LEO JUD (1482-1542), known to his contemporaries as Meister Leu, Swiss reformer, was born in Alsace and educated at Basel, where after a course in medicine he turned to the study of theology. This change was due to the influence of Zwingli whose colleague at Zurich Jud became after serving for four years (1518-1522) as pastor of Einsiedeln. His chief activity was as a translator; he was the leading spirit in the translation of the Zurich Bible and also made a Latin version of the Old Testament. He died at Zurich on the 19th of June 1542.
