Gams, Pius BONIFACIUS, ecclesiastical historian, b. all the ancient canons on the subject to be observed, at Mittelbuch, Wurtemberg, January 23, 1816; d. at Munich, May 14, 1892. His classical studies were made at Biberach and Rottweil (1826-1$34), he studied philosophy and theology at Tubingen (1834-38), entered the seminary of Rottenburg in 1838, and was ordained priest on September 11, 1839. He filled various posts as tutor, vicar, parish priest, and professor until May 1, 1847, when he was appointed to the chairs of philosophy and general history by the theological faculty of Hildesheim. Finally he entered the Abbey of St. Boniface at Munich, which belonged to the Bavarian congregation of the Order of St. Benedict, and pronounce the monastic vows, October 5, 1856, adding the name of Pius to that of Boniface. Gams filled several monastic offices, being successively master of novices, sub-prior, and prior. He is best known for his “Kirchengeschichte von Spanien”, 3 vols. (Ratisbon, 1862-1879), and his “Series episcoporum Ecclesiae catholica quotquot innotuerunt a beato Petro apostolo” etc. (Ratisbon, 1873-86, with two supplements). The “Kirchengeschichte von Spanien” is a conscientiously and methodically written work, critical, also, to a certain extent, in dealing with the earliest period of Spanish ecclesiastical history, though the author rarely abandons the aid which unreliable sources seem to furnish. The “Series episcoporum” has rendered useful service and is yet very helpful. It is a collection of the episcopal lists of all ancient and modern sees known to the author. Gaps are frequent in the lists of ancient sees, especially those of the Eastern Church. It was, of course, impossible to draw up a critical list (names and dates) for such remote times, and larger information must be sought in extensive documentary works, e.g. “Italia Sacra” and the like; as a rule, however, the author has ignored a number of scattered dissertations which would have rectified, on a multitude of points, his uncertain chronology. In 1850 Gams founded with his colleagues Alzog, F. W. Koch, Mattes, and G. J. Muller a “Theologische Monatschrift”, which lasted two years (1850-1851), and in which he published a number of essays.
