Gustav Wilhelm Richard Sorge (6 April 1852 – 1 December 1907) was a German mining engineer.
Sorge was the son of a surgeon who practiced in Schilda. His uncle was Friedrich Adolf Sorge.[1] He specialized in the field of coal mining in Wettin, Saxony-Anhalt, Germany. He studied mining conditions and material handling technology.
Convinced that coal mining prospects at the Wettin Coal Mine were poor, he changed his emphasis to oil exploration, studying for several years in the United States.
From there he traveled to the oilfields near Baku in 1877 to set up a drilling technology workshop for the Otto Lenz machine factory in Sabunçu, Baku, concentrating on the field of deep drilling technology and the industrial equipment required for this purpose. In 1881 he founded his own company in his name.
He worked for Deutsche Petroleum-Aktiengesellschaft (DPAG) and the Caucasian oil company Branobel (of Robert, Ludvig and Alfred Nobel and others). He married Nina Semyonovna Kobeleva, born in Baku on April 20, 1867, into a working-class family and became the father of the famous spy, Richard Sorge (1895–1944) along with eight other children.
After his health deteriorated and he lost his lucrative contract, the family moved to Berlin-Lankwitz in 1898. There he worked as a director for the Disconto-Gesellschaft which had founded the German-Russian Naphta Society. In 1900 he prepared a report on the Romanian oil industry.
