Born July 18, 1504, in Bremgarten; died September 17, 1575, in Zürich. Active in the Reformation in Switzerland.
Bullinger was a friend of H. Zwingli and was his successor in Zürich in 1531. By concluding an agreement with J. Calvin in 1549, he united the Calvinist and Zwinglian movements in the Reformed Church. This unification was expressed also in the Second Helvetic Confession, which Bullinger compiled in 1556 and which was one of the creed books of the reformers.
