[9] He continued to work in Vienna until December 1937; by January 1938, no two months before Anschluss, Kranzmayer moved to the Bavarian Academy's sister project in Munich as the leader of the DBD.
Within five weeks after Anschluss, Kranzmayer reported with Anton Pfalz on their recording trips throughout Austria, what had by then become Germany's Ostmark, for Adolf Hitler's birthday present 1939.
[9] In the 2020s archival documents surfaced in which Kranzmayer celebrated in personal letters to Martin Wutte Hitler's take-over of power in Germany.
[9] As leader of a Nazi think tank that he helped to plan and set up with Gauleiter Rainer and SS-Ahnenerbe president Wüst, among others, he offered pseudo-scholarly assessments of the "purity" or "impurity" of the Slavic population in regards to German-dom by linguistic means.
[9] In particular, Kranzmayer's "race-biological account on language change", delivered as his July 1944 University of Graz inaugural lecture to great interest of Nazi politicians in Gau Styria, and distributed in several copies before war's end, and his role at the Bayerische Akademie der Wissenschaften and the Klagenfurt institute may require further scrutiny,[19] as Kranzmayer consistently interpreted his data from a vantage point of superiority of all things German.
