1799–1890
A fearless 19th-century Catholic scholar, he became one of the most famous critics of papal infallibility and a key voice in the movement that became known as Old Catholicism.

by Johann Joseph Ignaz von Döllinger
Born in Bamberg in 1799, Döllinger was a German Catholic priest, theologian, and church historian whose work made him one of the best-known religious thinkers of his time. He studied at Würzburg, was ordained in 1822, and later taught at the University of Munich, where he built a strong reputation as a historian of the Christian church.
His life took a dramatic turn during the First Vatican Council of 1869–1870. Döllinger refused to accept the newly defined doctrine of papal infallibility, arguing from history and tradition against it. That stand led to his excommunication, but it also made him a leading figure for Catholics who wanted reform while remaining rooted in the early church.
He spent his later years as an independent and widely respected scholar in Munich, continuing to write and influence religious debate across Europe. Today he is remembered not only for controversy, but for the seriousness of his historical scholarship and his determination to follow conscience even at great personal cost.
