Isidor Kalisch. A Guide for Rational Inquiries Into the Biblical Writings: Being an Examination of the Doctrinal Difference Between Judaism and Primitive Christianity.

Prussian-born Isidor Kalisch (1816-86) was an American reform rabbi, and writer. In 1849 he came to the United States and in 1850, was called to the Tifereth Israel congregation in Cleveland, Ohio, where he labored in the interest of the ultra-reform element in Judaism. In 1855, the first conference of rabbis was held in Cleveland and a ritual and common prayer-book was agreed upon, entitled Minhag America, which Kalisch edited together with Rabbi Isaac Mayer Wise.
