Jacob ben Jehiel Loans (Yacov of Linz, Jakob von Linz, Yaakov ben Yechiel Loans) (died 1506) was an Italian-Jewishrabbi, Court Jew and personal physician to Frederick III, Holy Roman Emperor (1440-93), and who was the first Hebrew teacher to Johann Reuchlin.[1][2][3][4][5] Loans had served for at least 7 years before he met Reuchlin, and was his teacher for nearly a year.[6][7] They met in 1492. Reuchlin wrote a letter to Loans in Hebrew in 1500 that he later published, which triggered attacks from Johann Pfefferkorn, an anti-Judaic Jewish-to-Christian convert. Loans knew Reuchlin was looking to acquire a Hebrew Bible codex, and Loans arranged for the Emperor to give one to Reuchlin.[8][9][10][11] He was raised to the nobility in 1465.[12] He is also said to have been the physician to Frederick's son and successor, Maximilian I.[13]
