Heinrich Bullinger

Born in 1504 in Bremgarten, in what is now Switzerland, he became one of the most important Reformed church leaders of the sixteenth century. After the death of Huldrych Zwingli, he succeeded him in Zurich and served there for decades, guiding the city’s church through a turbulent period of religious change.

He was known not only as a preacher and theologian, but also as an extraordinary correspondent. His letters connected him with reformers, rulers, and ordinary believers across Europe, helping spread ideas and strengthen ties among Protestant communities.

Bullinger died in 1575, but his influence lasted well beyond his lifetime. Readers interested in the Reformation often meet him as a steady, thoughtful figure whose writings brought together doctrine, church life, and practical faith.
