Bible Translators Theologians Johann Heinrich Callenberg (January 12, 1694 – July 11, 1760) was a German Orientalist, Lutheran professor of theology and philology, and promoter of conversion attempts among Jews and Muslims.
Sometime before 1720 Salomon Negri, professor of Syriac and Arabic at Rome, stayed in Halle for six months.
In 1728 he established the Institutum Judaicum, the first German Protestant mission to the Jews, to which he attached a printing-office.
Frommann translated the Gospel of Luke with commentary which was revised and reprinted by Raphael Biesenthal in the 19th century.
Callenberg also sent missionaries to other European countries, and was a patron of converted Jews.
