Georg Stadtmüller (Bürstadt, Hessen, 17 March 1909 – Passau, 1 November 1985) was a German historian[2] and Albanologist.
In his 1942 work he published the controversial thesis in which he traced the origin of Albanians back to the region of Mat.
[4] Stadtmüller and later Stavro Skendi supported the controversial assertion about crypto-religious groups existing in the Balkans in all places where the population converted to Islam.
[6] Stadtmüller is the author of the hypothesis that Mat valley was summer pasturage for early Albanians.
According to this hypothesis Albanian language does not have loan words for flora and fauna found above 900m because this valley is situated in more than 1,000 m altitude and surrounded by mountains, admitting that flora and fauna found in lower ranges have loanwords originating in Slavic languages.
