17David Edward HughesInventor of the carbon microphone who transmitted and received radio signals in London in 1879, years before Hertz, though nobody believed him.
18Édouard BranlyFrench physicist whose 1890 coherer was the first practical detector of radio waves and sat inside the earliest wireless receivers.
19John Ambrose FlemingDesigned the Poldhu transmitter for Marconi's 1901 transatlantic signal and invented the thermionic valve that became radio's first detector tube.
20Valdemar PoulsenDanish engineer whose arc transmitter generated continuous radio waves, powering the first long-distance voice and naval stations before valves took over.
21David SarnoffProposed the 'radio music box' and, as head of RCA, turned wireless into mass broadcasting and founded the NBC network.
