Steinicke was born as the son of a Jewish merchant family in the Uckermark . In Berlin he enthusiastically followed the November Revolution . He joined the Communist Youth Association , studied economics from 1923 and joined the KPD that year for conspiratorial reasons under the name Günter Reimann . He was one of the supporters of Rosa Luxemburg . From 1925 he held a leading position in the " Revolutionary Student Union ".
He became a graduate economist and businessman and wrote as an editor for (world) economic issues for the KPD central organ Rote Fahne . In 1930 he was replaced by Jürgen Kuczynski and traveled to the Soviet Union as a freelance writer, where he came to the conclusion that the Stalinist state socialism with recuperated industrialization based on the western model was not practicable.
When the Gestapo tried to arrest him in the summer of 1933, he fled to London via Prague , Vienna , Paris and Amsterdam (1937) . In 1936 he broke with the KPD and went to the USA in 1938. In 1939, Vanguard Press in New York published his book “The Vampire Economy”, written in Amsterdam, about the Nazi economy in Germany. From 1940 he worked at the International Statistical Bureau and wrote other books. His sister Margot died in Auschwitz concentration camp .
After the end of the war, he campaigned against the Morgenthau plan to de-industrialize Germany and for aid deliveries. He also kept in touch with his friend Herbert Wehner , who was stuck in Sweden. The letters appeared in 1998 under the title Between Two Epochs .
After the Second World War , he founded an agency in 1947 that published weekly International Reports on Finance and Currencies . The agency became an institution in the financial world that received its information from 50 offices and contributors around the world. It provided business owners, banks, and tax officials in the United States with statistics on financial markets. He sold the paper to the Financial Times publisher in 1981 .
On his 90th birthday, Reimann was the founder of the science award , which was awarded by the Rosa-Luxemburg-Stiftung Sachsen e. V. is awarded to students and young scientists every two years. On December 11, 2003, he was awarded the Cross of Merit, First Class . On February 19, 2004, this honor was presented to him by the German Consul General in New York, Uwe-Karsten Heye (SPD). With his life's work he has made a contribution to German-Jewish reconciliation.
