Russian Hebraist and author of the nineteenth century; born at Hrubieszow, government of Warsaw. He wrote a double commentary on Job, preceded by a preface and two poems (Lemberg, 1833); and "Dibre Purim" (Zolkiev, 1834), an epic poem, the central figures in which are Ahasuerus and Esther. He began the compilation, on original lines, of a Hebrew dictionary entitled "Memalle," of which only the letter א appeared (Warsaw, 1839). Benjacob criticized this work severely in "Pirḥe Ẓafon" (2:201-208, Wilna, 1844).
