DeForest and the Triode[edit]

Why say that DeForest refined his audion into the triode? DeForest never actually understood how his device worked since it relied upon residual gases remaining in the glass tube. Langmuir invented the vacuum triode and fully understood its functioning. Moreover, the audion could not be used for amplification, only for detection. And one more thing: The thermionic effect was first discovered by Guthrie, not Edison. Why not give credit where it is due? Epaulard (talk) 05:42, 21 January 2010 (UTC)

Just to set the record straight: the Audion could amplify (although it only had a gain of about 5) and is considered the first amplifying tube and the first triode, as stated in numerous WP:RSs 1, 2, 3, 4 --ChetvornoTALK 20:56, 13 October 2013 (UTC)
