1534 - 1572 (5 Av 5332) ISAAC LURIA (HaAri Hakadosh - Sacred Lion) (Egypt-Eretz Israel)
Born in Jerusalem, he moved as a child to Egypt where he became a scholar and began to study Kabbalah. There he spent seven years in isolation on an island on the banks of the Nile, visiting his family only on the Sabbath. He wrote a commentary on Sifra di- Zeniuta, an important section of the Zohar. In 1569 he moved to the "Holy City" of Safed, and became known as the founder of modern Kabbalah. His most famous pupil was Hayim Vital. Joseph Caro also studied Kabbalah with him. The latter was responsible for disseminating his ideas. The Ari was also known as a liturgical poet and many of his songs were published in a manuscript called Har Nof. Some of these hymns (including Yom Ze LeYisrael) are still sung on Shabbat during the meals in many Jewish homes.
