Nathan (Nata) ben Moses Hannover (Hebrew: נתן נטע הנובר) was a Ruthenian Jewish historian, Talmudist, and kabbalist; he died, according to Leopold Zunz (Kalender, 5623, p. 18), at Ungarisch-Brod, Moravia, on 14 July 1663. Jacob Aboab, however, in a letter to Unger (Wolf, Bibl. Hebr. iii., No. 1728), gives Pieve di Sacco, Italy, as the place of Hannover's death, without indicating the date. The place of his birth is equally uncertain. According to Graziadio Nepi-Mordecai Ghirondi, (Toledot Gedole Yisrael, p. 270) he was born at Cracow, but Steinschneider says that Nathan Hannover and Nathan of Cracow were two different persons.
Hannover lived for a time at Zaslav, Volhynia, and when that town was attacked by the Cossacks he fled from Poland. He went first to Prague, then to Venice, where he studied Cabala under Hayyim Cohen, Moses Zacuto, and Samuel Aboab. Later he became rabbi of Iaşi, Moldavia, and afterward, according to Jacob Aboab, he returned to Italy.
