Guglielmo+Marconi+(inventor)

Carlos P. Pd 5

Guglielmo Marconi was born in Bologna, Italy, on April 25, 1874. Macaroni's father was Italian and his mother Irish. As a boy he took interest in physical and electrical science and studied the works of Maxwell,Hertz, Righi, Lodge and others. Guglielmo did not go to real school until he was twelve. His first school was in Florence and he disliked it. He was still shy and the other boys teased him since he could hardly speak Italian. Guglielmo decided to become a naval officer, unfortunately he failed the test.

His relationship was his father wasn't to well because Guglielmo would dismember electrical devices and constructing new gadgets as "scientific rubbish." His relationship with his mother was closer. She bolstered his scientific interests by giving him the old attic in which to do his experiments. One day while he was vacationing with his half-brother Luigi read an article about the works of physicist, Heinrich Hertz. He immediately saw the exciting opportunities of using these waves for sending and receiving messages without wires.

In 1894, when he start working he used coil for increasing voltages, a spark dis charger controlled by a Morse key( which is a switching device to end Morse code), and a coherer(a device made to find radio waves) as the receiver. After a few tests he improved the coherer, then a few more systematic tests and showed that the range of signaling was increased by using vertical antenna with a metal plate or cylinder at the top of the pole connected to a similar plate on the ground. The range was now about 1.5 miles, enough to convince people that he had potential in this new system of communication.



Guglielmo Marconi was just 22 years old in 1896, but he already made his first public demonstration of wireless telegraphy. He moved on to London and found an assistant named Sir William Preece, the chief engineer of the post office. He gave more successful demonstrations using balloons and kites giving him more signals up to 6.4 km on Salisbury Plain and nearly 14.5 km across the Bristol Channel. 1897 Marconi went to La Spezia, and established with Italian warships at distances up to 19 km.

Alright i can keep going on and on of what he did, but lets get to Important Facts and why they are important.

1. He helped in a Wireless telegraph and Signal Company. Why? Because this is what he wanted to do. For a year or two they were strictly devoted to advancing radiotelegraph. By 1900 it was now called Macaroni's Wireless Telegraph Company.

2. He made the Marconi International Marine Communication Company. Why? Was establish for purpose of installing and operating services between ships and land stations. This gave a worldwide excitement which led a American Marconi Company. He reviewed a patent no.7777 for Improvements in Apparatus for Wireless Telegraphy.

3.  He acquired numerous patents, though probably his most famous one, No. 7777, was his most famous one because it was a sign of good fortune.

4. In 1894 Marconi read that Heinrich Hertz, by inducing an electric spark to jump across a gap, had produced invisible waves that travel through space. Marconi realized that the waves might be used to send wireless messages similar to the dot-and-dash messages sent by telegraphs. He began experimenting and within a year was sending messages over distances of more than a mile (1.6 km). Widespread use of radio was assured on December 12, 1901, when assistants in England sent the first transatlantic signals to Marconi in Newfoundland, a distance of some 4800 km (3,000 miles).
