The main take-away... Creativity is a necessity for our survival !

Guglielmo Marconi: Inventor and Visionary

Heinrich Hertz (1857-1894)

The young Marconi: undergraduate passion • 1894 in Villa Griffone

Celestini’s hill: seizing the opportunity

Believe in your intuition

Facing resistance and irony

A man with a destiny (Titanic 1912)

Marconi: The visionary

Forecasting Entertainment in 1922 “I think I am safe in saying that if radio has already done so much for the safety of life at sea, for commerce, and for commercial and military communications it is also destined to bring new and, until recently, unforeseen opportunities for healthy recreation and instruction into the lives of millions of human beings.” [Guglielmo Marconi, 1922]

Forecasting Personal Communications in 1937 Broadcasting [...] is not - in my opinion - the most significant part of modern communications, in so far as it is a one way communication. A far greater importance attaches, in my opinion, to the possibility afforded by radio of exchanging communications wherever the correspondents may be situated : whether in mid-ocean, or on the ice pack of the pole, or in the waste of a desert, or above the clouds in a airplane! [Guglielmo Marconi,”The Significance of Modern Communication”, March 1937]

The world’s first mobile radio terminal! Circa 1900

Marconi’s legacy: innovation pro bono humanitate In radio we have a fitting tool for bringing the people of the world together, for letting their voices be heard, their needs and aspirations be manifested. The significance of this modern means of communication is thus fully revealed: a wide channel for the improvement of our mutual relations is available to us; we have only to follow its course in a spirit of tolerance and sympathy, solicitous of exploiting the achievements of science and human ingenuity for the common well. [Guglielmo Marconi,”The Significance of Modern Communication”, March 1937]
