RAU, row, Charles, American archæologist: b. Verviers, Belgium, 1826; d. Philadelphia, Pa., 25 July 1887. He was educated at the University of Heidelberg and came to this country in 1848, where he engaged in teaching. From 1875 until his death he was curator in the National Museum at Washington, D. C. and devoted himself to the study of American archæology, on which he became a recognized authority. He wrote ‘Early Man in Europe’ (1876); ‘The Palenque Tablet in the United States National Museum’ (1879); ‘Articles on Anthropological Subjects, 1853-1877’ (1882). He left unfinished a work on the types of early American implements, and what was projected to be an exhaustive record of American archæology. His great library and collections were bequeathed to the National Museum.
