In my opinion Marconi contributed the most because he was the one that made the first successful transatlantic radiotelegraph mesage that travelled allt he way from England to Canada and showed that telegraphy could be transmitted by the radio instead of wire.This tenchnology because very useful when transmitting important imformation that helped capture criminals. Today policemen are able to communicate with eachother in different locations and inform one another on the whereabouts of a wanted criminal.
