Marconi
He improved the system for receiving electromagnetic waves and laid the foundations for modern antennas.
Built a transmitter powerful enough to send messages across the Atlantic Ocean.
During the 19th century his discovery predicted radio waves in his mathematical work
He discovered the photoelectric effect, the propagation of electromagnetic waves and ways to produce and detect them.
Made the first findings on long-distance transmission of wave signals through a wireless system using telegraphs, could transmit Morse code for only a couple of miles.
