Loomis was able to make a meter connected to one kite cause another one to move, marking the first known instance of wireless aerial communication. Guglielmo Marconi: an Italian inventor, proved the feasibility of radio communication. He sent and received his first radio signal in Italy in 1895. By 1899 he flashed the first wireless signal across the English Channel and two years later received the letter S, telegraphed from England to Newfoundland. This was the first successful transatlantic radiotelegraph message in 1902.
