Biography. Hilprand (also Hiltprand or Hildebrand) Brandenburg was born
in 1442 the second son of a wealthy patrician family seated in Biberach, a
small town about 30 kilometers northwest of Buxheim. Not much is known of his
childhood or early adulthood. In 1459, at the age of 17, he matriculated at the
university in Vienna,[1]
but by 1467 we find him in Pavia. A year later, at age 26, Hilprand was
studying at the university of Basel, only to return to Pavia the following
year. In 1471 he took up a position as rector at his alma mater in Basel, but
soon thereafter decided to enter the priesthood. Hilprand was ordained two
years later in 1473. During the succeeding years we find him back in his
hometown of Biberach, at the opening of the new university of Tübingen (1477), and
as far afield as Rome (1479 and 1494). In the 1480s he held several
ecclesiastical positions, in Biberach, Wurzach, and Stuttgart. It seems that
soon after his return from his last trip to Italy his relationship with the
Carthusians at Buxheim became more intimate, and by 1505 he expressed a desire
to become a permanent member of that community. He was not admitted into the
ranks as a cloistered monk, but rather, given his status as a parish priest,
taken under contract as a Donate, those brothers who do not take vows but live
with the community through mutual arrangement. Hilprand died in the Buxheim
Charterhouse in 1514.[2]

Hilprand’s Epitaph. “Anno domini millesimo quingentesimo / quarto decimo [1514], die vero dudecima mensis Januarii [12 January] obiit honorabilis ac religiosus vir dominus / Hilprandus Brandenburg de Bibraco / donatus professus huius monasterii ac fundator huius capelle, cuius anima requiescat in sancta pace.”
Books. Hilprand is most interesting to us as a first-rate bibliophile. His early studies sparked in him a love of learning, and his family and profession provided him the means to amass a library that, by the early sixteenth century, would have been the envy of any noble in Europe. According to the Buxheim liber benefactorum from 1508, Hilprand would donate a total of some 450 books to the library. His own personal library would add nearly a third of the number of books available to the Carthusian monks in Buxheim by his death in 1514. Along with his books, which were of immense value, he gave money and gifts, including a donation to erect St. Anna’s chapel on the ground floor of the library building in honor of his mother, Anna Klock. It can be stated without exaggeration that Hilprand was for Buxheim the single greatest donor in its history. Of these 450 or so books, approximately 40 manuscripts and over 100 printed books have been identified.[3] They share a particularly striking characteristic in their use of a distinctive and very early printed ex libris bookplate with Hilprand’s coat of arms, as well as an annotation of former ownership and donation by a hand now recognized as none other than that of the prior, Jacob Louber, a man who took a great interest in the library at Buxheim (1502-1514), as he had at Basel (1480-1502). The two had studied together in Basel and no doubt shared a love for books and libraries.
