Russian author and philosopher; born April 7, 1818, at Lagow, near Opatow, Russian Poland; died at Szczebrszyn Oct. 13, 1895. Up to the age of six he received instruction in Hebrew from his father, whom circumstances had forced to become a "melammed"; after that age he studied Talmud under different rabbis of Opatow, to which town his family had removed from Lagow. The most prominent of his early teachers was R. Meïr Ḥarif, but the instruction he received was very unsystematic. Passages for discussion were selected at random from different parts of the Talmud, and during the nine years of study under these rabbis not a single volume was read byhim in its entirety. When he reached the age of fifteen he commenced to study alone. At that time his logical tendencies began to assert themselves, and his studies proceeded in an orderly and wellarranged manner: He also made great efforts to follow the same logical system in his writings and speech. From Opatow Reifmann went to Szczebrzeszyn, where he married the daughter of Joseph Maimon. In his father-in-law's house he discovered a veritable treasure of books, including the "Moreh Nebukim" of Maimonides and the "Cuzari" of judah ha-Levi. With indescribable zeal he began to read them, and before long, he knew them by heart. These, together with many works of the German philosophers, which he read and studied extensively, opened a new world of ideas to him, supplied him with a broad field for investigation and study, and afforded him the means of exercising his wonderful faculties to greater advantage. Still, he did not neglect the Hebrew language, and from time to time he wrote Hebrew poems in which he displayed wonderful poetic skill and great depth of feeling. He also carried on an extensive correspondence with such scholars as Rapoport, Geiger, Jost, Luzzatto, Kirchheim, Sachs, Goldberg, and Steinheim. With the exception of his letters to Steinheim, which dealt with various philosophical problems, his correspondence was of a critical character, and either dealt with Biblical exegetical questions or contained discussions and investigations concerning archeological subjects.
