Daniel Khvolson
Born in Vilna (Vilnius), Daniel Khvolson (Khvol’son) received a traditional Jewish religious education. He moved to Riga and then was invited to complete his studies in Breslau, where he learned German, French, and Russian. Upon converting to Christianity in 1855, he became a professor of Hebrew and Syriac studies at the University of St. Petersburg. His Die Sabier un der Sabismus (1856) not only established his expertise in Semitic studies, but also helped shape Russian-language scholarship in that field. Despite his conversion, he defended Jews against blood libels and helped to win their acquittal in numerous cases.
