Ulrich Fugger, der Ältere

By contrast, the younger line, Fugger von der Lilie, flourished and became not merely a branch of the family but the root of its later greatness. Its founder, Jakob I, expanded the family's business interests and in 1466 achieved membership in Augsburg's merchant guild. When he died in 1469, his widow and sons Ulrich (1441–1510), Georg (1453–1506), and Jakob (later known as "the Rich"; 1459–1525) pursued his business. So great was their success that Ulrich Fugger and Brothers became the leading mercantile firm in Augsburg. By 1473 they had received an imperial patent, allowing them to bear a coat of arms.

The Biblotheca Palatina grew by leaps and bounds under Ottheinrich's successor Elector Friedrich III, who ruled from 1559 to 1576, through the book collection of Ulrich Fugger of Augsburg. This collection contained some 500 parchment and 800 paper manuscripts as well as 8,000 prints. Fugger, who had converted to Protestantism, bequeathed his collection to the library in 1584. The collection had been housed in the Holy Ghost Church following his move from Augsburg to Heidelberg. Following Fugger's bequest, the Bibliotheca Palatina enjoyed its reputation as the most significant library north of the Alps.

Wikipedia: "Jakob's eldest son, Ulrich, took over the business on his father's death, and in 1473 he provided new suits of clothes to Frederick, his son Maximilian I, and his suite on their journey to Trier to meet Charles the Bold of Burgundy and the betrothal of the young prince to Charles's daughter Maria. This started the very profitable relationship between the Fugger family and the Habsburgs.

With the help of their brother Markus in Rome, Ulrich and his brother George handled remittances to the papal court of monies for the sale of indulgences and the procuring of church benefices. From 1508 to 1515 they leased the Roman mint. Ulrich died in 1510."
