The New International Encyclopædia/Mindeleff, Cosmos

MIN′DELEFF, Cosmos (1863—), An American archæologist, of Russian parentage. From 1882, when he was attached to the United States Bureau of Ethnology, he devoted himself to the study of the aboriginal habitations of New Mexico and Arizona. He became specially skilled in the modeling of these, and wrote articles upon “The Influence of Geographic Environment” (Bulletin of the American Geographical Society, xxix., 1897), and a series upon “Pueblo Arts and Sciences” (Scientific American, 1898). He and his brother, Victor Mindeleff, prepared the first exhaustive report on Pueblo architecture, and Cosmos made plans (1891) for the restoration of the Casa Grande cliff dwellings in Arizona.
