Germany did not have a Governor but a President (head of state) and a Chancellor (head of the government).
The German President at the time was Paul von Hindenburg, full name Paul Ludwig Hans Anton von Beneckendorff und von Hindenburg (born 2 October 1847, in Posen; died 2 August 1934 in Gut Neudeck, East Prussia).
The German Chancellor before Hitler was Kurt von Schleicher, who served from 4 December 1932 to 28 January 1933.
