Jacob Raphael Fürstenthal (born in Glogau 1781; died at Breslau, February 16, 1855) was a German Jewish poet, translator, and Hebrew writer.
Fürstenthal's attention was directed chiefly toward the modernization of Jewish religious services, both in and out of the synagogue, and to this end he translated into German the most important liturgical books.
His German translations of and Hebrew commentaries to the Moreh Nebukim of Moses Maimonides and the Ḥobot ha-Lebabot of Baḥya ibn Paḳuda, and especially his large Hebrew commentary to the whole Bible, evidence his great versatility in Talmudic and Midrashic literature.
Fürstenthal's main importance, however, lies in his Hebrew poetry.
His poetic productions have a classic ring, and are distinguished by diction, richness of thought, and feeling.
