Otto Corbach (1877–1938) was a German journalist and publicist.
Corbach was born in Herscheid and moved to Qingdao in 1900, at that time the administrative centre of the Kiautschou Bay concession. He had a position as an accountant, probably for Kappler & Sohn as he was staying in Kappler's house. He started editing the paper Deutsch-Asiatische Warte (Germa-Asian Viewpoint).[1] However in 1902 he got in trouble for criticising the authorities and returned to Germany.[1] He worked as an editor first in Kassel and then in Wroclaw before moving to Berlin.[1]
Corbach was a friend of Franz Pfemfert and shared his readiness to use the writings of Friedrich Nietzsche to criticise Wilhelminian Germany.[2] He was a regular contributor to Pfemfert's Die Aktion.
