Julius Loewenberg (1800 - December 12, 1893) was a German Jewish printer, geographer, and author active in Berlin during the middle part of the 19th century. Loewenberg was born in the Duchy of Posen. He attended Yeshiva in Kleczewo (Poland) and graduated to the Protestant Gymnasium of Thorn before moving on to study Christian theology and geography at the Universtiy of Berlin. His works include various atlases, histories, and several translations of the works of Alexander von Humboldt, with whom he was apparently close. Loewenberg died in a Jewish retirement home in Berlin.
