Omas Guglielmo Marconi Roller "100 years of radio".
The Italian physicist Guglielmo Marconi was the inventor of the radiotelegraph system. In 1909, he shared the Nobel Prize in physics with Karl Ferdinand Braun for his contribution to the development of wireless telegraphy. During the era of Heinrich Hertz it was discovered that electromagnetic radiation could be produced and detected and Marconi began to experiment alone with the equipment that he had built in his house, to demonstrate his purpose or use radio waves to create a system of practical wireless telegraphy. Marconi improved a series of components already known and adapted them to his system. The first financier of Marconi was his father, thanks to who he bought more supplies and in the summer of 1895 moved his project outdoors.
With more research and funds obtained in England, he created a device capable of extending to long distances, useful both commercial and military. This was followed by a series of protests to the British Government, and in March 1897, Marconi transmits signals in Morse code over a distance of about 6 kilometres (3.7 miles). In May 1897, he sent the first signal of the Morse code to the open sea.
Marconi made possible the wireless communication across the Atlantic Ocean, thanks to his invention there were contacts from and to the Titanic at the time of the disaster.
The OMAS celebrates this great inventor with a blue resin ballpoint pen which body is crossed by fine silver rings. The clip shows the symbol "straight kay" used in the Morse code. Without box.
