There are certain people that shared some contribution in the development of the telephone. These individuals are; Alexander Graham Bell, Hans Christian Oersted, Michael Faraday, Lee de Forest, William Shockley, Walter Brattain, John Bardeen, Robert Keck, Robert Maurer and Peter Schultz.
Alexander Graham Bell experimented the communication device called as the telegraph that was developed by Samuel Morse. With Bell’s knowledge in electricity, he developed his model of the liquid telephone. This was consisted with a wooden stand, a funnel as well as a cap of acid and copper wires. The telephone that was designed by bell uses the principles of
magnetism and it later evolve in different models. The invention of the telephone was credited to Alexander Graham Bell.An individual named Hans Christian Oersted was the responsible in the discovery of the magnetism. This discovery was unintentional, eventually happened when he was preparing a lecture in his laboratory. Hans Christian Oersted concluded that the current carrying conductors can produce a magnetic field. The discovery of magnetism became the principle of the electromagnets which was a major telephone component.
Michael Faraday did a discovery that is a reverse of the discovery of Hans Christian Oersted. He discovered that changing magnetic field produces or either induces current. Michael Faraday discovered what is now called as electromagnetic induction and he was being acknowledged as father of the modern electricity.
Joseph Henry further shows that an electromagnet
or electromagnetism is possible to be used in the communication process. Henry was able to demonstrate that electromagnetic current can attract iron bars, and can able to turn it and struck a bell nearby. This process is like making signal using the influence of electricity to a bell.Summing up the principles that were made by Oersted, Faraday as well as the other scientist, James Clerk Maxwell was able to hypothesize the existence of what is called as magnetic waves.
Twenty years passed when Heinrich Hertz showed the existence of the waves and Hertz called these waves as the radio waves.
After, Guglielmo Marconi was able to begin the wireless communication using the radio waves.
With the vacuum tube built by Lee de Forest a nationwide telephone system was developed.
Years had passed since then when William Shockley, Walter Brattain and John Bardeen developed the transistor, replacing the vacuum tubes that were used in the telephone networks.
Few years later, Robert Keck, Robert Maurer and peter Schultz was able to produce the first optical fibers. The developments of the optical fibers are considered as one of the breakthrough that creates a revolution in modern communication.
