De Forest Audion, 1906.
Lee De Forest, (født 26. august 1873 Iowa, død 30. juni 1961 Los Angeles) var en amerikansk opfinder som lavede 300 patenter. De Forest opfandt elektronrøret af typen trioder i år 1907. De Forest sagde at han ikke vidste hvorfor det virkede, det virkede bare.
Denne triode blev døbt audion, og den var den revolutionerende "nøglekomponent" til en elektronisk forstærker; den kunne forstærke et svagt elektrisk signal til et stærkere. De Forest er en af elektronikalderens fædre, da audion-elektronrøret hjalp med den omfattende udbredelse af elektronik.

An early De Forest audion tube, the first electron tube that could amplify. The first triode, or tube with three electrodes, a filament, grid, and plate, the audion was invented in 1906 by American engineer Lee De Forest. The top metal electrode is the plate. The zigzag metal wire partly visible under it is the grid. The filament was originally under that, attached to the wires at left, but has burned out. As many Audions did, this model had two filaments (indicated by the four filament supply wires) so that when one burned out the "spare" could be used. The filament wires were attached to the screw terminal at left, while the grid and plate terminals were brought out through the right end of the glass envelope to the two wires at right. Tube belongs to History of San Jose, Perham Collection of Early Electronics.
