The New International Encyclopædia/Czekanowski

CZEKANOWSKI, chĕ’ka-nō̇v’skē̇, Alexander (1832-76). A Russian explorer. He was born in Volhynia, and studied at Kiev and Dorpat. Banished to Siberia in 1863 because of his participation in the Polish insurrection of that year, he was five years later permitted to settle at Irkutsk. Here, as the agent of the Imperial Geographical Society, he began a series of geological investigations extending along the Lower Tunguska, the Olenek, and the Lena, the results of which were published chiefly in Petermann's Mitteilungen (1874 et seq.). Amnestied by the Government, he returned to Saint Petersburg, where, during an attack of melancholy, he committed suicide.
