The Telephone Revolution That Changed the World

In 1876, Bell was the first to receive the U.S. patent award. There were many other inventions that Bell invented. He invented the optical telecommunications, hydrofoils and aeronautics. In 1888, Alexander became one of the founders of the National Geographic Society.

In the 1870s, Alexander Graham Bell created the first device that could transmit speech electronically; it was called the first telegraph. However, Bell had some competition on the invention of the telegraph, (Elisha Gray) that ended up in a legal battle for the patent rights. The telegraph and telephone are both wire-based electrical systems that resulted in an improvement of a better telegraph. When Alexander experimented on electrical signals, the first telegraph was born and it continued on the next 30 years.

When inventing the telegraph, Bell used a musical or harmonic approach as the best choice, that way several notes could travel simultaneously along the same wire if the notes or signals were on the same pitch. By 1874, Alexander’s research improved a great deal that he informed his father-in-law, Gardiner Greene Hubbard, about creating multiple telegraphs. In March of 1875, Alexander Graham Bell met with the director of the Smithsonian Institute, Joseph Henry, who heard Bell’s conversation about the telephone and Joseph Henry approved of the idea. In 1875, Alexander Graham Bell and Thomas Watson got to work on using a device that would transmit speech electronically, which was about to become a reality. Different tones varied the strength of an electrical current in a wire. In order to succeed, they needed a transmitter with a membrane that would be capable of different electrical currents along with a receiver that could reproduce audible frequencies.

On June 2, 1875, Alexander Graham Bell was experimenting on his “harmonic telegraph” and discovered that he could hear sound over the wire which sounded like a twanging clock spring and then he called his partner, Thomas Watson, in the other room of the hotel that they were staying at telling Watson to come over. On March 10, 1876, Alexander Graham Bell created the first telephone that ended the multiple telegraphs. After that, the telephone became a huge success changing the world on how we, as people, communicate electronically through the air waves.

Alexander Graham Bell not only invented the telephone and telegraph, he also invented the photo phone and phonograph. He was a teacher, teaching the hearing impaired. He also founded AT&T, The National Geographic Society, Bell Labs, Bell System, and Aerial Experiment Association. Alexander Graham Bell went to the University Edinburgh, Scotland in (1864 – 1865) and the University London, London England (1868 – 1870).

On August 2, 1922, Alexander Graham Bell died from pernicious anemia at the age of 75 years old.
