When in 1895 twenty-one-year-old Guglielmo Marconi made his first wireless transmission over land, he became the boy wonder of the world. When subsequently, he made similar transmissions across the Atlantic Ocean, thus proving to the world that his radio-related inventions had immediate and wide-spread applications for all of humanity, young Marconi ushered in the Age of Communication. The life, the works, the character of one of the greatest scientists of this Century, Guglielmo Marconi, the inventor of the Radio, are described in this carefully documented, impassioned and deeply involved book by an exceptional witness: his wife Maria Cristina. He was called 'The genius who gave a voice to silence'. Acclaimed by the whole world, the recipient of the most prestigious honours and decorations, he never lost his innate modesty and discretion even at the height of his success.
