2002, the U.S. House of Representatives passed a resolution acknowledging his work and contribution to the invention of the telephone. But the resolution did not legally trump Bell as the holder of the historic telephone patent.
