Book excerpt: Immanuel Tremellius (c.1510-1580) was one of the most distinguished scholars of the Reformation era. Following his conversion to Christianity from Judaism, he rose to prominence in the mid-sixteenth century as a professor of Hebrew and Old Testament studies, teaching in numerous highly prestigious Reformed academies and universities across northern Europe.
