"Johann Friedrich Gottlieb Unger (1753 in Berlin – December 26, 1804 in Berlin) was a German printer and publisher.
He was the fifth son of the printer Johann Georg Unger (October 26, 1715 in Goes bei Pirna – August 15, 1788 in Berlin) and his wife Susanna Katharine (maiden name: Strucken). He took on an apprenticeship at the print shop of the Oberhof printer Georg Jacob Decker. In 1779 Unger requested a print shop for himself and in January 1780 he was granted one. Later, he expanded it to a publishing bookseller, in which he published works by Johann Wolfgang Goethe, Friedrich Schiller, Friedrich Schleiermacher as well as August and Friedrich Schlegel." - (en.wikipedia.org 30.10.2019)
