History of Communication
History of Communication Animals have their own methods of communication. For example Dolphins use sound to communicate with other dolphins and to echolocate when hunting. From the early history of human existence there have been many ways of communicating each other. People from different parts of the world use a variety of languages to express their thoughts. Gradually civilization thrived and ways of communicating other continents became a general need to build up political and economical inter-relationships among them. We find many curious and interesting methods of communication in the history of the world. Sri Lankan history reveals that messages were sent by birds often. And some messages were named after the bird that carried it. The postal system was one of the early forms of communication. Chou Dynasty created his own postal system in 1000 B.C. The mail would travel on a horse to the next pass. Romans had their own system called the “Cursus Pubius”, they used foot messengers. Genghis Khan made an early postal system using homing pigeons. Middle Age in European history is a very important period. After the invention of the printing machine people in Europe gathered knowledge by reading. They started thinking. Hence, many inventions and theories came forward. Among them were telegraph, telephone, television and radio. British inventors Sir Charles Wheatstone and William F. Cook invented the telegraph in 1837. Samuel Morse invented the telegraph communication system called the Morse code. It had long and short electrical impulses referring as dots and dashes. Each impulse is either a letter or number.

Lawyers, Patents, and the Judgments of History CHRISTOPHERBEAUCHAMP Who invented the telephone? In the United States, this question has a widely known answer. Alexander Graham Bell routinely ranks among the hundred “greatest” or “most influential” Americans, whether chosen by historians or internet polls.1 His cry of “Mr. Watson—come here—I want to see you,”al- though often misquoted, is one of the best-known exclamations in Amer- ican history.2 More than one hundred and thirty years after the event, Bell and Watson’s first telephone call remains a classroom staple: a standard de- vice for teaching Americans about the nation’s inventive past, and even for placing technological change at the center of mainstream history.3 Christopher Beauchamp is the Sharswood Fellow in Law and History at the University of Pennsylvania Law School. In an earlier form, this essay received the Levinson Prize of the Society for the History of Technology. The author is grateful for the advice of Anisha Dasgupta, Martin Daunton, Richard John, Robert MacDougall, Christine MacLeod, John Staudenmaier, and four anonymous referees for T&C.

Telephone – Inventions That Revolutionized the World
Telephone – Inventions that Revolutionized the World December 14, 2018 First Publication Date: 27th November 2010 The most common devices used for transmitting the voice signal over a greater distance are pipes and other physical mechanical media. All of us as a child must have used this form for communication. Another device used for centuries for voice communication is lover’s phone or tin can telephone. The classic example is the children’s toy made by connecting the bottoms of two paper cups, metal cans, or plastic bottles with string. But the invention which changed the entire scenario of the communication is the telephone. It revolutionized the entire communication system. People could hear the voice of their loved ones staying miles away. Telephone comes from the Greek word tele, meaning from afar, and phone, meaning voice or voiced sound. Generally, a telephone is any device which conveys sound over a distance During the second half of the 19th century many well-known inventors were trying to develop an acoustic telegraphy for economic telegraph messages which included Charles Bourseul, Thomas Edison, Antonio Meucci, Johann Philipp Reis, Elisha Gray, and Alexander Graham Bell. The ‘speaking telegraph’ or in simple terms ‘telephone’ emerged from the creation and gradual improvement of telegraph. The invention of telephone has been one of the most disputed facts of all time. Credit for the invention of the electric telephone is never an ending dispute and new controversies over the issue keeps arising from time-to-time. The Elisha Gray and Alexander Bell controversy raises the question of whether Bell and Gray invented the telephone independently and, if that’s not true, then whether Bell stole the invention from Gray.

The word comes from a combination of the Greek tele, meaning ‘far’, and the Latin communicatio- nem, meaning to impart, to share – literally: to make common.
