Peter Von Koppen, a Russian archaeologist, born in Kharkov, Feb. 19, 1793, died at Kara-bagh, Crimea, June 4, 1864. He studied in the university of Kharkov, and devoted himself at once to researches on the history, ethnology, and material condition of the Russian empire. The first fruit of his labors was the Uebersicht der Quellen einer Literargeschichte Russlands (St. Petersburg, 1818), which was followed in 1822 by a collection of Slavo-Russian antiquities and facsimiles of manuscripts. His Nordgestade des Pontus (Vienna, 1823), Die dreige-staltete Hekate und ihre Rolle in den Mysterien (1823), and his articles in German periodicals on the antiquities and arts of Russia, furnished valuable materials for archaeological researches. In 1827 appeared his Materialien zur Cultur-geschichte Russlands. At this time he entered the service of the government, investigated the productiveness and hydrography of the provinces of southern Russia, and published several works on the results of his researches. His numerous travels through the empire gave him a thorough acquaintance with the various elements of the population, and he published in the following years several highly esteemed ethnological works, among them Ueber die Na-tionalitdt der Bewohner verschiedener Gouverne-ments, Ueber die Vertheilung einzelner Volker-stdmme, and Ueber die Deutschen im Peters-burger Gouvernement. The final result of these labors was a large ethnological chart of European Russia, published in 1851. His last important work is an exhaustive treatise on the ninth census, Demataya reviza (St. Petersburg, 1857). He spent his last years on the estate of Karabagh, presented to him by the emperor.
