October 20, 1906: Dr. Lee De Forest announces Triode
Dr. Lee De Forest announced his three-element electrical vacuum tube on this day in 1906. The tube later came to be known as ‘Triode’.
A triode is an electronic amplifying vacuum tube consisting of three electrodes inside an evacuated glass envelope: a heated filament or cathode, a grid, and a plate (anode).
Dr. Forest made the triode the first practical electronic amplifier by adding a grid electrode to the thermionic diode (Fleming valve). It is known as the ancestor of other types of vacuum tubes such as the tetrode and pentode.
