Wilhelm Emmanuel von Ketteler
German theologian and politician who served as Bishop of Mainz (1811-1877)
Freiherr Wilhelm Emmanuel von Ketteler (25 December 1811 – 13 July 1877) was a German theologian and politician who served as Bishop of Mainz. His social teachings became influential during the papacy of Leo XIII and his encyclical Rerum novarum.
Early life and ordination
Ketteler was born in Münster in Westphalia into the Ketteler noble family. In 1828, he finished matura in Brig, Switzerland. He studied theology at Göttingen, Berlin, Heidelberg, and Munich, and was ordained as a priest in 1844. He dedicated much of his life to maintaining the freedom of the Church from the control of the State, which often brought him into conflict with political powers.
Bishophood
During the 1848 Revolutions, Ketteler was elected as a deputy for the District of Tecklenburg and Warendorf to the Frankfurt National Assembly. During this time, he became noted for his foresight, energy, and eloquence. He established a reputation for his decisiveness, rather than his scholarliness.
In 1850, Ketteler was made bishop of Mainz by order of the Vatican.

Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
