1437 - 1509 (6 Av 5269) DON ISAAC ABRAVANEL(Abarbanel) (Spain)
Philosopher, financier and scholar. He interceded many times on behalf of his fellow Jews, including trying to stop Ferdinand II from expelling them. In 1492 he was foiled by Torquemada and followed them into exile. His commentaries cover the major and minor Prophets. Consistent with his belief that the Messiah would come in his lifetime, he also wrote three messianic texts called Migdal Yeshu'ot (Tower of Salvation).
