Heinrich Bullinger, a Swiss theologian, born at Bremgarten, canton of Aargau, July 18,1504, died in Zurich, Sept. 17, 1575. He was the son of a priest, studied at Emmerich and Cologne, became a teacher in the monastery of Kappel, and a champion of the doctrines of Luther and Zwingli. In 1528 he cooperated with the latter in effecting the conversion of the canton of Bern to Protestantism. The next year his preaching made converts of the community of Bremgarten, of which he became the first Protestant minister; but in 1531 he was expelled from the canton of Aargau and went to Zurich, where in 1532 he became pastor of the minster church. He displayed great talent, moderation, and conscientiousness in the controversies with Luther and the conflicts with the Anabaptists, and in settling the ecclesiastical differences between Bern and Geneva. His wife, formerly a nun, bore him 11 children. In 1543 he edited the works of Zwingli, and he left in manuscript Gesehichte der Eidgenossen, hesonders der Ti-guriner (4 vols.) and Reformationsgescliiclite, which latter was published by Hottinger and Vogeli (3 vols., Zurich, 1838-'40).
