The Imperial Natural History Museum or Imperial Royal Natural History Court Museum of Austria-Hungary was created by (Kaiser) Emperor Franz Joseph I during an extensive reorganization of the museum collections, from 1851–1876, and opened to the public on August 10, 1889. Located in Vienna, the Museum was named in German as "K.k. Naturhistorisches Hofmuseum" (with "Hofmuseum" translated as "Court Museum"). Later, the Museum became part of the Natural History Museum of Vienna, Austria (in German, "Naturhistorisches Museum Wien" or NHM-Wien).
