Gnstav Friedrich Waagen, a German writer on art, born in Hamburg, Feb. 11, 1794, died in Copenhagen, July 15, 1868. After serving as a volunteer in 1813 - '14, he continued his art studies at Breslau, Dresden, Heidelberg, and Munich. He was employed in the preliminary labors for the new museum in Berlin, and in 1832 was appointed director of the portrait gallery in it. In 1844 he became professor of the history of art in Berlin. Besides a pamphlet on Egyptian mummies (1820), and a monograph on Hubert and Jan van Eyck, he published Kunstwerhe und Kunstler in England und Paris (3 vols., 1837-9), a translation of the English portion of which (London, 1838) formed the basis of his "Treasures of Art in Great Britain" (3 vols., 1854), and the supplementary volume, "Additional Art Treasures in Great Britain " (1857). His remaining works comprise Kunstwerhe und Künstler in Deutschland (-2 vols., 1843-5); Die Gemaldesammlung in der haiserlichen Ermitage in St. Petersburg (1864); Die vornehmsten Kunstdenkmaler in Wien (2 vols., 1866-'7); and essays on Rubens, Mantegna and Signorelli, Spanish art, etc, for Raumer's Historisches Taschenbuch and the Jahrbucher fur Kunstwissemchaft. A. Woltmann, K. von Ltitzow, and Bruno Meyer have collected his posthumous papers (Kleine Schriften, Stuttgart, 1875); and the "History of Painting: the German, Flemish, and Dutch Schools," based on Kugler's "Handbook," originally edited by him, was revised and rewritten by J. A. Crowe (London, 1876).
