Georg Stadtmüller (Bürstadt, Hessen, March 17, 1909 - Passau, November 1, 1985) was German historian and Albanologist.He studied German history, classic and oriental philology and history in Freiburg in period 1927-1931.
He was president of History department on Munich University, specialist for history of European Orient and history of Albanians.
In his 1942 work he published the controversial thesis in which he traced the origin of Albanians back to the region of Mat.
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.
Stadtmüller founded the Albanian Institute in Munich, Germany, in 1963.
Stadtmüller is the author of 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.
