Guglielmo Marconi: the Pioneer of Wireless Communications

In 1909 Marconi was awarded the Nobel Prize in Physics. Although very young - he was thirty-five-years old - he had proved how far his system of wireless telegraphy could work, from the first experiments carried out near Bologna, till the first commercial transatlantic service inaugurated in 1907. This successful path will be presented as well as some considerations on Marconi's legacy in telecommunications, 100 hundred years after his most prestigious award.
