But it was Guglielmo Marconi, an Italian inventor, who proved the feasibility of radio communication. He sent and received his first radio signal in Italy in 1895. In 1899, he flashed the first wireless signal
Through his experiments in wireless telegraphy, Nobel Prize-winning physicist/inventor Guglielmo Marconi developed the first effective system of radio communication.
One of the major accomplishments of the late nineteenth-century applied physics was, as it is well known, the development of wireless telegraphy by Guglielmo Marconi, future Nobel laureate. In this paper, we will explore what scientific debt, if any, Marconi had toward another Italian physicist,...

This led to the work of Guglielmo Marconi of Italy, Lee de Forest of the United States, and many others, which laid the foundations of radio engineering. In 1930 the term electronics was introduced to embrace radio and the industrial applications of electron tubes. Since 1947, when the ...
