Ludwig Hausser, a German historian, born at Cleeburg, Alsace, Oct. 20, 1818, died in Heidelberg, March 17, 1867. He went in 1835 to Heidelberg to study philology; but through the influence of Schlosser he made also extensive historical researches, and in 1839 published Die deutschen Geschichtschreiber torn Anfange des Frankenreichs bis auf die Hohenstaufen. In 1848 he edited in conjunction with Gervinus, the Deutsche Zeitung, and was chosen a member of the chamber of Baden. In 1850 he accepted a professorship in Heidelberg, but continued to take an active share in politics, and in 1860 returned to the chamber, where he was a warm supporter of the liberal ministry. Among his most important historical works are Deutsche Geschichte vom Tode Fried-richs des Grossen bis zur Grundung des Deutschen Bundes (4 vols., Berlin, 1854-7), Geschichte der Franzosischen Revolution (1867), and Geschichte des Zeitalters der Reformation (1868; English translation by Mrs. R. Sterge, 1874). A complete edition of his works was commenced in Berlin in 1869.
