INTRODUCTION
A few centuries ago, there were only a few kinds of communication that people can use. They could speak to each other, they can use smoke as a means of communication to send their message from one place to another or they could use mail. Later on, they also had telegram. During the modern age, telephone is one of the most important inventions in the field of communications. It is a disruptive technology that had made other means of communication become obsolete. Nowadays, it has played an irreplaceable role in our daily life but not many people know about the origin and history of telephone. This assignment is to briefly introduce to you the history of telephone. It has a long history so I broke it into 4 periods: Early Telephone Development, The Beginning (1876-1900), The New Century (1904-1940) and Modern Time (1940-Today)
HISTORY OF TELEPHONE
Early Telephone Development
In 1729, An English chemist named Stephen Gray had successfully transmitted electricity over a wire. In 1746, Dutchman Pieter van Musschenbroek and German Ewald Georg von Kleist independently developed the Leyden jar which was named after its Holland city of invention. It is a device that was used by early experimenters to help build and store electricity. It was also called a "condenser" because many people considered electricity as fluid or matter that could be condensed. Over the years these jars were used in countless experiments, lectures, and demonstrations

In 1820, a Danish physicist Christian Oersted discovered electromagnetism, the critical idea needed to develop electrical power and to communicate. Oersted discovered that an electric current creates a magnetic field but he didn’t know if a magnetic field could
