Alexander Meissner
Austrian engineer and physicist (1883–1958)
Alexander Meissner (September 14, 1883 – January 3, 1958) was an Austrian engineer and physicist. He was born in Vienna and died in Berlin.
His field of interest was: antenna design, amplification and detection advanced the development of radio telegraphy. In March 1913 he discovered the principle of positive feedback independently of Edwin Armstrong, and by applying positive feedback to vacuum tube amplifiers, Meissner co-invented the electronic oscillator, which became the basis of radio transmission by 1920 and has innumerable uses today. The inductively-coupled oscillator circuit he invented is today known as the Meissner oscillator.
The public source identifies “Alexander Meissner” as austrian engineer and physicist (1883–1958). This brief keeps that definition visible, then builds a research path around Alexander, Meissner and Austrian.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Alexander Meissner”, the useful work is to connect “austrian engineer and physicist (1883–1958)” to the records capable of establishing context and consequence.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Jan 27, 2026. The linked authority identifier is Q77736. VIAF identifies the subject as 81068249. 3 of 3 selected statements include explicit references; 1 carry qualifiers and 1 use preferred rank. The first chronological checks are 1883, 1958, 1913 and 1920.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
