EINHORN, David, born in Dispeck, Bavaria, 10 November 1809 ; died in New York City, 2 November 1879. He was educated at the rabbinical school of Fuerth, and subsequently at the universities of Munich and Wurzburg. Espousing the cause of radical reform in Judaism, he was chosen rabbi at Hopstadter, and afterward chief rabbi of Mecklenburg-Schwerin. He was called to Pesth in 1851, where his advanced views met with such opposition that his temple was closed by the Austrian government. In 1855 Dr. Einhorn was invited to assume charge of a Hebrew congregation in Baltimore, Maryland, and during his incumbency published a prayer book, which has a wide circulation in the United States, and also a German magazine, "Sinai," devoted to interests of radical ref6rm. In 1861 he was such a staunch Unionist that his Baltimore pastorate was exchanged for one in Philadelphia. In 1866 Dr. Einhorn removed to New York, where he held a rabbinical position till his death. A collection of his addresses has been issued in German.
