HASENAUER, hä'ze-nou'ẽr, Karl, Baron von (1833-94). An Austrian architect, born in Vienna, where he studied at the academy under Van der Nüll and Siccardsburg, and obtained the first prize in 1854. After having traveled extensively in Germany, Italy, France, England, and Scotland, he entered upon an active career in Vienna, was again awarded the first prize for architecture at the art exhibition of 1864, became a member of the Academy of Fine Arts in 1866, and honorary member of the Institute of British Architects in 1868. Among a number of private palaces built by him, the Palais Lützow is to be noticed as one of the finest houses in Vienna, but his most important work was the erection of the magnificent Imperial Museums of Art and Natural History (1872-91) in purest Renaissance style, after his own and Semper's designs. He also built the new Hofburg theatre (completed 18S8), and designed the addition to the Imperial palace. He was architect for the buildings of the Vienna Exposition in 1873, and was raised to a baronetcy in the same year.
