UGLICHNO MARCONI
( 1874 - 1937)
Marconi is the inventor of wireless telegraphy and radio. He was born at Bologna in Italy on 25 April 1874. He was encouraged by his mother to do research. Marconi was conducting experiments in his father’s estate after he studied physics in a technical school. He showed interest in sending telegraphic messages without the help of wire. He had come to understand that Heirich Hertz had believed that radio waves could be used to carry messages. Marconi sent wireless messages. He positioned an electric bell in between many instruments in one corner of the room. He went to the other corner of the room and pressed the Morse Key. (Samuel Morse. The inventor of telegraphy). To his surprise the electric bell placed at a distance of 30 feet rang. The ringing of the bell with the radio waves was possible. In an another instance, he placed his self made transmitter on one side of a hill and received the message on the other side. This experiment made him to send messages to long distance also. By 1897 he had succeeded in rado communication over a distance 20 kilometres. He established the Marconi company in 1897. In 1899, He transmitted a radio signal across the English channel a distance of nearly 50 kilometres.
Marconi’s invention made radio broadcasting to begin in England on 14th February 1922. Radio is the term applied to methods of signaling through space, without connecting wires, by means of electromagnetic waves generated by high frequency alternating current.
Marconi was made the president of the Royal Italian Academy in 1930. Several changes took place in radio communication after its invention by Marconi. He lived to see all of them. He died on 20 July, 1937 in Rome. In 1909 Marconi received the Nobel Prize for his invention.
