Having received his rabbinical training at Slutsk, government (guberniya) of Minsk, he went in 1888 to New York City, where he studied modern languages till 1894, in which year he went to Paris to study Oriental languages, especially Semitic studies ("élève diplômé" of the Ecole des Langues Orientales, 1897, and of the Ecole des Hautes Etudes, 1900). In 1898 he was sent by the Alliance Israélite Universelle to Abyssinia to inquire into the conditions of the Falashas; but, certain difficulties arising, he was able to proceed no farther than Cairo, where he taught for eighteen months. Returning to Paris, he was invited in 1902 to go to New York to become a member of the staff of office editors of The Jewish Encyclopedia.
