Theodor Granderath
German historian (1839–1902)

Theodor Granderath (19 June 1839, Giesenkirchen, Rhine Province – 19 March 1902, Valkenburg, Netherlands) was a German Jesuit scholar.
Life
After completing the course in the gymnasium at Neuss, he studied theology in the University of Tübingen, and entered the Society of Jesus at Münster, Westphalia (3 April 1860). Between 1862 and 1874 he finished his studies in the classics, philosophy, theology, and canon law.
In 1874 he was appointed professor of canon law in the college of Ditton Hall, England, where from 1876 to 1887 he taught dogma and apologetics. In 1887 he was sent to the college of the Society at Exaeten, Netherlands, to succeed Gerhard Schneemann in the preparation of the Acta et Decreta Concilii Vaticani. This was completed in 1890.
In 1893 he was called to Rome, where Pope Leo XIII placed the archives of the First Vatican Council at his disposal, with a view to a history of that council. In 1897 and 1898 he replaced the professor of apologetics at the Gregorian University. In 1901 failing health compelled him to retire to the college at Valkenburg, where he prepared the first two volumes of his history of the Vatican Council.
Works
In preparation for his work on the Vatican Council he first edited the Acta et Decreta sacrosancti oecumenici Concilii Vaticani (Freiburg im Br., 1890), the seventh volume of the Acta et Decreta sacrorum Conciliorum recentiorum in the Collectio Lacensis.

Why this record matters
The phrase “german historian (1839–1902)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Sep 1, 2026. The linked authority identifier is Q7781588. VIAF identifies the subject as 23167927. The Library of Congress control number is n87819066. 4 of 4 selected statements include explicit references; 0 carry qualifiers and 1 use preferred rank. The first chronological checks are 1839, 1902, 1860 and 1862.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. 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.
