    FIRST EDITION, journal issue of Fleming's paper introducing the basic principle of the modern wireless valve. In 1904 Fleming, an electrical engineer who had worked with Thomas Edison's company in London, began experimenting with the currents in carbon filament lamps. He was able to demonstrate the idea of unilateral conductivity in wireless waves, paving the way for Lee DeForest and others to perfect the broadcasting of wireless signals. PMM 396.
