315 280 Electricity and Basic Electronics John Ambrose Fleming, an English physicist, attached a light bulb fitted with two electrodes to a radio receiving system.
315 280 Electricity and Basic Electronics The next step was an invention by an American, Lee De Forest, who added an innovation component to Fleming's vacuum tube. It was a third electrode, called a grid, a network of small wires surrounding the cathode. The triode - the first amplifier http://en.wikipedia.org/wiki/Image:Triode_tube_schematic.svg
