1504–1575
A central voice of the Swiss Reformation, he helped steady and shape the movement after Huldrych Zwingli’s death. Through preaching, teaching, and widely read writings, he became one of the key Protestant leaders of the 1500s.

by Pietro Martire Vermigli, Heinrich Bullinger
Born in Bremgarten, in present-day Switzerland, Heinrich Bullinger studied in Cologne and was drawn to the ideas of reform early in life. He first served as a teacher and preacher at the former Cistercian abbey at Kappel, where he built a reputation as a thoughtful pastor and writer.
After Huldrych Zwingli was killed in 1531, Bullinger succeeded him as leader of the church in Zürich and pastor at the Grossmünster. In that role he worked to stabilize the Swiss Reformation, and his influence spread far beyond Zürich through sermons, letters, and theological works.
Bullinger is especially remembered for helping define Reformed Protestant belief. He was connected with the Helvetic Confessions, and his writings were read across Europe. Historians also note his enormous correspondence, which made him an important link among Reformers in many different countries.
