Name of a prominent Hungarian family which flourished in the latter half of the fifteenth century and in the first half of the sixteenth in Ofen (Buda). Members of three generations of it are known; namely, Jacob, Israel, and Isaac Mendel, who held the office of "Princeps Judæorum," "Supremus Judæorum," or "Præfectus Judæorum" between 1482 and 1539. This office, which seems to have existed only during that period, was created by King Matthias in order to give the Jews in accredited representative at court, who at the same time should be responsible for the payment of their taxes. The "Præfectus Judæorum" was empowered to impose fines and other penalties on the Jews. As an official of the crown he was exempted from wearing the Jews' hat.
